Aquasubmersa mircensis K.D. Hyde & Huang Zhang, Cryptog. Mycol. 33(3): 340 (2012)
Saprobic on submerged wood in a freshwater stream. Sexual morph: undetermined. Asexual morph: Conidiomata 150–250 μm diam., 100–200 μm high, dark brown to black, pycnidial, subperidermal, solitary, semi-immersed, subglobose to ellipsoidal, thick-walled, unilocular, glabrous, ostiolate. Conidiomatal wall up to 20 μm thick, consisting of textura angularis with cells brown to hyaline, thick-walled. Conidiophores arising from inner layer cells of conidiomata, absent or occasionally present, subcylindrical to doliiform, unbranched, septate. Conidiogenous cells 10–15 × 4–7 μm, hyaline, holoblastic, subcylindrical to lageniform, determinate, discrete or integrated, thick-walled, smooth. Conidia 16–21 × 8–11 μm ( ̄x= 18 × 9 μm; n = 20), hyaline, ellipsoidal, rounded at both ends, or sometimes with papillate base, smooth, thick-walled, guttulate.
