Tatraea yuxiensis

Ciri dan struktur

Saprobic on the decayed wood. Sexual morph: Apothecia 2.3–4.2 mm wide (x̄ = 3.0 ± 0.6 mm, n = 15) when fresh, 1.2–2.0(–2.5) mm wide × 0.47–0.72 mm high (x̄ = 1.6 ± 0.3 × 0.58 ± 0.09 mm, n = 18) when dry, scattered or gregarious, disk-like with short stipitate, glabrous, developing on the surface of the substrate. Disc flat and circular, slightly convex at the center and downward at the edge when fresh, edge slightly curls inward towards the center, edge of large ascoma somewhat undulating, orange grey (5B2) to brownish grey (5C2) when fresh, dark brownish black or deep green (1D8) to olive (1E8) when dry. Margins concolorous to the disc when fresh, white to pale yellow or concolorous to the receptacles when dry. Receptacle dark brownish black or dark ochraceous-brown when dry, slightly rough and finely pustules when mature. Stipe 270–480(–650) μm wide × 190–400 μm long (x̄ = 400 ± 86 × 320 ± 76 μm, n = 18), short, regular cylindrical, concolorous to the receptacle or nearly black, almost smooth on the surface. Hymenium 173–227 μm (x̄ = 210 ± 17 μm, n = 15), hyaline. Subhymenium not obvious. Medullary excipulum 273–330 μm (x̄ = 307 ± 22 μm, n = 15) thick, well-developed, comprised of thin-walled, septate, pale brown and slightly loose hyphae of textura intricata, hyphae (3.5–)4.2–8.7 μm (x̄ = 6.2 ± 1.5 μm, n = 70) diam., hyaline, becoming dense near to the hymenium, darkening, dense and well-organized parallel near to the ectal excipulum, non-gelatinous. Ectal excipulum of the inner layers generally comprised of 3–6 layers vertically oriented textura angularis cells, 34–62(–77) μm (x̄ = 49 ± 10 μm, n = 60) thick, pale brown to hyaline toward inwards, cells of inner layers 10.5–18.5(–20.4) μm (x̄ = 14.0 ± 2.6 μm, n = 100) diam., wall (0.49–)0.65–1.09(–1.3) μm (x̄ = 0.87 ± 0.15 μm, n = 100) thick; proliferate 3–4 layers irregular-shaped and minimal textura angularis or textura prismatica cells, 4.0–8.4 μm (x̄ = 6.3 ± 1.3 μm, n = 100) diam., wall 0.59–0.94 μm (x̄ = 0.77 ± 0.12 μm, n = 70) thick; terminal cells at margin obviously elongated to 17–33 μm × 3.6–5.9 μm, slightly curved and soft, apex rounded and sometimes swollen, thin-walled, pale brown or hyaline.
