I hope for some hints...
Macro: Perithecia globose, black, glabrous, slightly tapered toward the ostiole, slightly furrowed around the ostiole, 0.4-0.6 mm in diameter. Perithecia always seated in a black mat (see below).
Micro: Spores abruptly and strongly bent in the lower part, with a minute, rounded, hyaline appendage at the lower end, ca 1 µm long. Spores observed in Perithecia were always aseptate and hyaline, but (mostly overmature) Spores from Perithecial surroundings had 3 septa and were very slightly brownish. Spore size mostly 18-22 x (5)-6-8 µm (at the broadest part). Asci have a minute, inamyloid, refractive ring.
Black mat: This is a conidial stage with dark brown, fusiform conidia with a long, straight germ slight (as in Xylariaceae). I wonder if this actually belongs together with the Perithecial fungus?
Many thanks and best wishes,
Stefan
