D2CA6CB8185D00C4384C7D0F2A509542.taxon	diagnosis	Diagnosis. Characterised by the presence of both lanceolate and cylindrical paraphyses, fusoid-clavate ascospores with a length / width ratio of predominantly> 4 and free-ending hyphae at the inner excipulum of the tube-shaped, even collar. Saprophytic on dead branches of E. sylvaticum.	en	Haelewaters, Danny, Filippova, Nina V., Baral, Hans-Otto (2018): A new species of Stamnaria (Leotiomycetes, Helotiales) from Western Siberia.

D2CA6CB8185D00C4384C7D0F2A509542.taxon	description	Description. Apothecia urn-shaped, stipitate, 0.25 - 0.6 mm in diameter when mature, 0.5 - 1 mm high, varying depending on light conditions, being stouter with shorter stipe when substrate exposed to sunlight; receptacle light yellow (- ochraceous) when fresh, with even, whitish collar ~ 80 - 120 µm high, stipe pale yellowish-translucent, 100 - 380 x 130 - 300 µm, receptacle becoming light brown on drying; scattered to moderately gregarious, often abundant on the branches. Ectal excipulum outer layer * 40 - 45 µm thick at middle flanks and margin, made up of strongly gelatinous tissue of loose, parallel to wavy hyphae 2 - 3 μm broad, septate, embedded in abundant gelatinous matrix (textura oblita); inner layer * ~ 45 µm thick at middle flanks, made up of textura prismatica-porrecta running parallel to outside, cells at middle flanks * 17 - 44 x 7 - 12 μm, slightly narrower in the collar region, much narrower in stipe (* 20 - 45 x 3 - 5 µm); the inner layer of the collar composed of narrow hyphae, free upper part of these hyphae internally covered by lateral cellular outgrowths * 2 - 5 x 1.5 - 2 µm. Medullary excipulum well developed, of dense, parallel, septate hyphae (textura porrecta) without gel, cells * 65 - 90 x 2.5 - 6 (- 7.7) μm; subhymenium well developed (* 20 - 30 thick), of intricate hyphae * 2 μm broad. Asci cylindrical, developing from croziers which are difficult to see in mature asci, with apical thickening enclosing a hemiamyloid ring of Calycina-type (rb: dirty red at high, blue at low concentration), * 146 x 12.5 [123 - 159 (- 206) x 11.7 - 13.5] μm, † 98 x 9 (90 - 110 x 8 - 10.5) μm, 8 - spored, spores * obliquely biseriate. Paraphyses of two types: (1) lanceolate, exceeding asci for * 12 - 20 µm when young and * 30 - 40 μm when fully developed, septate in lower part, non-septate in broad upper part, with quite acute tip, in young paraphyses with granular (multiguttulate) vacuolar content of moderate refractivity (VBs), later replaced by larger non-refractive vacuoles, * 5 - 7 († 3 - 6) μm broad in upper part; (2) cylindrical, more abundant, not exceeding the asci, * 2.3 - 3 μm broad above, septate, with obtuse tip, rarely branched below and scarcely enlarged in upper segment, without VBs, with pale yellow-orange pigment in middle and lower part. Ascospores fusoid-clavate, slightly to distinctly heteropolar, with rounded to obtuse ends, usually without any gel around, filled with granular oil content in both halves, leaving a central zone for the single nucleus, variable in length, * 19.8 x 4.8 (16.5 - 24.5 x 4.2 - 5.6), n = 18, Q = 4.1 (YSU-F- 04933); † 20.5 x 4.0 (17.2 - 24.2 x 3.6 - 4.6) μm, n = 37, Q = 5.1 (YSU-F- 03519, YSU-F- 04933).	en	Haelewaters, Danny, Filippova, Nina V., Baral, Hans-Otto (2018): A new species of Stamnaria (Leotiomycetes, Helotiales) from Western Siberia.
