Hymenoscyphus fructigenus?
Ethan Crenson, 26-10-2017 07:03
Eastern US, New York. On nuts of Fagus in the mud of a creek bed. White stipitate cups. The largest cup is 2mm wide. Asci are 72-115 by 10-12.5µm. Very weakly IKI+, if at all. Spores 12.5-14.5 by 5-6.5µm with several oil droplets. Occasionally septate, I think. Paraphyses septate, enlarged at the ends, about 2.5-5µm. This resembles Hymenoscyphus fructigenus, but I think the spore and ascus sizes are a little small and the paraphyses are a bit large. Also, the asci aren't reliably amyloid. Could this be something other than Hymenoscyphus fructigenus?

Re : Hymenoscyphus fructigenus?
Completely impossible for a relationship with H. fructigenus. This one has rather short homopolar sporres and I am not even certain with the genus.

You should try better photos of the ascus apex, perhaps the amyloidity and the shape of the apical ring become more clear.

What you have is perhaps Hymenoscyphus varicosporoides = Cudoniella indica = Hymenosc. "calycinoides", a species with an interesting semiaquatic anamorph.
