Position in ITS phylogenetic tree
Colonies and cardinal temperatures
Colony morphology submerged and faintly petaloid on V8A and CA, and stoloniferous, dense-felty colonies on PDA. Optimum growth temperature 20°C and maximum 27.5°C.
Conditions for growth and sporulation
Sporangia were nonpapillate, persistent, and predominantly ovoid to broad ovoid and obpyriform in shape. Sporangia averaged 59.2 x 37.1 µm (overall range 35.5–72.4 x 28.3–50.8 µm), proliferation internal, nested. Sporangiophores unbranched. Hyphal swellings present. Chlamydospores absent.
