Didymosphaeriaceae (?) on Ulmus branch
Enrique Rubio, 08-02-2017 20:38
Enrique RubioHi again
I have found on fallen branches broken by the wind, these small (500-870 microns high, up to 100 microns broad), pyriform, subepidermial or inmersed on the wood, somewhat glabrous pseudothecia, solitary or arranged in fused groups, on Ulmus minor. The fungus seems to be xerophilous, because only the fall of the branches allowed me to see it.
The asci I think are not unitunicate, although that is not easy for me, with a variable numeber of ascospores (often 8). Pseudoparaphyses narrowly trabeculate. Ascospores yellowish, brownish, brownish-black, uniseptate (secondarily septate at maturity), heteromorphic, with clearly longitudinaly striate walls, sometimes sub-reticulate. Pseudothecial inner walls with hyaline prismatic or roundish cells.
I think could be near to Didymosphaeria, because the pseudothecia are not arranged in Valsoid-type as in the Valsariales.
Have you some idea for me?
Many thanks again

Re : Didymosphaeriaceae (?) on Ulmus branch
Salut Enrique,

A moins d'une révision plus récente que la documentation en ma possession, ce spécimen semble convenir pour Didymosphaeria massarioides Saccardo & Bruneau.
