Bonjour,je serais heureux d'avoir votre avis sur c
Hi to all
I need your help again with this fungus growing on wet wood of Erica arborea at 1400 m of altitude. The superficial, sessile, gregarious, roundish, rough, papillate, ostiolate,pseudothecia are 0.4-0.8 microns in diam. and they grew on a sparse subiculum of brownish hyphae. Their walls are carbonaceous and the inner wall of the young stromata have ochraceous or reddish pigments that don't exist around the ostiole as in B. schiedermayeriana. The 8-spored asc are bitunicate and shortly stipitate. Pseudoparaphyses trabeculate. Mature ascospores are brownish, 1 septate (or with 2 more secondary septa), no appendages, no sheath.
I think this fungus could belongs to the genus Byssosphaeria and maybe this is B. salebrosa. What do you think?
Many thanks again
I agree. Macroscopically and microscopically.
It could be the first european record !
Again an incredible fungus found by you.
