What a great shot on a green drop!
Now comes the tricky part, to choose the right name. There are at least three names that belong in this group: fuscopurpureus, fagiphilus and alkalivirens (iocephalus is said to turn blue with KOH).
These three are possibly all the same species, and in that case fuscopurpureus is the name that should be used, but I don’t know.. Most pictures I have seen of fuscopurpureus, show strongly striate caps. This doesn’t, and it looks perfectly like the ones I have used to find here, usually on birch or alder leaves. I wish I knew what to call them. Mushroomexpert lists only alkalivirens, Funga Nordica only fuscopurpurea. I think I’d prefer to call this alkalivirens (in case they are different species after all). But it’s only an uneducated guess :-)

It does

on dried material, even the spores will turn green in KOH.

I have dried it so will have to try to check it when I get home, if it will work after being dried.

Not the same

as last year’s obs.
This looks like a Gymnopus. I’m not sure about the species, maybe something around fuscopurpurea (or whatever the name should be).
If it belongs to that group, cap and stem should be staining green with a drop of 5-10% KOH.
