Bernard DeclercqHi to all,

I need your help for the determination of an old collection on a corticated branch of Prunus serotina:
Ascomata immersed, about 0,5 mm diam., in small groups, with elongated collectively erumpent beaks. Asci bitunicate, cylindrical, 8-spored, spores uniseriate, 130-150x10-12 µm. Spores ellipsoid, 15-21x7-10,5 µm, with (2)3(5) traverse septa and 1-3 segments with a diagonal septum, guttulate, smooth, pale olivaceous brown but with dark brown septa.
Your suggestions are welcome.

Bernard

Hi Bernard,

this is Dyrithium lividum (in ascofrance, look also at Thyridium lividum).
