G. aquosus

is described from Europe, yes.
I found the study (by Vilgalys, Mycologia 83 (6)) that indicated interfertility between subsulphureus and alpinus (but none of them with aquosus).
G. subsulphureus was then proposed to be a subspecies of alpinus. Very strange..

Is Gymnopus aquosa a European species?

I can’t find it in Roy Halling’s key. We also get a similar species with yellow gills which is probably G. subsulphureus. I understand that it is mating compatible with the European G. alpina which reportedly looks very different.
