Re : helotiales
Hello Ismail

although your pics are quite good I am not sure what you have. Perhaps Calycina languida? The spores would fit that species.

I cannot clearly see the ascus base which is reqeutred for a clear identification, also the iodine reaction of the ascus apex.

I assume there are no hairs at the margin?

Dear Zotto
Yes there are no hairs at the margin.
I reexamined I think so Calycina languida
thanks
