Chlorogloea sp. 2 (Figs. 10H–10I).

Polarized, round to elongated colonies, 19.1–154.4 µm length. Sheath firm to diffluent, hyaline, conspicuous, nonlamellate, smooth. Cells spherical to elliptical, 1.0–1.9(2.8) µm diam., arranged in rows, without individual envelopes. Cell content homogenous, pale purple.

Habitat: —Tree bark.

Notes: —The color of the cell content is one of the diagnostic features of Chlorogloea sp. 2 , in which it resembles Chlorogloea purpurea Geitler (1928b: 98) . However, this species is described as benthic on rocks in alpine lakes, a distinct habitat from the Atlantic Rainforest population.

Studied material: — BRAZIL. São Paulo: Cananéia, State Park of “Ilha do Cardoso” ( Perequê ), 25º 5’ 8” S, 47º 55’ 30” W, 30 June 2010, W.A. Gama-Jr. & C.F.S. Malone (SP 401443) .
