Observation 58238: Hemimycena lactea (Pers.) Singer

When: 2010-11-02

Collection location: Yosemite National Park, California, USA [Click for map]

Who: Ron Pastorino (Ronpast)

Specimen available

Collection #1516 for the Yosemite Fungal Survey.
These were plentiful in the areas I was collecting but small and so far difficult for me to ID to species.
The few spores that I obtained from a print seemed white, non-amyloid, and pip-shaped, ~ 7-9 X 3-4 microns.

my original guess of Mycena delicatella aka Hemimycena delicatella which does have adnexed to almost free gills;
> 617a Gills free or adnate, narrow; cap often over 0.5 cm; typically on twigs or needle debris; Hemimycena delicatella

Mycena delicatella (Peck) A.H. Sm. is a synonym.>

The spores are fairly close in size also.

I couldn’t find a hemimycena that matched your spore
size and lack of decurrent gills.
I thought of alboleptonia sericella but that has different spores.

Good luck Ron!

Not Hemimycena

Gills are not decurrant.
