some people do not agree with IF.

Yeah, the new name doesn’t change what it is…

Just what we call it. MO is my way of keeping up with the changing names. Actually, there seems to be some difference of opinion about the genus for Lepiota/Echinoderma aspera/asperum.

Most similar Lepiotas are smaller with thin flesh. But large examples of Lepiota clypeolaria can look pretty similar to aspera/asperum. I think obs 180251 represents clypeolaria. The ones in that collection were quite large.

The ring on asperum is typically more well-developed and persistent than with clypeolaria. Asperum is more thick-fleshed/robust, like the ones in this obs (198767).

I’m happy I named it Lepiota aspera
