Hello,
This asco was found on the same wood as my previous post (Hymenoscypha varicosporoides) which was lying in mud and water in a New York park. The wood was probably hardwood. There was Fagus, Quercus and Tsuga nearby.
They are gelatinous and pulvinate. When found they were off-white, the largest about 1cm.
Spores are thick walled, have two large guttules. They measure:
19.4-20.3 x 11-12.8µm
Me: 19.8 x 12.0µm
Q: 1.56-1.76
Qe: 1.64
N=14
Me: 19.8 x 12.0µm
Q: 1.56-1.76
Qe: 1.64
N=14
The asci are IKI+ along nearly the entire length.
Paraphyses are enlarged at the ends, reaching about 4µm. They contain oil content, however, the typical brown pigment is mostly absent. I left it in the refrigerator to mature a bit and the apothecia turned a tan color and the paraphyses became slightly yellow-brown.
Excipular elements have a textura globulosa and some cells have finger-like protrusions.
Maybe this lack of pigment is typical of immature specimens? Could this be something else?
Ethan
