Hola a todos. Pongo unas fotos de una Peziza que
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
Maren
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.
