previous post of Exarmidium diaphanum gave me a hint about the position of one my unidentified specimen,

it was collected on dead branch of Chamaedaphne calyculata (N61,063892° E69,455695°). There is, probably, candidate, E. ericae, which described from twigs of Erica carnea (the same family) - i am comparing it now.

Hymenium developing under the clypeus, flat, with tiny pore (30 mk), to 400 mk broad, 80 mk thick, clypeus bluish-brown.

Clypeus from host epidermis cells and mass of greenish-blue chains of cells (some symbiont), no fungal tissue presented in clypeus (? may be it is not right to say clypeus then); asci fissitunicate, not amyloid, enlarged at base and with obtuse tip, thick-walled apex, 76 (70-85) x 16 (14-17); paraphyses cylindrical, 1,3-1,5 mk thick, with some guttules, branched; spores fusoid, 3-4-celled, cells of released spores enlarged to round (and then overall shape with constrictions), with two short cylindrical outgrowths from both ends, content with several big and many small guttules, 23,7 (20,8-26,6) x 7,9 (6,4-9,2) (18 spores).
