Chlorogloea sp. 3 ( Figs. 11A–11C ).

Polarized, round to elongated colonies, 16.4–133.2 µm length. Sheath firm, hyaline to reddish, conspicuous, lamellate, and finely granulated. Cells spherical to elliptical, 3.0–4.6 µm diam., arranged in rows, with individual envelopes. Cell content homogenous to slightly granulated, blue-green.

Habitat: —Dry rope and roof.

Notes: — Chlorogloea sp. 3 is morphometricaly similar to Aphanocasa richteriana var. major Gardner (1927: 4) , differing by the honey color of sheaths and presence of envelopes only in peripheral cells. In spite of Aphanocapsa being different to Chlorogloea , this variety has cells surrounded by individual and colored sheath, not typical in Aphanocapsa . Besides, Komárek & Komárková-Legnerová (2007) comment on the relationship of A. richteriana var. major with Chlorogloea species.

Studied material: — BRAZIL. São Paulo: São Luís do Paraitinga, State Park of “Serra do Mar” ( Santa Virgínia ), 23º 20’ 10” S, 45º 8’ 44” W, W.A. Gama-Jr. (SP 401433); 23º 20’ 10” S, 45º 8’ 44” W, 24 February 2010, W.A. Gama-Jr. (SP 401434) .
