[PNW Key Council Foray]

On rotten wood (log). Caps 1cm or less, stems 2.5cm or less.

Thanks to Noah Siegel and David Largent for their interest and help: suggesting the name and sending the description. The match looks pretty good, the main difference that I can see being the spore shape. In the drawing that came with the description, the spores seem a bit less regular (equilateral) and less angular.

Species Lists


Spores hexagonal, almost equilatereral. Note how they arrange themselves here into a regular (honecomb) tiling. Spore diameter in the range 8.5-11.
No reaction of pileal tissues or spores in Melzer’s.
Caulocystidia mixed with basidia on the stipe apex.
The same. Basidia measured 33-44 × 12.5-14, with sterigmata 2.5-5.
Caulocystidia difficult to extract; 25-45 × 4-7.
Thinner stipital cells (3-12), clamped.
Cheilocystidia mixed with basidia; same shape as caulocystidia, but rarer. There were no pleurocystidia.
A couple of cheilocystidia, separated with obvious difficulty.
Pileus without a noticeable pellicle. The hyphae are 8-13 wide. Some here have outgrowths, which is rare.
Some thinner pileal cells are clamped.
A distinctive cell (not rare) in the stipe tissue. Lactifers?

I am surprised that you have not posted any micros to this observation, when you usually do it for your Mycena MO observations. That would help. Adolf
