Stamnaria yugrana

Ciri dan struktur

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. 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 × 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 × 7–12 μm, slightly narrower in the collar region, much narrower in stipe (*20–45 × 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 × 1.5–2 µm. Medullary excipulum well developed, of dense, parallel, septate hyphae (textura porrecta) without gel, cells *65–90 × 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 × 12.5 [123–159 (–206) × 11.7–13.5] μm, †98 × 9 (90–110 × 8–10.5) μm, 8-spored, spores *obliquely biseriate.
