Pseudocapsa sp. ( Figs. 8F–8G ).

Isolated or composed colonies formed by round to irregular sub-colonies, 6.4–12.5 µm diam. Sheath firm, hyaline to dark brown, conspicuous, non-lamellate, smooth. Cells hemispherical to irregular, 2.9–4.4 µm diam., radially arranged in mature colonies. Cell content homogeneous, pale blue-green.

Habitat: —Dry wood.

Notes: —This population resembles P. dubia differing mainly by habitat, which is a wet cave wall for P. dubia and dry wood for Pseudocapsa sp.

Studied material: — BRAZIL. São Paulo: São Luís do Paraitinga, State Park of “Serra do Mar” ( Santa Virgínia ), 23º 20’ 12” S, 45º 8’ 44” W, 23 February 2010, W.A. Gama-Jr. (SP 401421) .
