Hercospora tiliae?

Dear friends:Thsi fungus forms up to 1.5 mm stromata just beneath the bark of Tilia cordata rotten branches together with pseudothecia of Splanchnonema ampullaceum.
The valsoid 1-8 perithecia are placed inside a white entostroma and their ostioles are very inconspicuous.
I think could be Hercospora tiliae or a close species of this genus.
What do you think?
Many thanks in advance
Enrique

Bonjour Enrique,
Oui pas de problème pour Hercospora tiliae,cette espèce est très commune sur Tilia
et très souvent en mélange avec S.ampullaceum.
Amicalement Paul LEROY

Merci, Paul.

Re : Hercospora tiliae?
Hello Enrique
the illustration in Dennis shows thick-walled empty-celled spores - perhaps this is an issue of "vital taxonomy" and RWGD was working only with herbarium material?
best wishes

Re : Hercospora tiliae?
It seems Dennis only works with dried material. Thank you Chris. I think it's a good possibility...
