Hyaloscyphaceae gen. sp.
Nina Filippova, 17-07-2013 17:03
This tiny Hyaloscyphaceous species collected from leaves of Rubus chamaemorus (one group of many apothecia) and once underdeveloped apothecia were met at leaves of Cranberry (probably not host specific saprotroph). No idea about its position yet ).

Apothecia cupulate, stipitate, tiny, 110–180 mkin diameter, 150–210 high; outer surface hairy and slightly powdery, receptacle white, stem brownish.

Excipulum in stem from brown segmented hyphae, at flanks from enlarged ellipsoid cells about 7 in diameter, with thickened walls; hairs arise from stem, outer surface and edge, conical (gradually narrowing to tip), hyaline (brown in stem), not strongly incrusted, 21–32 x 2.6–3.5; asci clavate, with crozier, with euamyloid small ring, 35.7–42 x 4.9–6.2; paraphyses cylindrical, slightly enlarged at tips, with pale elongated vacuoles, medium size 31 x 1.6; spores pip-shaped, hyaline, without oils, 5.2 x 1.5 (n=2).?

Re : Hyaloscyphaceae gen. sp.
I think it is Betulina fuscostipitata, now placed in Hyaloscypha. The genus Fuscoscypha was an option to transfer the species, but molecular results indicated that this genus should be merged with Hyaloscypha.

Hyaloscypha fuscostipitata (Graddon) Baral & Huhtinen, Karstenia 49(1): 15 (2009)

I know it from Castanea and Carpinus leaves, but he type was on Betula.
