Elisabeth StöckliBonsoir,Sur feuilles d'Osmunda regalis (Saulaie),
I hope you can help me with this one:
Habitat: On hymenium of old Stereum subtomentosum.
Macro: Perithecia seated on the host surface, with a very poorly developed yellow-orange subiculum. The host hymenium turns purple in infected parts. Individual perithecia with a diameter of around 0.2 mm and a height of around 0.25 mm with a whitish color when young and a purple color when mature. No colour change in KOH observed.
Micro: Asci IKI-, 80-95 x 4.5-5.5 um. Spores 9-11 x 3.5-4 um, 1-septate, finely verruculose. Perithecial wall of thick-walled roundish to angular cells (see photo).
Anamorph: Whitish tufts of conidiophores. Conidiophore morphology see photo. Conidia hyaline, one-celled, elliptic, 5-7 x 4-5.5 (mostly 6x4) um.
Many thanks for any suggestions
Stefan
I think this fungus is Sphaerostilbella berkeleyana with its asexual state gliocladium-like.

Christian
Yes, that should be it. Many thanks!
