Arnold BüschlenHallo, ich suche zu Cosmospora aurantiicola Lite
Disc yellowish, up to 2 mm., stalk whitish, smooth and slender.
Asci 142-160 x 12.8-14.4 microns, IKI+.
Ascospores 40-48.7 x 4.5-5.8 microns.
Paraphyses filled with refractive contents.
Ectal excipulum, parallel, thick-wall, gelatinous hyphae.
Is this a Crocireas?
I couldn't identify by Carpenter's monograph.
Best wishes,
Kutsuna
This is certainly a Hymenoscyphus in which the excipular cells are also somewhat gelatinized. Such strongly heteropolar spores are unknown in Crocicreas or Cyathicula.
This find is interesting, it reminds me of the N-American Hymenoscyphus dearnessii, a variant of which is known from Europe, here exclusively on Fallopia (Reynoutria). But the spores are not as big as you say, also they should have bristles at the ends.
Have you more microphotos? Ascus croziers? In which part of thw wordl did you collect, and what could the substrate be?
Zotto
Thank you for your reply.
This disco collected in bush near beech forest, Tottori, Japan, 22.Sept.2012.
Substrate uncertain herbaceous stem, I think Polygonaceae.
I have no more microphotos, but I couldn't observe coriziers and bristles.

This sounds like a new species.
