Triblidium yunnanense

Ciri dan struktur

Different from T. hafellneri by its ascospores with 6–8 transverse septa, narrow asci and geographical range. Different from its phylogenetically closest relatives (T. hubeiense and T. rostriforme) by the size and the shape of ascomata and ascospores. Holotype. On twigs of Rhododendron sp., CHINA, Yunnan Province, Lijiang, Laojunshan, 26.6571 N; 99.6944 E, alt. ca. 4070 m, 25 June 2011, C.-L. HOU 875A (BJTC 201903). Ascomata erumpent from bark, circular or slightly irregular in outline, 0.5–0.8 mm diam., solitary, with a black (#211414) outer surface that is sculptured with polygonal areolae, opening by irregular splits to expose the hymenium. In median vertical section, ascomata 300–400 μm thick. Covering stroma 45–75 μm, consisting of an outer layer of highly melanized hyphae with remnants of host tissue incorporated into the outer surface and an inner layer of hyaline hyphae. Basal layer 45–88 μm thick, composed of an outer layer of highly melanized hyphae and short, thick, hyaline hyphae towards the internal matrix of stroma that is 60–85 μm thick, composed of thick hyphae. Subhymenium 35–59 μm thick, consisting of hyaline textura angularis. Excipulum 25–35 μm thick, formed by marginal paraphyses. Paraphyses 180–230 × 1–1.2 μm, filiform, often branched, multi-guttulate, guttulae visible in water and IKI but disappearing in both lactophenol solution and 5% KOH. Asci ripening sequentially, 150–200 × 13–18 μm, cylindrical, thin-walled, without circumapical thickening, rounded at the apex, 6–8-spored. Ascospores 20–30 × 10–15 μm, L/W ratio of 1.7–2.5 (average ratio of 1.99), ellipsoid, hyaline, at first aseptate, becoming muriform at maturity, with usually 6–8 transverse septa and a few longitudinal and oblique septa, without gelatinous sheath, inamyloid in IKI.
