In a moisture chamber with dung of Nyctereutes procyonoides there developed after four weeks a white mould in one corner. Now two weeks later there are some dark cleistothecia developing on top of the mould/subiculum. The size is about half a mm.

The asci are thin-walled and looong, up to 200 µm, IKI-. Most of them are eight-spored but many six-spored with one spore aborted. The spores are (sub)globose, on average 12.3 x 11.1 µm, hyaline (wrong colour balance in the large water spore images). The spore wall is two layered, calyptrate, in water the surface looks ornamented with short crests but in unheated CB the spores are perfectly smooth. The outer layer is cyanophilous. The spores also look slightly dextrinoid in IKI.

In another corner of the culture (without mould) there were some Preussia funiculata, which externally look exactly the same. Also the ascus length matches but the spores are, of course, completely different.

I have no idea what animal this is. Anyone?
