Observation 302931: Mycena (Pers.) Roussel

Notes:
Growing scattered in hardwood leaf litter. Abundant. Odor indistinct. Did not appear to be hygrophanous. Cap edges discoloring brown. Cheilocystidia abundant, smooth and fusoid-ventricose. Basidia observer were 2-sterigmate. Spores smooth and inamyloid or possibly very weakly amyloid.

Couldn’t get a good species level-ID

I keyed this out in “North American Species of Mycena” and on Mushroom Expert and the closest I got was M. pectinata, but that species in the sense of Smith probably represents several different species which were not Murrill’s original species according to Maas Geesteranus in “Mycenas of the Northern Hemisphere II”.
