Hi! One more found on old Populus tremula log in O
I've received photos and descriptions of two ascomycetes that are troubling me a bit. The first one shows some similarities with Byssolophis but I think Byssolophis species should have larger ascospores... So maybe it's something else? Here's a short description:
On wood of a dry, decorticated branch of probably Castanea, 3 cm in diameter.
The ascomata are small, +- spherical and have a slit-like ostiole. They sit on a black subiculum. The asci are uniseriate, negativ in Lugol and measure about 45-55 x 4-5 µm. The ascospores are hyaline and have one transverse septum at which they are strongly constricted. They measure about 5-7(8) x 3 µm. The hamathecium consists of long, filiform elements.
Thanks for any help!
Best wishes,
Gernot

nachdem mein Internet vor zwei Tagen komplett den Geist aufgegeben hat, kann ich nun endlich antworten. Anteaglonium passt sehr gut, vielen Dank! Mit dem Schlüssel in Boehm et al. (2009) kommt man aufgrund des Subikulums/Tomentums zu A. globosum. Ein grünes Pigment ist in KOH auch zu sehen (siehe angehängtes Foto der Finderin).
Schöne Grüße

Typical A. globosum, exactly.
