THAILAND, Nakhon Ratchasima Province, Khao Yai National Park, 22 Jul. 2009, K. Tasanathai, S. Mongkolsamrit, P. Srikitikulchai, R. Ridkaew, holotype BBH 30055, ex-type living culture BCC 45127.
Habitat:
Twig of a tree
Host:
On horsefly (Tabanidae, Tabanus sp.).
Description:
Stromata stipitate, usually two stromata arising from the thorax region of host, beneath the wings, capitate, unbranched. Stipes cylindrical, smooth, tough, brownish-orange, 4–10 mm long, 1.5–2 mm wide. Sexual morph: Fertile head hemispherical to globoid, upper surface slightly convex, moderate orange, located at the terminal part of stipes, 2–3 mm thick, 3–4 mm diam. Perithecia immersed, ovoid to obclavate, 1000–1180 × 320–450 μm. Asci cylindrical, 550–880 × 4–6 μm with cap 3–6 μm thick. Ascospores filiform, multi-septate, breaking into 64 part-spores, cylindrical to fusoid, 10–14 × 1–2 μm. Asexual morph: Synnemata usually arising from posterior abdomen region of host, solitary, cylindrical, unbranched, uneven and rough when aged, brown to dark brown at the base, moderate orange at the apex, 5–10 × 0.5–2 mm, fertile part located at the terminal ends of the synnemata. Conidiogenous cells hymenostilbe-like, phialidic, forming a hymenial layer. Phialides cylindrical with short crowded denticles, 12–20 × 3–4 μm. Conidia hyaline smooth-walled, fusoid, 5–10 × 3–4 μm.
Culture characteristics:
Colonies on PDA attaining a diam of 10 mm in 30 d, high mycelium density, white, reverse pale yellow. Conidia and reproductive structures not observed.
