Gongronella butleri (Lendner) Peyronel & Dal Vesco, Allionia 2: 370. 1955.

 Description: Colony growing slowly on SMA, about 3-5mm high with white turf. Sporangiophores 2.1-3.1 μm wide, hyaline, smooth to very faintly roughened, always with a septum under the apophysis beneath the sporangium, branching simply or irregularily. Rhizoids present. Sporangia globose, 16.6 -22.7 in diam, with thin, smooth and easily dissolved wall. Apophyses oval, 7.0-10.3 μm in length and 8.0-8.7 μm in diam with smooth surfaces. Columella reduced, hemispherical to dome-shaped, smooth, 2.1-4.2 μm in height, with collar around the base. Sporangiospores oval to flattened on one side to reniform, smooth, 2.5-7.2 × 1.7-4.7 μm in size. Chlamydospores observed in substrate mycelium, globose to ovoid with smooth surfaces, 4.9-6.8 × 4.6-10.7 μm in size. Homothallic. Zygosporangium globose, 16-36 μm in diam, roughened with warts about 2μm in height, with two nearly eaual suspensors.

 Note: The author identified this isolate as a member of Gongronella based on the following distinguished characters: rhizoids present; swollen, globose apophyses growing beneath sporangia and having reduced columella. Furthermore, this isolate has oval sporangiospores and erect sporangiophores, which can distinguish this species from the closet species Gongronella lacrispora Hesseltine & Ellis.
