Dear forum,

i am currenly working with collection of Perithecia-forming species inhabiting Andromeda leaf litter. My orientation in the systematic space of this group is still poor. Could you possibly give me a clue on approximate position of this representative?, it seems beautiful and distinctive one.

On fallen leaves of A. polifolia, C. calyculata, L. palustre in raised bog community.

Ascomata scattered on both sides of the leaf, sphaerical, superficial, setose around the pore, and with descending hyphae in lower part, up to 150 mk in diameter.

Setae brown, septate, thick-walled, straight and short near the pore, bent and longer outward, 40-80 mk long, 8 mk broad at base, narrowing to obtuse tip; descending hyphae brown, septate, about 1 mk broad; asci clavate, attached to stalks which connected together in bunches, 20–23 x 8–9.6 mk, dehiscence mode unclear; hamathecium from elongated thin elements surrounded by gelatinous substance; spores hyaline, two-celled, with deep constriction, with many small to medium oil guttules, measured in vital state 10 (9–1.8) x 3.5 (3.3–3.9) mk (n=22).
