Hello

I have found ascomycete with the following characteristics:
Substrate: I think it might be leaf Cornus
Immersed-erumpent pseudothecia, approximate size of 150um.
It grows abundantly on the whole surface.
Asci: 40-62 x 10-12um.
I have found anamorph on the same pseudothecia.


I think it can be a species of Guignardia
Thanks in advance. Greetings.
