Cytospora leucostoma

Ciri dan struktur

Necrotrophic on branches of Betulaceae, Juglandaceae and Rosaceae. Sexual morph: Ascostromata immersed in the bark, erumpent through the surface of bark, scattered, 950–2550 µm in diam., with 8–10 perithecia arranged circularly to irregularly. Conceptacle absent. Ectostromatic disc pale grey, fusoid, 600–2150 µm in diam., with 8–10 ostioles arranged irregularly per disc. Ostioles numerous, dark grey to black, at the same or above the level as the disc, concentrated, arranged irregularly in a disc, 60–120 µm in diam. Perithecia beige with a little black when mature, flask-shaped to spherical, arranged circularly to irregularly, 270–560 µm in diam. Paraphyses large, broad and cylindrical with 1–4 septa, 39–78 × 5.8–8.7 (av. = 50.6 ± 13.7 × 7 ± 0.8, n = 10) μm. Asci free, clavate to elongate obovoid, 35–45 × 6–8 (av. = 40.4 ± 3.3 × 6.9 ± 0.5, n = 10) μm, 8-spored. Ascospores uniseriate to biseriate, elongate-allantoid, thin-walled, hyaline, aseptate, 7–10 × 2–3 (av. = 8.3 ± 0.9× 2.6 ± 0.2, n = 30) μm. Asexual morph: Conidiomata pycnidial, immersed in the bark, scattered, erumpent through the surface of bark, with multiple locules and a conspicuous central column. Central column beneath the disc more or less conical, brown. Conceptacle absent. Ectostromatic disc buff, discoid, circular to ovoid, 190–310 µm in diam., with 1–2 ostioles per disc. Ostioles grey to black, at the same or above the level as the disc surface, 60–65 μm in diam. Locules numerous, subdivided frequently by invaginations with common walls, circular to ovoid, 700–1000 µm in diam. Conidiophores hyaline, branched at the base or unbranched, approximately cylindrical, 8–14 × 1–2 (av. = 11.5 ± 1.8 × 1.4 ± 0.2, n = 10) µm, sometimes reduced to conidiogenous cells.
