Hello,

this beautifil species was collected several times at leaves of Rubus chamaemorus. Could be from Rutstroemiaceae, but i have not succeeded in finding necessary description there. Four related species which could be found at this host: Sclerotinia tetraspora, Ciboria latipes, Scleromitrula rubicola, Rutstroemia chamaemori - all have different spores (no mention of allantoid shapes).

May be somebody is familiar with this?

 Apothecia cupulate, stipitate, 1.3–4.7 mm in diameter, stem 0.8–2 mm high, site densely at both leaf sides, without sclerotia but black stromatized lines are present at the leaf; reddish-brown, hymenial surface minutely speckled, outer surface longitudinally rugose, stem base dark to dark brown.

Excipulum from porrecta, outer hyphae incrusted by brown pigment, at the edge not enlarged hyphoid elements; asci with crozies, euamyloid ring, 97.6–125 x 12.5–14; paraphyses cylindrical, enlarged to upper part, rarely branched, septated, with brown content in upper part, about 113 x 4.4 (width at upper part); spores allantoid, with two medium oils and several tiny, 17 (15.4–18.9) x 4.7 (4.1–5) (n=11).
