Collection location: Jenkinson Lake, El Dorado Co., California, USA [Click for map]

Who: Ron Pastorino (Ronpast)

Specimen available

These were growing on disturbed soil (logged area) with only one tree nearby, a maple-like hardwood.
They were small with caps up to 3.8cm across.
They spore print was rusty brown and the elliptical spores were smooth, ~ 7.0-7.5 X 4.0-4.3 microns.
There was a trace of a fibrillose ring/cortina on a few of them.
The gills did turn a darker rusty brown in age and dried that color also.
KOH on the cap and stem surfaces turned a dark brown.
Except for the smooth elliptical spores, they do look Cortina-like. Hebeloma seems to be an an alternative?

Pholiota highlandensis does look good. I was thrown off a little by the spore color and by the fact they seemed to be growing on the ground. Dimitar questions whether those are really cystidia in my photos and there is a good chance that they are just random projections of loose hyphae.
I don’t know

…Pholiota highlandensis good but perhaps these pictures of a own finding in the end of May 2007 could interest you:


The shape and size of the spores and the figure of the cystidia correspond to P. highlandensis. Is the pileipellis of fresh fruitbodies slimy-sticky? It should be completely removeable as a translucent, rubbery membrane.
