ochraceous Hypomyces in white Subikulum
Andreas Gminder, 27-12-2017 18:04
Andreas Gminder

Hello,


I have an ochraceous Hypomyces species growing in a dense white subiculum directly on rotten wood (no hint to any fungal host to be seen)


The spores are comperatively small and break into two pieces already in the ascus, and they are (nearly?) smooth and have an appendix on each end.


The broken triangular part-spore measures appr. 3,5-4,5 x 2,2-2,8 µm, the whole spore including appendices and the gap between the part-spores reaches nearly 10 µm.


I know that there is a key of Hypomyces in a FMBDS-journal, but I don't have it with me.


Does anyone know this Hypomyces species - is the name H. ochraceous correct?


best regards,
Andreas

Viele Grüße von Lothar
