Original description as Hystrichosphaeridium recurvatum subsp. polypes: [Cookson and Eisenack, 1962, p. 491]:

Diagnosis:
Shell circular to sub-circular in outline with fourth or more slender appendages of approximately uniform width throughout except for a slight broadening at the base; the tips of the appendages are fringed with short and straight or recurved processes, which divide once or twice into short, hair-like branches that are visibly only with the aid of an oil-immersion objective. The surface of the shell is finely granular.

Dimensions:
Over-all diameter ca. 52-99 µm; shell 33-57 µm; appendages ca. 15-25 µm.
