Endospora rubra Gardner (1927: 28) ( Figs. 6H–6I View FIGURES 6 ).
Sarcinoid to irregular colonies, 13.0–51.2 µm diam., sub-colonies paired with each other. Sheath firm, hyaline to rusty red, conspicuous, lamellate to non-lamellate, finely granulated. Cells polygonal, (4.4)6.5–9.5(16.3) µm diam. Cell content granulated, blue-green.
Habitat: —Wet rocks and dry roof.
Notes: — Bourrelly (1970) considered Endospora rubra in the genus Myxosarcina Printz (1921: 35) . However, neither this author, nor Gardner (1927), described the typical baeocyte formation for this species, which is diacritical in Myxosarcina . Komárek & Anagnostidis (1998) suggested that E. rubra belonged to the genus Cyanosarcina Kováčik (1988: 175) , since this species had the typical sarcinoid colonial arrangement. However, Cyanosorcina is not described as having colored envelopes, which is typical for E. rubra . The genus Gloeocapsopsis Geitler ex Komárek (1993: 23) has all these features: 1) the sarcinoid arrangement of colonies; 2) the colored sheaths; and 3) the formation of resistant cells by thickening of cell envelopes when they are inside the colony. Based on morphological features and since baeocytes were never found in the Brazilian material, we suggest that E. rubra truly belongs to the genus Gloeocapsopsis . However, due to lack of information on the phylogenetic position of Gloeocapsopsis and its related genera like Cyanosarcina and Asterocapsa Chu (1952: 97) , we choose not to synonymize these taxa yet.
