Re : Unknown pyrenomycete
It does not distinguish well, but can you be seeking to Kernia? Have you seen hair?

Re : Unknown pyrenomycete
Hi Joop..
That looks like it might be Mycoarachis inversa. It seems to be most common in dry regions, which hardly describes The Netherlands. However, the similar species Nigrosabulum globosum is also characteristic of dung in dry regions yet was common on my collections of horse dung from Sable Island, Canada and Shackleford Bank, USA, both sand dune areas in very humid climates.
The attached paper, although old and out of date, may be some help.
