Hi.Found on wet deadwood (Salix?), fruitbodies in a group and very small (<1mm), black, roundish and only with the lower part in the wood, mainly on top. No necks or similar seen. Asci 8spored, Spores with some big drops and numerous small drops, spore length 25-30 µ, IKI-. When dry you clearly see 5 septae in the spore.
Any IDea?
Thx & regards Chris

Re : Pyreno on deadwood
A species of Chaetosphaeria, which one, I do not know.

Re : Pyreno on deadwood
Hi Chris,
Quite a few species of Chaetosphaeria are well described, but often the accompanying anamorph is needed for reliable species identification. But may be you are lucky because the spores are fairly large and 5-septate. Publications by Réblová 2000 and 2004 include keys (see for full references https://www.verspreidingsatlas.nl/0777030#, tabs "Artikelen" and "Standaardwerken").

Re : Chaetosphaeria
Thanks Andy and Eduard.
Chaetosphaeria should be right. Unfortunately I didn't see the anamorph (perhaps I didn't expect anything like this and therefore overlooked it?). From the Ascus and Ascospores' length and septations, and from the general description the closest I get is Chaetosphaeria cupulifera. At least I don't see anything that would contradict it, except that Ellis&Ellis don't show oildrops in their spore drawing (but in my last pic there are also no oildrops to be seen).
Thanks & best wishes
