Received a mushroom identification request this week for a fungus growing on the ground under a "spruce" by Harrigan Centennial Hall. The fungus in the photo I was sent was pretty clearly a Suilllus because it had a veil that was cream colored, lacked glandular dots on the stem and wasn't associated with Larch. The character that jumped out the most from the photo was the brown bruising of the pores, definitely not something I had seen around here.
I tried to run through the key to Suilllus on the Pacific Northwest Key Council site, but the photo lacked information about several key features used in the key (viscidness was the first).
Once I had it in hand the following were the characters that I used to help me identify ( or misidentify) it:
Cinnamon brown cap with very fine fibrous sort of look, it was not viscid, but had a few needles stuck to the cap
Cap turning dark with KOH
Pores yellow, bruising red brown
Veil didn't form a distinctive ring, more of a zone on the stem, there were a few fragments on the cap rim
Stem solid, slowly and indistinctly turning blue-green
Associated with Douglas Fir
I used Mushroom Matchmaker: Mushrooms of the Pacific Northwest (handy synoptic key) as my texts were at home and I was anxious to try the program out again. It pretty quickly took me to Suillus lakei (Yeah, a name!), reading the description, it seemed to fit pretty well and there was enough variation in the photos available on Mushroom expert that I decided that it was a positive identification.
I looked at a few similar species (in my mind) e. g. Suillus caerulescens and dismissed it because of the lack of a distinctive color reaction in the stem of the fungus in question.
I started feeling a bit less certain when I looked at the descriptions and photos in Mushrooms Demystified (Arora) and Mushrooms of the Pacific Northwest (Trudell and Ammirati). For one the lakei were all pretty red and/or fibrillose looking and what reinforced the sense of disquiet was the lack of discussion in the descriptions of species that I thought were similar. Why didn't neither book's discussion of lakei talk about how to distinguish it from caerulescens? What was I missing?
It seems like I was perhaps not paying enough attention to the overall color the cap of lakei (reddish) vs cinnamon brown (caerulescens) that is distinctive enough to rarely cause confusion and the more extensive fibrils found on lakei .
This is a brief synopsis of the small group of Suillus species included in Arora and Boletes in the PNW) that have ring zones, yellow pores that stain brown that are found with Douglas Fir.
S. ponderosa: has a viscid, bright yellow veil and a smooth cap
S. lakei: fibrillose with reddish brown to brick red or pinkish fibrils (occasionally tawny). Viscid when wet, stalk weakly turning blue or green when cut
S. caerulescens: dry, whitish veil, cap smooth or fibrillose, viscid when wet, stalk turning blue or green when cut, sometimes slowly.
I found myself leaning back toward S. caerulescens at this point, the lack of fibrils is starting to seem like a problem. Still a bit uncomfortable with the identification, I turned to another book (A. H. Smiths and H. Thiers monograph on North American Suillus) and was relieved to finally see the difference between these two species addressed.
" It (caerulescens) differs from S. lakei in having a distinct change to blue in the stipe and in having numberous large latifciferous ducts in the context of the cap. ..."
Well, now I have to make a judgment call; are the fibrils more important than the blue reaction? I did pick another sample today and cut it open fairly quickly after picking. It did turn blue, not abundantly, but more so than previously. No real joy yet.
Guess I'll have to look for lactciferous ducts next.

DYCs! Because there aren’t really that many native yellow composites in SEAK, I don’t often have to use DYC too often anymore. Then one day, I decided it was time to get better acquainted with the weedy species around town.
The two plants that caught my attention were growing in the gravel at the edge of the road to the work float near the island side of the O’Connell Bridge. The yellow ray flowers, milky juice and clasping leaf bases made the genus identification fairly straight forward for both plants; Sonchus or Sow thistle. I wasn’t so sure about the species identification of either plant.
At this point, I should confess that I tend to use keys to identify plants, then look at the descriptions and photos/drawings, so the following paragraphs mostly talk about comparing the keys in various books.
I first consulted Invasive Plants of Alaska which includes a description of perennial sow thistle (S. arvensis ssp. uliginosus) and a paragraph about differentiating one species of annual Sonchus (oleraceus) from the perennial one. This text focused on the long horizontal root systems found in the perennials. There was a photo of the leaf base of the perennial (rounded) and the annual (had longish pointy auricles).
Neither plant had a well developed root system, but they might not if they were first year plants. So I looked for additional references.
To sum up this book focused on the root system and auricle shape. S. arvenis has a large root system and rounded auricles.
The key in Hitchcock and Cronquist also referred to differences in the root systems, but added size of flower heads; perennial are 3-5cm and annuals species 1.5-2.5 cm. Lastly, H & C included gland tipped hairs as a characteristic of S. arvensis (this character turned out to be a bit of a red herring). One of the plants had this character, so despite the flowers being a bit on the small size, I was pretty certain that one of the species was arvensis.
To sum up H& C use root system, flower head size with a mention of glandular hairs.
Because the line drawings didn’t really fit what I had in hand, I decided to consult another reference. FNA treatment
This key begins with leaf base auricle shape, number of ribs on the cypsela (fruits) and introduces the idea that one of the species treated as an annual in the last two references, could be a biennial.
Second decision in this key involved life history as well as stem hardness (…”stem bases soft to hard, herbaceous, often hollow” vs. “stem bases hard, sometimes more or less woody”. I think I’ll emphasize the woodiness issue.
Once a direction is chosen, the leaf blade shape is important in differentiating S. oleraceus from S. ternerrimus (leaf blades more or less deltate to lanceolate with the terminal lobe larger vs rhombic to lanceolate and equal sized.
Between arvensis and palustris; geography helps (Ontario vs. widespread) and the leaf base. S. arvensis is rounded and palustris acute auricles
To sum up the FNA (widespread spp only, this removes ternerrimus and palustris from consideration)
S. asper has recurved auricles and fruit with 3 ribs on each face annual or biennial
S. oleraceous: has straight auricles, and lobed leaves with a larger terminal segment and often hollow stems.
S. arvensis: straight auricles, hard stem base, rounded auricles and dark brown cypsela at maturity.
Although I already had a bit more information than I wanted, I decided to consult another favorite reference; Anderson’s Flora of Alaska
Although there was common ground between this and other treatments, another new character came into play; involucres bract length. Also, this key indicated that the annual species could have stipitate glands.
S. arvensis: perennial, involucre bracts more than 14mm long in fruit, pubescent with stipitate glands
S. asper:annual, involucres less than 14mm, leaves with sharp and narrow pointed teeth, cypsela not wrinkled, but longitudinally nerved
S. oleraceus: annual, involucres bracts less than 14mm, leaves sharply and broadly toothed, lyrate pinnatifid (handy character), cypselae transversely wrinkled and longitudinally nerved
I had one last reference at my disposal; the Illustrated Flora of British Columbia . Fortunately the descriptions fit in pretty well with those found in H &C and Anderson.
S. arvensis: perennial, heads 3-5cm
S. oleraceus: annual or biennial: flower heads 1.5-2.5, cypselae several nerved and wrinkled
S. asper: annual or biennial, flower heads 1.5-2.5 cm, cypselae several ribbed, not wrinkled.
The handy thing about these taxa is that there doesn’t seem to be any noticeable disagreement in the taxonomy, just a bit of variation on which characters might be useful and a bit of haziness about how variable the presence/absence of certain character (glandular hairs).
So the synopsis of all keys
S. arvensis: perennial, straight auricles with rounded bases, may have woody stems, they may also be hollow, heads 3-5cm stipitate hairs present on the flower stems, and dark brown cypselae at maturity
S. asper: annual or biennial, stems not woody, may be hollow, leaves with sharp and narrow pointed teeth recurved auricles. Flower heads 1.5-2.5 cm and involucres bracts less than 14mm, fruit with 3 ribs on each face, not wrinkled
S. oleraceous:, annual or biennial, stems not woody, may be hollow. Leaves sharply and broadly toothed, lyrate pinnatifid, auricles straight, cypselae transversely wrinkled and longitudinally nerved
At this point, I’ve decided that for unambiguous identification (at least the first time around) I need mature seeds.
Back to the actual plants in hand; both have flowers less than 3cm (but neither are really fully open). Neither root system is obviously forming horizontal branches. The fruit aren’t fully mature, I can see ribs, but it isn’t clear if they are or will be wrinkled
One has rounded a
uricles, some stipitate hairs and very pointy large teeth on the leaf margins, the leaves are also darker and thicker. (I’m going with S. asper)
The second has straightish auricles with pointed bases, no hairs and less menacing teeth, the leaves are lyrate pinnatifid (like a dandelion) with a larger terminal segment. (going with S. olerace
us)

It was next seen in the lawn at a house on the south end of the commons. From there it worked its way south along the shore past Litman's then went up the cliff from the transformer for my lot. There wasn't any sign of it sticking around the house though.
From Phil Mooney we heard that the bear had swam to Morne then to Kutkan Island. Fish and Game attempted to capture it so they could collar and move the bear, but couldn't get a safe shot. Deirdre and I saw the bear later in the day swimming near Kutkan island, then it climbed ashore.
We kind of relaxed out here for a day, but last night the bear reappeared at the Pendell's house (the beach near the deck), they scared it off, then it went to the Goffs (on the porch at the front door) and was shooed away. This morning we had a call from the Litman's reporting the bear was in their garden, then it wandered to the cabin and disappeared. It sounds like it also visited the Rush's island. At some point, it wandered up here and tore into the rhubarb, riffled through the compost and moved the mink trap (no bait). We searched the rest of the garden (banging our pot lid) but didn't find any other sign or tracks.

I first encountered maples in Alaska in 1981 near Neka Mtn on a limestone outcrop (other plants from the site include Polystichum lonchitis, Polemonium pulcherrium, and Asplenium trichomanes ramosum (viride) on a trip to the Eva islands on the Romance. That lone maple had a large canopy overhanging the beach. Over the years I’ve noticed a few trees along the Peril Strait shore (Lindenberg head, near Todd) in the fall when the leaves had turned bright yellow, but it encounters with native maple are rare for me.
On a trip to False Island this last weekend, I was lucky enough to find another one. Searching for plants wasn’t the goal of the trip, we were there to set up 4 deer exclosures to try to get at the effect of deer on vegetation in treated clear-cuts (thinned or gapped). At the end of the first day we were close to a beach and decided to spend a few moments on a sunny beach (young growth tends to be a bit dark). Fortunately, I can’t seem to resist walking down a beach and so found the maple. What drew me in was the luxurious growth of Lobaria pulmonaria on the trunks. It was only later that I noticed the opposite twigs (no leaves yet). Besides the Lobaria, the trunk had healthy growth of Metzgeria, Porella, and a bit of Ramalina (sp).
This small maple tree (to 5 m in Anderson and 10m in Pojar) is easy to recognize as such, it has pretty typical looking lobed leaves and samaras that most people associate with the genus. Characteristics that separate this variety of maple from the species include; red stems and shallowly lobed leaves with lobes > 6cm across. The flowers are yellow-green (not that I’ve seen them) as are the young v-shaped samaras.
Douglas maple is reported to be dioecious (separate staminate and pistillate flowers on the same plant), it seems like the ratio of male to female flowers on a given plant might be variable. The seeds are wind dispersed and reportedly have limited viability (?) and require a stratification period.
E-Flora BC has a nice photo and write up for this species.

I've started tagging the blooming plants with labeled flagging so I can track the plants through to fruiting. I've never been convinced that the berry color is consistently darker in the Alaska blueberry, but that could be because I not sure which plant is which by the time they have fruit. I'm also hoping to collect a few leaves from each plant for DNA extraction/analysis to see if there is a consistent molecular difference. The work from last fall is a bit inconclusive as yet.
Golden crowned sparrows and a Hermit thrush have been on the island the last few days.

I've had a few posts planned this spring about trips and what is blooming when, but they don't seem to be materializing just from thinking about writing them. Strange.
I did have the opportunity to go to Three Entrance Bay on Friday with Scott Harris and Sandra Lindstrom (visiting phycologist). We had a couple of short hours on the island so that Sandra could collect taxa of interest to her and I could soak up as much information as possible. I need a seaweed refresher a bit more often than once every 4 or 5 years.
My eyes were pretty focused on the algae and my ears on the sounds of a Common loon, winter wren and a Varied thrush or two. I'm almost embarrassed to to say that I hardly noticed any invertebrates, yes there were black turbans, a gumboot chiton, green anemones, ochre & sunflower stars and a black katy, but I'm pretty sure that another person would have noticed many more. My eyes were feasting on the chlorophyll rich kingdom. The seaweeds look so lush this early in the year, that it was hard to see anything else. There wasn't herring spawn in that bay or outer coast, so it was easy to see all the features of the blades.
A few algal highlights for me was tasting the Alaria marginata (excellent), it seems like it would be a nice complement to the black seaweed. Alaria has the added feature that each blad
The photo on the right is a bit odd, but shows the iridescence of Mazzaella phyllocarpa, a red alga. It is probably relatively common, but isn't so easy to notice except when the light/angle is right.
Crowberry (Empetrum nigrum) was blooming on the rocks.

The below freezing temperatures were behind us for a couple days last week. It might have been Monday that it was sunny and I managed to get to town early enough to walk to work. Rewarded with the sight of some early blooming crocuses. These were benefiting from a large heat sink (building and pavement) and a southern exposure. The latter doesn't seem to be enough to bring the crocuses in my garden out of the ground.

The return of warm weather over the last couple of days brought out a couple of birds that I haven't seen for several weeks. I flushed a snipe was in the small creek in the commons (the camera was safely tucked in the back pack) this morning on the way to town. This evening was lucky enough to spot a Western screech owl on a very short branch of a Red alder in the commons. It was near the two larger shops where I saw I've seen the last few birds.

I've been counting birds on my commute between island and Crescent harbor again this fall and winter. It took awhile for me to get motivated this fall as there just weren't that many birds to count in September. I've been fairly faithful about counting since early October, keeping the data in a daily calendar instead of a spread sheet. The data entry will no doubt be great fun.
For at least a month now, I've been seeing birds that I couldn't quite make up my mind about. They were definitely alcids of some sort, just hadn't a good enough look at to decide which one. At first they reminded me of guillemots, just lacking the white wing patch. Some sort of murre made the most sense based on the features I could see. Given that winter Common murres have a distinctive black line on their cheek and winter Thick billed murres have a mostly black head, I decided that the mystery birds were most likely winter Thick-billed murres. I saw or thought I saw white on the chest so decided that these birds weren't in breeding plummage.
This last week, I've managed to get close enough to get a few photographs. I'm not sure about all of the birds I've seen the last month, but the birds in the photo seem to be Common murres in breeding plumage. The bill is thick, but doesn't seem to be the quite the right shape, the flanks are streaked and I'd be hard pressed to describe this bird as blockier than the rest of the Common murres that I've seen.
About half the birds I'm currently seeing on the commute are clearly winter plumage Common murres and the other half the same species in breeding plumage or possibly Thick-billed in some cases. Given that the birds reminded me of guillemots (all black chest) it might be safe to assume that most of the birds were breeding Common murres. Hard to say for certain though.
Now I'm pretty curious about the timing of plumage change in murres. Does it start this early most years or is it pretty variable? Guess I should add notes about plumage in the future.

Finally managed to get up to the Upper Cross trail sampling site to change out the ibutton early in the afternoon. The trail was crunchy with ice and as I walked up the trail through the woods, Varied thrushes (at least 20) flew up and away from me. I was a walking illustration of a bird plow. Also saw several juncos and Pacific wrens, 2 Hairy woodpeckers and a Song sparrow. Heard Pine siskins, Crossbills, Chickadees and Kinglets.
I hadn't been in the Gavan site since I put out the ibuttons out on October 28th, so I assumed that it might take awhile to locate them. I was correct, in fact I was getting worried that I wouldn't find it in the time I had available. So in the interest of finding the tree again, I took a few photos.

The main commons on Galankin island looks like a place recovering from intense industrial activity. In fact the land is more the equivalent of newly deglaciated as most of the area is fill related to the quarrying of rock for runway expansion in the 1960s. I'm not positive if the fill changed the shoreline of the island significantly or if the fill was just to even out the access to the quarry.
The vegetation is mixture of native and non-native pioneer species: Alnus rubra, A. viride var sinuata, Salix sitchensis, Rubus spectabilis and a few very sad looking Picea sitchensis and Tsuga heterophylla. The herbs include: Ranunuculus repens, Veronica americana, Aruncus diocus, Equisetum varigatum, Heracleum maximum and several species of Carex.
There is a pretty wide footpath through the commons that is part of the trail system connecting the common dock to most of the island lots. There are also 2 large, functional but ramshackle sort of buildings, and a couple of sheds filled with semi-abandoned long-line gear and outboards.
There is a small creeklet from the lake that enters the ocean via the lot on the south end of the commons.
Besides being an interesting place to look at plant succession, the commons has been a great place to see a good variety of birds. The mixture of vegetation, open ground, puddles and the small creek draining the lake seem to provide a variety of food sources and cover. Last fall I stalked Western Screech owl(s) in the commons, but this year I'm seeking Common snipe.
This isn't the first year I've seen snipe in the commons, the creek and brush seem to be to their liking. Typically I see a single bird that disappears mid fall, but this year I've seen multiple birds and they seem to be sticking around (or surviving?) longer. The high count was 4 birds on the 5th of November. The last time I saw a single snipe was the 30th of December.
I found the snipe in the typical fashion, that is getting very close without seeing them, snipe exploding into the air, and me jumping out of my socks. I have tried walking slowly and quietly while watching/looking carefully while I walked through the commons to see if I could manage to get a bit closer before they flushed. These efforts have met with a variable amount of success. Snipe are really hard to see for those of us that rely on a bit of movement to see well camouflaged birds. They also are really good at holding still until the last second. The best I've done is when a flock of juncos were working the ground. The juncos weren't spooked or were at least more tolerant of my walking. This time the snipe walked out of view behind the brush. Trying to get closer was not so successful.
I was kind of hoping to get a photo of a snipe, so I've taken to walking with my camera ready through the commons. No photos of snipe yet, but some great blurry "art" photos of shrubs.

The green sign individuals were growing in fairly tight groups, but not truly caespitose (not fused). They are darker, not striate at the cap margin and have fairly cobwebby veils that leave a ring zone on the stem. The caps had small dark fibrils or what might be called very minute scales. The stem base seems a bit bulbous, not not extreme. I cut cross sections of the gills and searched in vain for clamps at the base of the basidia.
The yellow-brown ones are both lighter in color and a bit different hue. The cap margin is noticeably striate. The veil didn't seem as cobwebby, but I didn't find many that still had intact partial veils. The other important feature is the fusion of the stem base. There were several groups of two or three in the lawn with stems fused at the base. There were minute dark fibrils, but nothing terribly noticeable without a dissecting scope.
In Trudell and Ammirati's Mushrooms of the Pacific Northwest there is a fairly accessible discussion of the species that are known to occur in the PNW which I'll summarize:
A. nabsnona: smooth reddish-brown cap, pale upper & dark lower stipe, not cespitose, hardwoods
A. ostoyae: dark scales on cap, strong brownish ring, stipes often fused in clusters or bases enlarged, conifers and hardwoods
A. sinapina: slightly smaller cap than ostoyae, more of a cobwebby veil, cespitose in smaller clusters than ostoyae, usually with conifers
A. gallica: pinkish brown color, white cobwebby veil, bulbous based stipe, not cespitose, hardwoods
Based on this book, I'm leaning toward A. sinapina despite it being fond of conifers. How far do away can the conifer be? Does buried conifer debris work? Trudell and Ammirati note in the text that ostoyae and sinapina can be difficult to distinguish from one another, so I'm not betting my savings on this identification.
Then there is the key to North American Armillarias posted by Tom Volk. There are a few differences in species options; no ostoyae, add in solidipes and NABS XI.
We can eliminate nabsnona (no clamps seen), NABS XI (lacks double ring), and solidipes (ring isn't thick, no scales). The character used to distinguish between gallica and sinapina, is the size of the annulus cells. I did find some that looked larger, but haven't managed to get the micormeter and slide in the same location as yet. A. gallica is rare in the west, so it is probably less likely to be in the green.
The treatment in Mushrooms Demystified groups all of the species in Armillaria mellea group so wasn't of much help in this case.

The mushroom was somewhat aromatic, not almond-like though.

There were a number of flowers blooming on the beach: Fragaria chiloensis, Arabis hirsuta, Carex macrocephala and Dodecatheon pulchellum and my favorite grass, Hierochloe odorata (by whatever name it goes by these days).
I suspect there is more of it growing further down the beach, but our time was limited, so didn't get to look on this visit. Given how quick the walk is to this beach, I really need to visit a bit more often.

We circumambulated the lake, not too troublesome, there was only one steep bit of shore line and it didn't require any scrambling.
A few of the areas of flat shoreline had small pockets of fen-like vegetation: Carex lenticularis and/or aquatilis dives, Callliergon cordifolium, Sphagnum, Sanguisorba and Caltha palustris. No sign of toads or beaver, but there was sign of bear and deer use.
The weather was sunny and calmish on our walk around the lake, but seems to have blown up rather fiercely from the south toward the evening. The boat was doing some serious bouncing around, so we opted to eat dinner on the beach . Managed to get back to the boat during a bit of calm weather, but had a pretty bumpy night in the anchorage.

A couple of weeks ago I found several (I counted 7) Gyromitra esculenta growing through the weeds and moss (R. loreus) near the burn pile. None were growing in the ash, although one was just out of the ash zone with alot of Funaria hygrometrica. The largest was just over 5 inches tall, the smallest at this point was around 2 inches. The fungi still look pretty fresh today.
To confirm identification I relied on the wrinkled, folded nature of the cap, detachment of the cap from the stem, the relatively slender stem and the presence of 2 oil droplets in the spores.
This fungus is typically listed as a saprophyte, but may also be mycorrhizal. I froze three of the sporocarps for DNA extraction. I'm hoping to build up a reference library to help identify the fungi we isolate from soil. Despite the species name, don't eat this one, it has been reported to cause fatalities.
Two good resourses online are: Tom Volks and Mushroom Expert's
Another fungus fruiting in the garden is Agrocybe praecox

I see individual Pelagic cormorants most days commuting to town, but rarely see them in groups on the water. On land, it seems to be pretty normal to see large groups, I've counted up to 80 cormorants on the rocks west of Galankin. Last week in Klag Bay, we saw a group of 12-16 more like I tend to see Pacific Loons, in fact the lighting was poor and I assumed that they were loons until I got a better look at them. Since that time, I've noticed a few large groups of Pelagic cormorants. Perhaps something that happens when large schools of herring are around or a breeding season behavior?
Totally unrelated, I saw a Little Brown Bat on the way home. It fluttered across the trail not to far below the house and into a group of young hemlocks.
