Hello everybody,

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

Re : Nectria s.l.
Hi,
I think this fungus is Sphaerostilbella berkeleyana with its asexual state gliocladium-like.

Regards,
Christian
