I have been trying to find an ID for these guys, and I gave up. It is so easy with some, but others just look like dozens of similar ones out there.
Based on a quick search, they look very similar to Xeromphalina campanella and to Gymnopilus sapineus. Probably a mushroom expert would be able to tell what mushroom species they are exactly.
Hmm.. I dont think its any of them. I see differences between them.
They are sticky thing, thats why I something juts give up :p
