I have looked at descriptions and other pictures and do not beleive that the yellow-capped earleae on MO are ID:d correctly… :-/

After accessing collections on MO of G. earliae

stipes, cap color, and gills do not match.

has identified many fungi.

Perhaps best to ask her about her collections?

Just added two photos of dried collection. The gills are very red-brown sometimes toning to black, as dried. I wondered about the true color of the stipe: dark brown area near stipe base may be caused by handling, but not area near cap.

Cap color has not been affected by handling, just by the drying process.

Fresh and dried color does not seem to match most identified collections of Gymnopus. Most Gymnopus appears to have cream-colored caps. These are cream colored only in immature specimes.

Well,

the Burke herbarium in Washington has two collections labeled Collybia verna from Oregon (Portland, Multnomah, collected by L. Norvell)
- and two from Washington. The annotations on the Washington collections say “not necessarily correct name” :-)

Gill color today almost black as dried.

Not sure if G. vernus is found in Oregon Irene. Interesting possibility, isn’t it?

doesn’t look right for ocior – but G. vernus has brownish gills. Do you have them in Oregon?
