the black part is the unknown parasitized ascomycete with perithecia, parasitized by the red (which used to be called Nectria episphaeria but is now in a different genus) which also has perithecia.

and it has small holes. It’s possible that nectria and Cosmospora could co-exist? I see some few ring forms between the others.

the black surface have some higher dots, but that seems to be something under the “skin”.

and I looked for pyrenomycetes, but they are not much visible. I only see some higher dots and the nectriaceae is almost loosely attached.

on pyronemycetes?

the pictures remind me of Nectria / Cosmospora / Dialonectria episphaeria – which is common on Diatrype, Hypoxylon etc. fruit bodies.
