When: 2008-01-21

Collection location: Clinton, Whidbey Island, Island Co., Washington, USA [Click for map]

Who: Sam Linse (BearwoodSam)

No specimen available

Found in small groups or alone in mature mixed coniferous second growth forest of Douglas Fir, Western Red Cedar, Western Hemlock.
Cap approx. 2-3cm, conical with long fibers, brownish turning lighter near the edge.
Gills are buff when young turning cocoa brown later. Fairly close together and look to be free of the stem.
Stem is a rich brown with longitudinal fibers and some frosty scales too. It lightens in color as it nears the small abrupt whitish bulb.
Sorry for the blurry image, but was the only one showing it in situ.
I think Inocybe because of the fibrous cap, smallish size, lack of ring, habitat.
Any ideas?

Check for turnip-shaped bulb

That’s the clue to napipes. Actually, I. napipes lacks a pruinose stipe, but, based on an evolutionary analysis, it appears derived from ancestors that did possess a pruinose stipe (and many with a marginate or bulbous stipe base). In my experience, I really don’t get much of an odor out of this and things in the I. assimilata (=umbrina) group. Inocybe napipes has more coarsely nodulose spores than I. assimilata in Europe. See if you can observe very young fruitbodies and detect a cortina, and make a voucher collection.

Will smell soon…

Thanks Joshua, I’ll go back and take a sniff.. Seem to be a lot of them right now.

Inocybe napipes grp?

I would definately say Inocybe! I would probably point you to something like Inocybe napipes/assimilata grp. because of the innately fibrous cap and the entirely pruinose stem with a basal rimmed bulb. Did you get a good sniff?? I. napipes has a very repulsive, coal tar gas like odor very different from the usual farinaceous/spermaic odors…
