Arecophila australis

Ciri dan struktur

Arecophila australis differs from similar species by its dimension of ascospores (22.5–29 × 8–11 µm) covered by striations and ascomata with a disc area surrounding the ostioles. Holotype. China, Guizhou Province, Guiyang City, Forest Park of Guiyang (26°32'55"N, 106°45'25"E), on dead culm of Phragmites australis (Cav.) Steud., 15 March 2014, Q.R. Li, GZ58 (GZUH0112, holotype, ex-type: GZUCC0112; GACP QR0152, isotype). Saprobic on dead culm of gramineous host. Sexual morph: Ascomata 420–560 × 290–380 µm (x̄ = 495 × 325 µm, n = 10), immersed under a clypeus, solitary, slightly raised, blackened, dome-shaped areas, scattered or gregarious, globose to subglobose, with a central, erumpent, cone-shaped papilla in vertical section. Clypeus black, comprising host cells and intracellular brown hyphae. Ostioles papillate, black. Peridium 15–25 µm (x̄ = 21 µm, n = 15) wide, comprising several layers, outer layer brown, thick-walled angular cells, inner layer hyaline. Paraphyses 3.3–5 μm (x̄ = 3.5 µm, n = 15) wide, hyaline, unbranched, septate. Asci 140–230 × 15.5–24 µm (x̄ = 183.5 × 19 µm, n = 30), 8-spored, unitunicate, long-cylindrical, short-pedicellate, apically rounded, with a 4–5 × 2.5–3 μm (x̄ = 4.5 × 2.7 μm, n = 20), trapezoidal, J+, apical ring. Ascospores 22.5–29 × 8–11 µm (x̄ = 25.5 × 9 µm, n = 30), overlapping uniseriate, 2-celled, light brown to brown, equilateral ellipsoidal, constricted at the septum, longitudinal with sulcate striations, along the entire spore length, surrounded by a mucilaginous sheath, lacking germ slits and appendages. Asexual morph: undetermined. Colonies on PDA, reached 3 cm diam. after one week at 25 °C, white, cottony, flat, low, dense, with slightly wavy margin.
