Brycekendrickia indica
Brycekendrickia indica Nag Raj, Can. J. Bot. 51(7): 1337 (1973)
Saprobic on fallen and decaying leaves of Bambusa sp. (Poaceae). Sexual morph: undetermined. Asexual morph: Conidiomata 250–300 µm diam., 350–450 µm high, pale brown to brown, stromatic, pycnidial, mostly epiphyllous, solitary to gregarious or often confluent, initially immersed, then becoming partly erumpent, globose to subglobose, unilocular or multilocular, glabrous, ostiolate. Ostiole 100–200 × 100–200 µm, single, funneled to flabellate, centrally located. Conidiomatal wall 10–40 µm thick, composed of pale brown to brown, thick-walled cells of textura angularis in the outer layers, and hyaline, thin-walled cells of textura prismatica in the inner layers. Conidiophores arising all around the cavity of the conidiomata, hyaline, branched, septate, invested in a thin, non-persistent mucus. Conidiogenous cells 6–10 × 1–3 µm, hyaline, enteroblastic, phialidic, subcylindrical to obclavate, discrete or integrated, smooth. Conidia 10–14 × 1.5–3 µm (x= 12 × 2 µm; n = 30), hyaline, navicular with an obtuse apex and a narrow truncate base, aseptate, slightly curved, eguttulate, smooth-walled, bearing hyaline, branched, filiform, flexuous appendage at both ends (6 × 16 µm long).
