Observation 202119: Psathyrella spadicea group

When: 2015-03-30

Collection location: Mormon Emigrant Trail, El Dorado Co., California, USA [Click for map]

Who: Ron Pastorino (Ronpast)

Specimen available

Growing cespitose on the ground in mixed woods, mostly Doug fir.
Caps up to 5.0 cm across. Whitish grainy material on caps likely from some other source as most of what I found had similar material on caps.
No distinct odor.
Could not get a spore print but spores brownish based on deposits on lower caps and microscopic features.
Spores ~ 7.9-8.8 X 4.2-4.8 microns, elongate and smooth to sl. rough.
Gill cystidia plentiful especially Pleurocystia, ~ 40-50 X 12-20 microns, broadly fusiform to mucronate, thick-walled near apices and some with encrustations.
Hebeloma may not be the only possibility.

something in that group although the scaly stipes seem a little off.
The "Rhodopsathyrella " genus appears to be new to MO, and I don’t know anything about it. Your call.
