Polysporous ascomycete
Gernot Friebes,

this puzzling species was handed to me. It grows on decorticated, dry, sun-exposed wood of a fallen oak tree. The ascomata are very variable, sometimes +- globose and solitary, other times clumped together or somewhat immersed in the wood. The asci are filled with numerous tiny, hyaline, ellipsoid ascospores which measure just about 2 x 1 µm. The asci appear to be bitunicate, they are widest close to the base and have a short but distinct stipe. Interestingly, they show a bluish reaction to KOH+IKI. We are thankful for any ideas!
Best wishes,
Gernot

Re : Polysporous ascomycete
Ascospores or microconidias ?

Re : Polysporous ascomycete
Hi Alain,
the person who collected this fungus has only observed these tiny spores but I'm not sure... I haven't studied the material thoroughly myself yet. Do you have any idea if we assume these are in fact conidia?
Best wishes,
Gernot

Re : Polysporous ascomycete
Not idea for the moment, but one can have fungi for which it's possible (in Nectriaceae family for example).
Your fungus macroscopically looks like Bertia.

Re : Polysporous ascomycete
Hi,
this is just a quick update for anyone interested in this fungus. I was able to identify it as Moristroma quercinum, or at least it seems to be this species based on gross morphology and ecology. See here for more information: https://www.researchgate.net/publication/226350012_New_species_of_Moristroma_Ascomycetes_and_phylogenetic_position_of_the_genus

Re : Polysporous ascomycete
thanks Gernot for this information.
I think I already came across a very similar fungus in the past but I had no clue about its systematic position. Bjorn's paper is excellent and leaves no doubt about the identification.
Great!
