Gloeocapsopsis sp. 2 (Figs. 7F–7H).

Sarcinoid, round, elongated to irregular colonies, 71.7–123.2 µm diam., sub-colonies present, overlapping. Sheath firm, hyaline (rare) to dark-brown, conspicuous, non-lamellate, smooth. Cells irregularly spherical, ellipsoid, hemispherical, 6.7–10.6 µm diam. Cell content hardly granulated, olive-green.

Habitat: —Wet rocks.

Notes: —The population found was distinguishable from other Gloeocapsopsis species by the colonial arrangement, cell shape, and sheath color. Moreover, the cells were not polygonal and their content was intensely granulated, which is not seen in the other Gloeocapsopsis .

Studied material: — BRAZIL. São Paulo: Cananéia, State Park of “Ilha do Cardoso” ( Perequê ), 25º 4’ 12” S, 47º 55’ 27” W, 26 June 2010, W.A. Gama-Jr. & C.F.S. Malone (SP 427336) .
