Notes:
This tripartite/quadripartite system seems to be found wherever certain Fomes/Fomitopsis species grow and, eventually, rot. I have now seen this or something like it in the PNW, upstate New York and the Sierras. It involves said polypore substrate, Hypocrea (aff.?) pulvinata, and one or more uniperitheciate sordariomycetes with long, slender ostiolar necks. John Plischke had species level IDs for what he believed to be two species co-occurring on this materialMelanospora lagenaria and Ophiostoma polyporicola — at least one of which may be present in this observation as well. The Melanospora is supposed to have paler, oranger necks, as opposed to the darker Ophiostoma. If both are present in this specimen, I can’t tell them apart. Maybe this is neither! Perhaps John will weigh in himself at some point.

Joshua Birkebak (Shua) was given a piece to culture before we had any names beyond guesses at family for the tiny ascos. Awaiting word back on what he finds.

I found something similar to this growing on a Fomitopsis pini-Canadensis fruitbody in the pnw. It wss growing out of the rotting pore surface.

It is a chain of saprophytes!

Danny, some of your photos in this posting are fantastic!
Thanks for posting them. A&O Ceska

courtesy of Mr. Björn Wergen’s unstoppable identification skills, we have at least one 100% bonafide name for one of the fungi seen here; Melanospora lagenaria. The extent to which Ophiostoma polyporicola is also present has not been confirmed as of yet. I’m making M. lagenaria the focus of the observation on account of it being what both Björn and I decided to scope and photograph.
