Observation 275744: Coprinellus P. Karst.

On burned wood and with greenery at third year burn, in exposed, devastated landscape.

I was pretty sure this was C. angulata, until I looked at the spores!

Also somewhat similar to C. impatiens.

Young caps were an orangy color.


Small grouping in third year burn.
spores dark brown in water. elliptical to pip shaped to bean shaped. 1000×.
