Hercospora tiliae?
Enrique Rubio, 06-05-2012 13:55
Enrique RubioDear 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

Re : Hercospora tiliae? réponse à Enrique Rubio
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

Re : Hercospora tiliae?
Merci, Paul.
J'avais des doutes parce que Dennis (British Asc.) dit et dessine 'spores not noticeably constricted'

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

Chris

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