Type Information
Type locality: Signy Island, South Orkney Islands, Antarctica; (Broady 1976: 398) Holotype: fig. 5 a-j: 1972; moss and soil; Cambridge Collection of Algae and Protozoa; Culture No.176/2 (Broady 1976: 398)
Description
Broadly ellipsoidal to subspherical unicells, up to 11 µm diam., distributed throughout softly
mucilaginous, multicellular, irregular, light green colonies in groups of two, four, eight and
sixteen cells. Large adult cells occasionally irregularly distributed. Occasional faint, concentric
stratifications present in the mucilage around cell groups. Adult cells with a thin, smooth cell
wall, becoming slightly uniformly thicker, up to 1-5 µm, in old cultures, containing a single
nucleus and a single green, parietal, broadly lobed chromatophore with a faint pyrenoid.
Autospores, four, eight and more rarely two or sixteen, released by irregular rupture of the
sporangium. Fragments of the sporangium wall may remain visible or become gelatinous.
Young spores narrowly ellipsoidal to almost cylindrical, 7-9 x 3-4 µm, with a variably lobed,
parietal chromatophore. Oil globules usually present in both adult cells and autospores.
