Hyphomycete on Ascocoryne inflata

Hello, I have here a conidial fungus that I observed on the disc of living Ascocoryne inflata where it forms black patches. I was unable to find a genus or species name for it.
The conidia measured 15-22 x 7.5-10 µm.
Data: 14.XI.2021, Tübingen-Pfrondorf, Brand, rotten Betula pendula log, HB 10222b
Brachysporium is excluded by the broad attachment of the conidia. With Ellis & Ellis (miscell.) I arrive in the key at Endophragmia.

Hi Zotto
This is an Endophragmiella species (which were included in Endophragmia in Ellis & Ellis).
E. uniseptata has 1-septate conidia of roughly the same size & shape as your specimen - attached images are from a UK collection. But this isn't a definitive identification!
I'm not aware of E. uniseptata being fungicolous. It normally occurs on dead wood.

Indeed, this matches very well. I saw a few narrower conidia too, compared to the protologue, but they might be exceptional. Conidial shape and the basal scar fit perfectly.

Hello both
I've just spotted this thread. Sivanesan published a paper proposing a teleomorph for this fungus. The PDF appears to be too big to attach here - I'll email it you.
Best wishes, Chris
