Recognized by sight: small, delicate mushrooms under oak.

Recognized by sight: This is likely the same as observation 33397, but I guess we will never know for sure.
47% (2)
Recognized by sight
56% (1)
Recognized by sight: Either marescibilis var virginea or the similar undescribed one, I believe.
These are called “Coprinopsis/Psathyrella white” in “Mushrooms of the Redwood Coast”
They seem quite common in the East Bay hills in my limited experience.

I was trying to be as circumspect as I could. Habitat I could do…oak leaf litter.

Just let it go…there’s plenty more fungal meat to sink your teeth into! Here comes some more now…

Aw, com’on here…
