Hi to everybodyThese thiny, blackish pseudothecia
Pyrenomycete with hyaline thickwalled hairs

Hi everybody,I found a few perithecia (diameter 0,35 mm) on Sambucus nigra without bark. Spores, hyaline, big 34-46 x 7,5-10,1 µm, becoming 1-septate. Hairs thickwalled (up to 365 µm long and 11 µm wide) with refractive walls. Asci 115-130 x 12-20 µm, IKL negative.
I thought first of an Echinosphaeria sp., but I understand that this genus has brown setae. Maybe a Trichosphaeria?
Regards, Maren

Hi again,
I found some immature perethecia on another stick. There are accompanying conidia.

Re : Pyrenomycete with hyaline thickwalled hairs
Hi Maren,
I think your fungus is related to the Helminthosphaeria stuppea complex (se Miller et al., 2014, Mycologia 106: 505-524), but ascospore size does not fit.
Could you check under the stereomicroscope if the ostiole is surrounded by 3-4 tubercles, as in typical H. stuppea?
Cheers,
Jacques

Re : Pyrenomycete with hyaline thickwalled hairs
Thank you Jacques,
I checked on tubercles, but there are none. I think it is indeed a species related to Helminthosphaeria stuppea. Maybe it's the same Europaean species which has been discussed many times here under the name Lasiosphaeria stuppea.
