I found this one today on a branch of Styphnolobium/Sophora japonica. The most striking features are the ascospores with longitudinal and vertical (sometimes also oblique) septa, a striate surface and the unitunicate asci.
The acomata are immersed, black and smooth, the ascospores are dark grey, 20-23 x 9-10 µm, with a striate surface, without a sheath (also in Indian ink), the asci are 8-spored, uniseriate, unitunicate, shortly stipitate and with a well visible apical apparatus which is CR+ and IKI-, paraphyses are present.
I didn't find anything similar in my literature and I'd be thankful for any help!
Best wishes,
Gernot
