No specimen available

Name changed from Coprinus plicatilis to Coprinellus silvaticus based on color photos in both Phillips and Pacioni. After reading Flora Agaricina Neerlandica Vol 6, it could be any of several similar looking species in this group. Color photos of too many species of Coprinus can be seen at the web site of Kees Uljé.

I use veil characteristics

Tom Volk gives a nice summary of the macroscopic differences. I pretty much go by the nature of the universal veil except for Coprinus sensu stricto which pretty much all look like Shaggy Manes. I’d be curious to know what the thesis you mentioned says to use.

I’m still using Coprinus because the characters used for the breakup into other genera are still not clear to me. Using Matthew Keirle’s thesis on Coprinus leaves me puzzled. About 5 years ago Scott Redhead published an article in McIlvainea, Vol 14 (2):5-14, that lists the reasons for splitting the genus, but not the field characters necessary to recognize the new genera.
I used Arora to ID this Coprinus and would be happy to improve on the name for it. After a long day in the mountains, it was a “best fit”, not a perfect fit!

Why do you use Coprinus?

I’m curious why you used the genus Coprinus for this? It looks like a Coprinellus to me, but if the species epithet is right then it should be Parasola plicatilis. However, it sure looks like there are some granular veil remnants.
