Bonjour,
Sur branche morte décortiquée de Berberis vulgaris en montagne (Valais, Suisse).
Ascospores : 19,5-25 x 6-9 µm, en moyenne 22 x 7 µm, brunes, à 3(4) cloisons, lisses.
Asques : cylindriques, bituniqués, contenant huit ascospores unisériées ou bisériées.
Pourrait-il s'agir de Thyridaria triseptata ?
Merci d'avance pour votre aide !
Andgelo

Re : Thyridaria sp.
Dear Andgelo,
I likely found the same species, also on Berberis vulgaris. Ascospores: approx. 21.2-24.3 x 6.5-8.6 µm, apparently always 3-septate.
I would put this in the vicinity of Lophiostoma quadrinucleatum. The ascospore size of our collections falls between L. quadrinucleatum and L. caespitosum. Interestingly, Holm & Holm mention collections from Berberis deviating from L. quadrinucleatum, but I have not seen the additional septa that they describe, and the ascospore length they give is still on the larger side.
So, my best guess would be that this is a distinct (undescribed?) species from the L. quadrinucleatum complex.
Best wishes,
Gernot
