that the brown in the upper left of the frame is spore deposit, is there? the most mature of them are still shock white, so I’m inclined to think it’s just decay. I’m not seeing stipes either, so Marasmiellus is on hold. An all-white, Marasmielloid Resupinatus? Or maybe something similar to this:


which is still being called Marasmius/Marasmiellus, stipe or none.

note: Flora Agaricina Neerlandica 3 says Marasmiellus lateralis is the only species of the genus in Europe with a sessile, pleurotoid basidiocarp. but I can find no images of it.

Yeah, at first I didn’t think they had any stipe either, but when I looked closer at some of the individuals (granted, there is no high definition photo), it appeared that the stipe might be obscured by the mushrooms position. Though if you don’t see any stipe either, I’ll concede.

not Marasmiellus

Marasmiellus candidus has caps that are centrally stiped – this mushroom does not even have stipes, and the caps are excentrically attached to the substrate.
I have no idea what it could be, but do know that it is not Marasmiellus candidus.
