| Description： |
On shrimp shell: Sporangium spherical, subspherical, 20.5-44 μm diam., or pyriform, with a hyaline wall which bears 3-20 simple, triangular, rarely bifurcate, tapering pegs. Apophysis subspherical, 7.5-10 μm diam., rhizoids arising from base or sides of apophysis. Zoospores spherical or ovoid, 4-5 μm diam., with a conspicuous refractive basal globule and several small globules, emerging through a subapical or lateral exit tube and swarmed in a vesicle then moving away. Resting spore spherical, 13-23.5 μm diam., thick wall, with numerous triangular spine, golden color. In 1/4YpSs slush: Sporangium spherical, 8.5-32.5 μm diam., or pyriform, 15-27.5 × 20-35 μm, wall bears 1-5 simple triangular spine. Apophysis spherical, 7.5-17.5 μm diam., rhizoidal system arising and extending. Zoospores spherical, 5-6.5 μm diam., emerging in a vesicle, group swimming then moving away. | |||

| Note： |
This genus includes two species, which occur as saprophytes in insect exuviae and on chitin bait (Sparrow, 1960). Thallus development belongs to Chytrium type. Several blunt spines on the surface of sporangium, and rhizoidal system arising from the bulbous apophysis are the main characters. | |||
