Gloeocapsopsis sp. 1


Gloeocapsopsis sp. 1   (Figs. 7C–7E).

Sarcinoid, round to irregular colonies, 14.6–159.4 µm diam., sub-colonies often present, overlapping. Sheath firm, hyaline to orange, rusty red, conspicuous, lamellate, finely granulated. Cells ellipsoid, hemispherical to polygonal, 6.1–10.6 µm diam. Cell content granulated, blue-green to olive-green.

Habitat: —Dry tree bark.

Notes: —The studied population is morphologically similar to G. dvorakii   and G. magma   (Brébisson in Brébisson & Godey 1835: 40) Komárek & Anagnostidis ex J. Komárek (1993: 24). Usually, these species do not have lamellate sheaths and the coloration pattern found in Gloeocapsopsis sp. 1   is different than the other species of Gloeocapsopsis   . These features were consistently observed in all three populations found in the Atlantic Rainforest. Except for G. ferruginea Komárek & Watanabe (1998: 123)   , which was found epiphytic on filamentous algae in a lake, all Gloeocapsopsis species   are described from rocks, a different habitat than the analyzed material.
