Conditions for growth and sporulation
Sporangia were papillate, caducous, and predominantly ovoid and limoniform in shape. Sporangia averaged 38.3 x 23.2 µm (overall range 19.3–62.6 x 9.2–36.7 µm), external proliferation. Sporangiophores dense sympodia. Hyphal swellings absent. Chlamydospores absent.
