Assessment Notes

Taxonomic notes

Colonies white, becoming gray, with rapid growth at 28 °C in BDA.  Stolons and rhizoids present. Sporangiophores arising from stolons (never in whorls), some from substrate, hyaline to brownish gray, erect or bent, simple or branched up to 3 times, 25–170 μm in length. Sporangia blackish-gray, apophysate, wall deliquescent, globose or subglobose, 15–30 μm diam. Columellae hemisphaerical, spherical, ovoid to spatulate, 8–30 × 6–15 μm, smooth or with one several distorted projections, 1–2 μm in length. Sporangiospores spherical, hyaline to gray, smooth- to slightly rough-walled, 4–6.45 μm in diam. Giant cells abundant, “femur head”-like or finger-like, 36–165 μm. Zygosporangia not observed.
