Observation 339276: Gymnopilus P. Karst.

When: 2018-10-13

Collection location: Frazier Falls, Plumas National Forest, Plumas Co., California, USA [Click for map]

Who: Pgrunow

No specimen available

Stem and underside bright medium yellow at collection, darkened to color shown. Stump was either pine or fir. Brown fibrils on stipe, cortina-like. No staining, except possibly turning bright yellow in places.
Taste bitter, slightly acrid. Cap width about 10 cm at broadest point.
The base was enlarged slightly when attached to the tree.
It would appear that the stipe is too fibrillose for the luteofolius and thiersii groups. Perhaps there had been a partial veil that is mostly gone?

From the SVIMS key, I get cap not small> no blue/green
If I consider this to have no veil, then >on wood= echinulisporus or liquiritiae group. This is not in the liquiritiae group, and the one observation of echinulisporus on this site fits this poorly.

Possibly the same as 3284
