on partially submerged wet hardwood
Ethan Crenson, 27-04-2022 17:28
Hello all,

Once again I find myself at a complete loss... This asco was found earlier this week on partially submerged, very wet decorticated hardwood in New York City. The cups are not much larger than 0.5 mm, and fringed by glassy hyaline hairs which cluster in bundles. The color of the hymenium is a smoky gray.


Ectal excipulum is brown with elements of textura globulosa/angularis. Hairs are septate, hyaline and tend to stick together in fascicles.


Asci IKI+, 62-78 x 8-9.5µm, croziers.


paraphyses filiform, about 1.25µm wide


Spores, fusiform to almost cylindrical, guttulate, 10.3-15.6 x 2.9-4.4µm ... average: 12.6 x 3.6µm ... Q: 3.5


Any ideas?


Many thanks in advance,
Ethan

Re : on partially submerged wet hardwood
I do not see the hairs glassy. Seems they are regularly agglutinated as teeth. Besides this, it reminds me of a Psilocistella (Hyaloscyphaceae s.l.), but that genus is little explored.
