Claussenomyces sp.?
Bigelow Tom, 08-07-2017 02:06
I found what I think might be a species of Claussenomyces with its Dendrostilbella synnematous anamorph on wet, very well-rotted Tsuga canadensis in Fahnestock State Park, New York on July 3, 2017. The largest of the discomycetous fruiting bodies in the first image is 3mm. They are gelatinous. The synnemata are about 3mm tall, coated in a green slime that evaporates/disappears very quickly as they are exposed to air/light. I find the synnemata several times a year, year-round, always on well-rotted, wet wood of all sorts: Betula sp., Fagus grandifolia, Quercus sp., Pinus strobus, Tsuga canadensis, but have never seen the associated discomycete until this one. We were unable to find loose spores in the Claussenomyces-like fruiting bodies, only seeing them in a single ascus. They were small, about 2x3 microns and they appear to not be septate. Am I on the right track? Might they be something else? Any suggestions/guidance be would be most welcome! Thanks, Tom

Re : Claussenomyces sp.?
Dear Tom

interesting observation but more data are necesary to help here.

You say the largest apos are 3 mm. With a razor blade you should easily make a median section to show the excipulu. Is it brown or hyaline? Cell shape? Where is it gelatinous?

Did you test Lugol for the ascus apex?

Do you have images of the anamorph too?

At present I have no idea for a genus.
