I found this very small (about 150um) & nice fungus between Algae on bark of Sorbus about 1m above the ground. I think this is a member of Bionectraceae parasiting on Algae.
The fungus has spores with very high OCI and orange LBs in KOH negative cells of the wall. I have no idea, but maybe someone knows this fungus and/or can propose a genus ?
best wishes
Pimpek

AMY ROSSMANN:
Dear Piotr,
[...] It is definitely a member of the Bionectriaceae but, of course, determining the correct genus is difficult. As you know, Peter Dobbeler has seen many more of the hypocrealean fungi associated with mosses and lichens. I do not think your fungus is Ochronectria. Rather it may be a Hydropisphaera based on the cupulate collapse of the fruiting body. You should make a section or even in a squash mount to see if the cells in the perithecial wall have very thin walls? If so, it may be Hydropisphaera. Otherwise, it could be Pronectria as it appears to be slightly immersed or one of Peter's unusual fungi such as Bryonectria. I am no longer working on members of the Bionectriaceae so I will forward your email to Peter and Roz Lowen who has looked at a lot of lichenicolous fungi.
All the best!
Amy
P.S. You should attempt to grow this in culture in order to sequence it and really help determine relationships among these difficult fungi. At the very least, if you obtain a culture, but do not have sequencing facilities, you can deposit the culture at CBS where some day someone might sequence it. These kinds of fungi are rare in culture collections so conducting sequence work to determine relationiships is difficult.

PETER DOBBELER:
"Lieber Piotr
Ihr Pilz gehört sicherlich nicht zu den bryophilen Gattungen Bryonectria oder Bryocentria. Mehr kann ich nicht sagen. Man müßte einmal nachsehen, ob nicht irgendwelche lichenicole Hypocreales in Frage kommen. Es gibt ja nicht viele Gattungen und insgesamt auch nicht sehr viele Arten. Ich hoffe, Sie haben Erfolg. So ein schöner Pilz verdient einen Namen!
Beste Grüße Peter Döbbeler."
