Pyrenomycete from coniferous wood




I have this nice pyrenomycete with aggregated black immersed perithecia with and protruding ostioles from Picea (Pinus?) wood. Asci cylindrical, thin-walled, lacks apical apparatus, inamyloid, p. sp. 40-50 x 4-5 mym, not floating like in Diaporthe. Ascospores 8 per ascus, obliquely uniseriate, 7-8 x 2-3 mym, cylindrical, two-celled with central septum, rounded ends, greyish, with 2 small oil drops. Paraphyses simple, longer than asci, ca 1,5 mym broad. Peridium medium brown, of rounded cells ca 4 mym in diameter. Thankful for suggestions.

  1. does twin-walled refer to a bitunicate situation or is it a typo for thin-walled? :) (a picture would be nice)

  4. Have you tried to raise the question at AscoFrance ? It is an excellent place to get helt with Asco-identifications . . .

  5. Yes but no luck yet. I had also misinterpreted the fungus somewhat. It had immersed, bigger, oval, perithecia. It´s weird but I didnt see them at first (didnt dig for them) but did find spores and hymenium from the upper protruding parts! Text now changed in both places.

    By the way, I wanted to ask you about costs and tips of focus stacking stuff... I am going to buy the equipment needed...

  6. On more by-the-way, tried to find a name for the "läcker" yellow pyreno recently posted there but failed, looks a little like a Cucurbitaria but yellow and spores without a waist. Wouldn´t Thomas know?
