Cosmospora?
Bernard Declercq, 28-09-2010 22:47
Bernard DeclercqGood evening,
I recently collected Phomatospora luteotingens J. Fourn. & C. Lechat in the Belgian Ardenns, but on the same submerged branch Nectria-like semi-immersed ascomata, 0,3 mm diam. by 0,5 mm high, dark red, glabrous, laterally collapsing, occured. Spores are broadly ellipsoid, verruculose, yellow-brown, 1-septate, 11,5-15,5(-17)*6-7,5(-9) µm, filled with guttules. This could be a Cosmospora but in the key of Rossman & al. 1999 I did not find any dark red semi-immersed species. Any idea?
In annex, ascomata and spores.
Thanks in advance,
Bernard

Re:Cosmospora?
Hi Bernard,
could you please send us a macrophoto as well as a vertical section of perithecium? because maybe your fungus is not a Cosmospora. What is the thickness of the ascomatal wall?, moreover, asexual state is required to determinate a species of the genus Cosmospora but, at first we could see if it is Cosmospora, even without knowing its anamorph.
All the best,
Christian

Re : Cosmospora?
I think it is closely related to this finding:
