Riccia sarcosa Volk & Perold, a new species endemic to southern Africa is described. This species belongs to the section Pilifer Volk (1983), which now comprises 8 species characterized by the dorsal epithelium consisting of loose cell pillars. R. sarcosa is recognized by the distinct white margins of the thallus, by inconspicuous hyaline scales that do not extend above the thallus margins and by the spore ornamentation consisting of round, deep-set areolae or foveae.
