Caution: Do NOT use iSpot to identify fungi to eat!
Some fungi are very poisonous so a mistaken ID could have serious consequences.
No interactions present.
Never heard of Coprinarius. Maybe it takes time for these names to filter through. Looks like Parasola to me.
The name has changed for some ink caps probably C.leiocephalus but these small ones are difficult to separate without microscopy
I have not heard of Coprinarius replacing Parasola, and the British Mycological Society doesn't list this change, but perhaps both they and I are out of date?
I had to guess, which I proably shouldn't, I would say I suspect this is Parasola galericuliformis (as understood in the UK). But cannot tell from the photograph.
