Why Leucocoprinus? With such Leucoagaricus americanus-like coloration, the thick annulus, the pink/brick-red disc which dissipates out toward the margin, I would have never guessed Leucocoprinus. They almost look as though they might just bruise reddish orange on contact. Is it the substrate? Something else?

I see nothing to indicate white spores “(these spores are white)”. Not much to indicate any spore color. Cap has only recently separated from annulus.

I was specifically thinking of one species in Arora, C. alnivorus. I started the comment with Lignicolous Coprinopsis because that is the exception rather than the rule. Having grown up on a ryegrass farm in Oregon, I’ve seen millions of small Coprinus (Coprinopsis) growing on straw and/or hay left out to compost.

this isn’t Coprinopsis

(these spores are white), nor is the entire genus “usually associated with Alder” in America. substrates and associations vary widely.

Lignicolous Coprinopsis.

Unsure what species in Panama, Eduardo. In America, usually associated with Alder (Alunus).
