Observation 117728: Clitocybe subditopoda Peck
When: 2012-10-26
Herbarium specimen reported
0 Sequences

Small tan/brown single mushroom found under hemlock/oak. The mushroom has a stipe with a white fuzzy base and a centrally depressed cap. See picture for size. Gills are adnate to sinuate and unusually longer just before attachment (one picture shows this clearly). I was initially expecting this to be an Entoloma, but the spores don’t match at all. Spore print is white and the ellipsoid spores have a distinct apiculus. 20 spore average is 5.3 × 3.4 microns, Qm = 1.57. See photomicrographs.

ITS region is identical to GenBank JN021003

Thanks Britney ..

yes maybe some Clitocybe, but I haven’t a clue which species. The gill “dropdown” is unlike anything I’ve seen.

Richard, I’m doubting Melanoleuca because the spores are not textured and definitely not amyloid.

I speculated the same thing …

however I doubt it’s Rhodocybe because there is NO texture to the spore surface. DIC would certainly show it.

I collected it due to my interest in Entolomas but now find myself quite stumped by this one. I’ll wait for other suggestions and as always there is a saved specimen of everything I post here.

why not Clitocybe?

I was really thinking this looked like an Entoloma too, with the white fuzz creeping up the stipe and how the gills looked. Maybe a Rhodocybe, they sometimes have really light prints, not sure if the spores look like Rhodocybe spores.
