Collection location: Sawmill Mountain Road, Tuolumne Co., California, USA [Click for map]

Who: Ron Pastorino (Ronpast)

Specimen available

These were growing under small pines at ~ 4000 Ft.
Caps were up to 5.3 cm across.
Could not get a spore print but the spores were ~ 7.9-10.0 X 5.1-6.5 microns and moderately to strongly rough. Q(ave.) = 1.47.
KOH on the cap was a dark reddish brown.
Cortinarius croceus is a good possibility but the spores seem a little too large & rough and maybe the coloring is a little too dark?
I’m going with C. croceus as it seems to be considered the local current name for this common Dermocybe.

Even without access to the description, I like it better than C. croceus.
