Here is what I believe to be a Hymenoscyphus growing on very wet wood which was lying in mud and water in a New York park. They have a long stipe and convex hymenium. Trees nearby included Fagus, Quercus, Tsuga. My hunch is that the wood is hardwood.
Asci are IKI+ with croziers, 101-108 x 11.4-12.7µm.
Spores are fusiform, rounded at the ends with multiple guttules, occasionally 1-septate, 14.1-21.6 x 4.1-6.3µm.
Paraphyses branch, with oil content (I think).
The stipe excipulum is textura prismatica, and there is brown pigment among the cells. The medulliary excipulum is textura angularis verging on textura globulosa.
Long ago on this forum I posted something similar (but with a shorter stipe) which Zotto suggested might be Hymenoscyphus varicosporoides. Could this be that as well?
Thanks in advance,
Ethan
