I have no idea what it is. It does not concern 4-spored genera like Boothiella (spore length > 10 um) and Arxiomyces (ascomata dark and beaked).
Does anybody has a suggestion what this could be?
Thanks in advance, Eduard

Re : Pale 4-spored pyrenomycete
Further study has revealed that the collection best matches the characteristics of the genus Pseudallescheria (see Guarro 2012, Soil Ascomycetes): cleistothecium, textura epidermoidea, brown one-celled spores with a germ pore at each end. However, this genus is only known with 8-spored asci. The main question is what is the taxonomic significance of the spore number/ ascus? Does it depend on environmental conditions?

Re : Pale 4-spored pyrenomycete
Finally this fungus has got a scientific name thanks to two German collections and the Westerdijk Institute (former CBS): Paramicrothecium sambuci.
(sheet 1329, pages 262-263).
