Hi everybody,i keep finding this Pyrenopeziza species on various herbaceous stems. This is on Impatiens sp.
Apothecia 0,6 mm, with hyalin margin hairs up to 27 x 5 µm. Spores hyalin, Oil 0-1, (7,5-10) 8,9x2 µm, Asci with croziers, 47-58 x 5- 6 µm, IKL blue. Paraphyses cylindrical, with some round guttules, up to 3 µm wide, KOH negative.
I thought of P. pulveracea, but I'm not sure.
Thank you
Regards

I'm also not convinced it's Pyrenopeziza pulveracea. I would have thought the macromorphology and dark-pigmentation of Pyrenopeziza pulveracea is quite stable.
Maybe it's similar to one of Ingo Wagner's Pyrenopeziza species from Impatiens? http://asco-sonneberg.de/pages/gallery/substrat-impatiens-glandulifera-1007259511.php . I think No. 9 looks macroscopically similar, but I can't see any photomicrographs associated with these collections.
It's not one I've sequenced, and I can't find any clue in any studies of Impatiens or in GenBank as to what it could be DNA-wise.
Cheers,
Brian
thank you, I thought also that my species is too light for P. pulveracea. Yes, Ingos species looks like mine. My substrate is Impatiens noli-tangere.
.... of course you are right, I didn't mean Pyrenomycetes but Pyrenopeziza, I've corrected it.
Thank you.
