in my opinion is this Marcelleina persoonii.
Greeting Peter.
Hi Yasan an Peter,
first: in contributions here I often miss any find-data. Yasan, unfortunately you do not tell us in what country, under what ecological circumstances you have found the species.
I agree with Peter that it should be Marcelleina. But - I do not see any ornament of the spores, so I am incecure of the species. If it is mediterraneous and the spores are really smooth (if not, M. Persoonii is likely) M. atroviolacea could be a solution. The color is usually darker there, but ... (??).
Regards from Lothar
there I must agree with Lothar.
Greeting Peter.
