Massariosphaeria on Fagus?
Amadej Trnkoczy, 18-04-2017 18:03
Amadej TrnkoczyHi to everyone,

Does this asco possibly belong to Massariosphaeria? Purple-red staining of wood, perithecia and septated spores somehow fit. However, substratum, relatively small spores and too few septa (compared to the descriptions of species I was able to find online) prevent me to find a reasonable fit to any species. Or it is something completely different? Any advice where to search or hepl in determination is gratefully appreciated.
