another black bitunicate asco
Ethan Crenson, 05-03-2019 05:59
Found on the same branch on which fruited the Trichopeziza (?) in my previous posting (56603).  They are a cluster of tiny black fruiting bodies smaller than 1mm in diameter, rubbery (not carbonaceous) with a simple ostiole.  Asci 72-89 x 12.5-13.5µm, IKI- and bitunicate.  Spores light yellow to hyaline, 3-septate, some swollen above the central septation.  They measure 17-20 x 6-6.8µm. I did notice one part spore (picture 5), like the missing nose cone of rocket. Any ideas what this could be.

Thanks in advance,

Ethan

Re : another black bitunicate asco
Looks very much like Melanomma pulvis-pyrius; can't think of anything else.

Regards

Re : another black bitunicate asco
Chris,

Thank you for the suggestion.  I'm reading a description of M. pulvis-pyrius in Fungi of Switzerland.  The microscopic features seem to align fairly well with my collection.  But it is described as being "without a distinct pore".  Mine have a simple pore.  Then again, I have also seen certain photos on the web claiming to show M. pulvis-pyrius with what looks like a distinct pore. 

Do you know of any good literature I could acquire to read up on M. pulvis-pyrius?

Re : another black bitunicate asco
The attached from Munk's Danish Pyrenomycetes. Note he refers to a "porus" and shows one in the section. I suspect the pores in your images are rather large following spore discharge and subsequent abrasion. I'm sure that 's what you have - it's a very common and widestread species.

regards

Chris
