Melomastia sinensis

Ciri dan struktur

Saprobic on a dead branch of Aquilaria sp. Sexual morph: Ascomata (excluding neck) 400–600 µm high × 430–580 µm diam. (x– = 515 × 520 µm, n = 10), solitary, scattered to gregarious, semi-immersed to immersed, erumpent through host tissue, globose to subglobose, black, coriaceous to carbonaceous, ostiolate. Ostiolar canal 230–365 µm high × 200–260 µm wide (x– = 303 × 230 µm, n = 10), central, black, conical, coriaceous to carbonaceous, filled with hyaline sparse periphyses. Peridium 30–120 µm wide (x– = 75 µm, n = 20), comprising dense, several layers of thick-walled cells of textura angularis to textura prismatica, outer layers brown to dark brown, becoming lighter inwardly. Hamathecium comprising 2.5–6.5 µm wide, numerous filamentous, filiform, septate, unbranched, hyaline pseudoparaphyses, attached to the base and between the asci, embedded in a gelatinous matrix. Asci 175–220 × 8.5–11.5 µm (x– = 195 × 10.5 µm, n = 30), bitunicate, 8-spored, cylindrical, long pedicel, thickened and rounded apex, with an obvious ocular chamber. Ascospores (17.5–)20–26.5 × 7–9 µm (x– = 24 × 8 µm, n = 30), overlapping-uniseriate, hyaline, when ascospores gather together, they appear light yellow, mostly 6–7-septate at maturity, cylindrical, with rounded ends, slightly constricted at the septum, often similar width of cells with several small guttules, not surrounded by a mucilaginous sheath. Asexual morph: Undetermined. Ascospores germinated on PDA after 24 hours, germ tubes were produced from most cells, germinated ascospores appear light yellow. Colonies on PDA reaching 3 cm diam., after two weeks at 23–28 °C.
