Observation 161291: Marasmiellus Murrill

These were growing on woody debris including twigs in a mixed woods of Madrone, Live oak and others.
Caps were up to 10 mm across and minutely hairy, which can be seen better on “Full Size”. Stipes were also somewhat fibrous and fairly tough.
Could not get a spore print and I’m not sure if they were amyloid or not.
The few spores I was able to see were ~ 10.8-12.9 X 4.8-5.1 microns and lacrymoid.
The distinctive whitish cap and contrasting yellow, wide-spaced gills made me confident of a quick ID. So far no luck….?!?

Definitely a Marasmiellus

I just sent Ron sequence results which show that it’s a Marasmiellus, but a weak match for the known species in GenBank.

Everything about this except for the yellow color suggests Marasmiellus (including spore morphology).

I wonder if this is a variant/species where the gills turn yellow instead of the normal pink blushing in age that we see in Marasmiellus.

Nice find!

cool as hell!

Well, this is different. I’ve never seen it before.
