Saprobic on decaying submerged wood in freshwater habitats. Asexual morph: Colonies on natural substrates effuse, scattered, brown, glistening, with masses of conidia at the apex of conidiophores. Mycelium mostly immersed, composed of septate, smooth-walled, pale brown to hyaline hyphae. Conidiophores macronematous, mononematous, erect, slightly curved, solitary, cylindrical, smooth-walled, septate, unbranched, brown. Conidiogenous cells polyblastic, integrated, terminal, determinate, brown to pale brown, cylindrical or swollen, percurrently proliferating, with the apex becoming swollen and new conidiogenous cells formed enteroblastically then breaking through the outer wall, often remaining the lower flared fragments that not attached to the new conidiogenous cell. Conidia acrogenous, clustered in masses, globose, subglobose or obovoid, uniseptate, brown, guttulate, thick-walled, truncate or concave at the base with a minute marginal frill. Sexual morph: Undetermined.
Type species: Uvarisporella aquatica J. Yang, Jian K. Liu & K.D. Hyde.
