Sakireeta madreeya Subram. & K. Ramakr., J. Indian bot. Soc. 36: 84 (1957)

Tiarosporella madreeya (Subram. & K. Ramakr.) Nag Raj, Can. J. Bot. 51(12): 2470 (1974) [1973]

Facesoffungi number: FoF 07584

 

Saprobic on dead culms of Aristida setacea. Sexual morph: undetermined. Asexual morph: Conidiomata brown to dark brown, pycnidial, aggregated, immersed, globose to depressed globose, mostly irregularly multilocular in a stroma, glabrous, ostiolate, thick-walled. Conidiomata wall composed of thick-walled, brown cells of textura angularis in the outer layers, becoming hyaline cells towards conidial hymenium. Conidiophores reduced to conidiogenous cells. Conidiogenous cells 8–10 × 2.5–4 µm, hyaline, holoblastic, cylindrical to ampulliform, determinate, smooth-walled, and arising all around the cavity of the conidioma. Conidia 17.5–26 × 4.59.7 µm ( = 20 × 6.5 µm; n = 30), hyaline, subcylindrical to narrowly ellipsoidal or clavate, rounded at the apex, slightly truncated at the base, unicellular, initially bearing a cone-shaped, mucoid, apical sheath which splits into three or four, tentaculiform, undulate appendages.
