Champignon imparfait sur écorce de branche morte de chêne (Quercus robur)
Bernard CLESSE, 17-02-2017 21:35
Bernard CLESSEBonsoir à tous,

Trouvé récemment ce champignon imparfait sur écorce de branche morte de chêne, au sol.

a) conidiophores septés, effilés vers le sommet, souvent incrustés en surface
b) conidies ovales à subglobuleuses, avec une petite guttule : 2,5x2
c) cléistothèces comprenant de gros cristaux 

Une idée ?

Bernard

Cher Bernard,
This seems to be something like the fungus that I described once as Chaunopycnis alba, but this  did not have closed fruitbodies with a distinct peridium as you illustrate here.  Chaunopycniis has recently been merged with Tolypocladium by Quandt et al. in IMA Fungus 5: 126, 2014. Otherwise I rather think that the fruitbodies you ilustrate are just immature ascomata of something.
Best regards   Walter

Hello Bernard,
Perhaps consider the basidio genus Stigmatolemma. I have collected something very like this on a few occasions.
Regards,
