Dactylospora stygia?
Ethan Crenson, 19-01-2017 16:45
Hello all,

New York City, Prospect Park, Brooklyn on rotted hardwood.  Spores are brown, 1-septate, ellipsoid and slightly cinched at the septation.  15 - 22um by 5 - 5.5um.  Asci I have measured are about 98 - 15 um.  All photos are mounted in water. 

Thanks in advance!

Re : Dactylospora stygia?
Yes, I think this is very typical D. stygia.
I suppose you are aware of the strong IKI reaction of the asci.

Re : Dactylospora stygia?
Thank you for your response, Zotto!  I had not come across this species before, so I was not aware of the strong IKI reaction.  I will check it out.
