Re : unknown on horse dung
Hi, Sven,

your fungus looks "calosphaerioid", i.e. it might belong to Calosphaeriales or Togniniales although I don't have a more specific name to suggest without digging further into the literature. Maybe one has to consider that its growth on dung is only facultative...

Best wishes,
Gernot

Re : unknown on horse dung
Hello Gernot,

thanks for your help! B. Wergen has called this fungus as Calosphaeria pulchella. Apparently the fungus has been mistaken in the substrate.

Greetings Sven
