Brycekendrickia indica

Brycekendrickia indica Nag Raj, Can. J. Bot. 51(7): 1337 (1973)

Facesoffungi number: FoF 07137

 

Saprobic on fallen and decaying leaves of Bambusa sp. (Poaceae). Sexual morph: undetermined. Asexual morph: Conidiomata 250300 µm diam., 350450 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 100200 × 100200 µm, single, funneled to flabellate, centrally located. Conidiomatal wall 1040 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 610 × 13 µm, hyaline, enteroblastic, phialidic, subcylindrical to obclavate, discrete or integrated, smooth. Conidia 10–14 × 1.53 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).
