no dark center to cap as per description of PNW Mycena key, no mention of that extremely shaggy stipe bottom shown here in your photo:


pale gray gills w/paler edges fits, as does snowbank hab in pine needle duff.

not gregarious or clustered.

It has never knowingly been collected at the spring Sierra Fungi class, either.

however, if it is really the most common WA snowmelt mycena, and you are well familiar with it, then, maybe…

woulda been a nice save, to confirm microscopically.

What doesn’t fit M. overholtsii it the cap shape, how far the translucent striations go up the cap and solitary growth on needle duff.

how did you make this determination?

Despite the fruit bodies appearing to occur singly, unlike the normally clustered overholdtsii, this Mycena does have the very fuzzy stipe base and snowmelt association of overholdtsii.

M. hudsoniana is also a snow melt Mycena, but only recorded from WA and OR, and this mushroom does not fit the descriptioon of hudsoniana on the PNW Key Council key to mycena here:

CAP 2-5 cm, hygrophanous, blackish on disc, dark gray toward margin, fading to “pale smoke-gray”; bald and polished, moist, striate when wet, somewhat grooved when old or when faded; flesh firm but fragile. ODOR mild or faintly fragrant. TASTE mild or only slightly subnauseous. GILLS adnate, ascending or with a decurrent tooth, 25-30 reaching stem, narrow (scarcely 0.2 cm); pale smoke gray, edges pallid. STEM 3-5 × 0.15-0.3 cm, equal, very fragile; colored as cap or slightly paler in upper part; with a faint bloom at first (pruinose), soon polished and watery. HABITAT on needle beds under conifers (Smith), restricted to conifer forests and usually found on woody debris or duff near snow banks above 700m. (2300 ft.) elevation, April – July, (Castellano et al. 1999). DISTRIBUTION at least WA, OR.
