　Description： Hyphae vegetativae plerumque submersae, hyalinae. Sporophora erecta vel ascendentia, laevia, postea prostrata et distanter septata; stipites principales 900-4000 μm longi, 2.5-5 μm lati, dichotomis successivis usque ad septem praediti; rami basiles 600-2000 × 2.5-5 μm; rami paenultimi 8-25 × 1.3-1.5 μm; rami termiles 6-18 × 1 μm. Cellulae capituli deciduae, globosae, projecturis conicis, (2-)3-5(-6) μm diam, merosporangis 3-15 praeditae. Merosporangia bispora, spora apicali e spora basili inflata. Sporangiosporae ellipsoideae, laeves, hyalinae, (4-)5-6(-7) × 3-4(-4.8) μm, massis sporae siccis ad maturitatem persistentibus. Zygosporae super vel sub pagina agari factae, globosae, verrucosae, 33-37 μm diam, brunneolae, suspensoribus septatis 22.5-27.5 × 12.5-13.8 μm. Vegetative hyphae usually submerged, hyaline. Sporophores erect or ascending, smooth-walled, becoming prostrate and distantly septate in age; main stalks 900-4000 μm long, 2.5-5 μm wide, bearing up to seven successive dichotomies; basal branches 600-2000 × 2.5-5 μm; penultimate branches 8-25 × 1.3-1.5 μm; terminal branches 6-18 × 1 μm. Head cells deciduous, globose with conical projections, (2-)3-5(-6) μm diam, bearing 3-15 merosporangia. Merosporangia two-spored, with the apical spore budding from the basal spore. Sporangiospores ellipsoidal, smooth-walled, hyaline, (4-)5-6(-7) × 3-4(-4.8) μm, spore masses remaining dry at maturity. Zygospores formed on or under the surface of agar media, globose, roughened, 33-37 μm diam, light brown, with septate suspensors 22.5-27.5 × 12.5-13.8 μm.

　Note： This species is characterized by delicate sporophores, globose head cells, and two-spored sporangia. The apical spore buds from the basal one. Piptocephalis lepidula (Marchal) R. K. Benjamin appears closely related to this species but differs in having more robust, distinctly striated sporophores and narrower sporangiospores.
