Plants up to 7 cm tall; discs at first funnel-shaped, later nearly flat, often 2-4 of successive ages superimposed, becoming 12-20 mm diameter; rays 30-80, closely united by moderate lime encrustations. The apices at first rounded, later truncate, the distal wall sometimes incrassate with an evident median apiculus, at least while young; lobes constituting the corona superior crowded, elongate, rounded or slightly indented peripherally, carrying 2 hair scars in a radial line. Lobes of the corona inferior also crowded, elongate, very deeply indented peripherally. Aplanospores to 500 in each sporangial ray 65-80 ยต diameter. Gametangia up to 48. Thallus solitary or in clusters, parasol shaped, moderately calcified; discs one or more, flat or cup shaped, stalk slender; holdfast small, pad-like.
