nectrioid fungus on dung
Björn Wergen, 02-07-2013 11:25
Björn WergenHi there,

we have found a nectriaceous fungus growing on dung of Branta canadensis. It has some special features like striate, ellipsoid, 1septated spores, which become pale brown at maturity and a coarsely warted, orange red perithecia wall. The fruitbodies are up to 0,6mm broad and do not collapse after drying. Asci with visible apical structures and the perithecia wall reacts with CB orange-yellow. I did not test KOH since there are only 1 or 2 fruitbodies left for examination. So if you, Christian, are interested in this collection, just tell me and I will send it.

regards,
björn


edit: I have seen that my collegue has tested with KOH already (no reaction).

Hi Björn,
I think your fungus is the genus Neocosmospora = Haematonectria.
It could be Neocosmospora haematococca?


Thank you for your offer but your collection seems overmature.

Regards

Christian

Hi Christian,

yes, I think so too, here are photos of it with not overmatured spores:
