Did not get enough characters on this one as was rushing back, note to self, always take more time to examine more carefully.
No identification made yet.
No interactions present.
Tarzetta cupularis seems to fit the species but it feel a bit daft saying that to an expert as your probably aware anyway.Habitat right too on soil
This would also be my suggestion.
Am certainly not an expert on these little cup like things. But do know there are rather a lot of them and might need spores or other structures to get very far.
Did go on some forays with a person who was an expert on these cup like fungi in general and he tended not to move more than a few metres while everyone else was walking round the woodland. there were just so many of the cup fungi and many of them were absolutely tiny so could easily spend a few hours just studying the small area and still not exhaust all the species there.
I've just been looking at some of the photos i took today and can see other tiny fungi in the background that I completely missed when taking the original picture, the more you look the more you see.
