Dasyscyphella chrysotexta on indet. decorticate ha
A friend found this Orbilia growing on bark of hard wood lying on the ground in New York City.
Spores are somewhat curved, maybe not quite curved enough to be considered falcate. They may curve in two dimensions but it is difficult for me to tell with my equipment. They are acute, or nearly so at the tail end.
6.3-8.2 x 1.4-1.6µm
The spore body is 0.8-1.3µm long and in most cases a comparable width.
Ascus 36 x 3.5µm. It appears that at least some of the bottom spores have the spore body oriented downward.
Paraphyses are capitate, mammiform, with refractive exudate covering them. Width reaching about 4µm wide.
Is it possible to say which Orbilia this is?
Thanks!
Ethan
