Gloeocapsa sp. 2 (Fig. 10C).

Elliptical to irregular colonies, 7.8–73.2 µm diam., 2–4 celled, rarely more. Sheath firm to diffluent, hyaline to brown and purple, conspicuous, lamellate or not, smooth to slightly granulated. Cells spherical to hemispherical, elongated after division, (2.6)3.1–3.8 µm diam. Cell content homogenous or with disperse little granules, blue-green. Spores not observed.

Habitat: —Tree bark.

Notes: — Gloeocapsa sp. 2 most resembles Gloeocapsa lignicola Rabenhorst (1865: 41) and Gloeocapsa compacta Kützing (1847: 24) , differing by the bluish color of colonies in the former, and the smaller cell diameter in the latter.

Studied material: — BRAZIL. São Paulo: São Luís do Paraitinga, State Park of “Serra do Mar” ( Santa Virgínia ), 23º 20’ 35” S, 45º 8’ 17” W, 24 February 2010, W.A. Gama-Jr. (SP 401426) .
