Lepista ZacariasHello everyone, Does any one know of any literatu

Found on cow dung.
Fruitbody ball shaped, diameter 155-166 um, at maturity it will develope a cap.
It contains spore clusters of 8 spores each.
Spores: 5.3-5.45x2.4-2.6 um
Michel.
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The attached paper, although old and out of date, may be some help.

Thank you very much for the information David.
