No specimen available

Growing on bark.
At first sight it looks like some Melaspilea, but the microscopy is somewhat different from that and I was not able to recognize even the genus of it.
The spores (only few observed) are submuriform with dimensions in the following ranges: 26.8 – 29.5 × 6.9 – 7.5 µm.


Microscopy: Asci and spores (x1000, in CBLA); CBLA = cotton blue in lactic acid;
Microscopy: Apothecial sections (x400, in water);
Microscopy: Hymenium views (top – in water, bottom left – in IKI and bottom right – in lactophenol blue);
Microscopy: Asci (x1000, in CBLA);
