Hello. This species was overmature, lacking any spore-producing structures inside. But spores (or conidia?) were abundant, and their shape and perithecia form quite characteristic. So i hope its position could be defined from these features.

Coordinates: N60,891352° E68,690042°, 16.06.2014.

Perithecia on lower side of the leaf, scattered, submerged under epidermis with protruding neck, up to 400 mk high, perithecium about 150 mk in diameter, neck about 30-40 mk broad, with collar up to 100 mk.

Outer peridium from brown angular cells, covered with outgrowing hyphoid brown setae up to 200 mk long, 7 mk broad at base; neck covered by parralel brown hyphae 3-4 mk broad, in upper part of the neck these hyphae create rosette; spores cubical, about 6.7 x 6.3 mk, with thin wall on two opposite sides.
