Tom SchrierHi all,We found picnidia on Protoparmeliopsis mur
I am hoping someone will have some insight into this interesting asexual fungus I found on hardwood (probably oak) in a New York City park yesterday. It appears to be erumpent, gelatinous acervuli which bristle with conidia on the surface. When cut the solid interior of the acervuli are black (when fresh) and gelatinous. As they age and hollow out they become tan.
The conidia are brown, very thick walled, multi-septate, and shaped like bowling pins. Sometimes they are curved. There are wavy striations in the flanks of the conidiospores. I am reminded of the conidiospores of Helminthosporium velutinum, but of course that does not produce acervuli like this.
I have seen some discussion/images of the genus Coryneum which seems similar. Can anyone point me in the right direction?
Thanks!
Ethan
