Recognized by sight: M. epipterygia was confirmed via the Brian Perry key from his California mycena thesis.
This mycena is in the hygrocyboid section and nivicola/griseoviridis group can be eliminated. Perhaps there are cryptic species or this needs a new name in the California sense, but I see no suggestion of cryptic species in either the aforementioned key, which I consider to be the authoritative source for California Mycena taxa, or Mushrooms of the Redwood Coast, which is the most recent field guide I have for the region. If there are any varieties elevated to species rank, or new taxa proposed/described, then I will update this accordingly. Until then, I feel certain that it is one of the varieties/forms within M. epipterygia.

“Mycena epipterygia” is accurate for any subspecies/variety/form within M. epipterygia.

Random question

Does it not encompass the taxa M. Epipterygia var. such and such if one does not include the “group” tag? Sorry if this is a dumb question
