Cosmospora sp
Christian Lechat, 13-06-2008 08:16
Christian LechatI would like to know your opinion about a collection of Cosmospora on 03.05.2008 in French Guiana, Saül, Sentier des Gros Arbres, on rotting bark, mixed with Neonectria jungneri, Haematonectria cf. haematococca, Cosmospora chaetopsinae-polyblastiae, Ophionectria trichospora, Viridispora alata and Bionectria sp.
There are several genera on this bark and it's difficult to study.
Only very minute ascomata of Cosmospora are isolated.

Cosmospora sp.:
Ascomata non stromatic,160-200µm hight and 100-130µm wide, red orange transluscent, asci and ascospores are visible through the wall. It’s difficult to make a section of perithecial wall but I was able to make one rather correct to measure it.
Perithecial wall 10-12µm wide made of a simple region of ellipsoid or elongate cells thick walled, asci clavate 55-70 x 12-14µm, ascospores 9,5-11 x 4,5-5µm, dark brown, becoming purple in KOH, striate.
Maybe have you an idea?
