Cyanoarbor aff. himalayensis M.Watanabe & Komárek


Cyanoarbor aff. himalayensis M.Watanabe & Komárek   in Branco et al. (2006: 373) ( Figs. 11D–11E View FIGURES 11 ).

Polarized, elongated and lobed colonies, 79.8–157.6 µm diam. Sheath firm, hyaline to brown, conspicuous, nonlamellate, smooth. Cells spherical to slightly elongated, 2.3–3.2 µm diam., arranged in rows. Cell content homogenous, blue-green.

Habitat: —Dry concrete wall.

Notes: —The genus Cyanoarbor Wang (1989: 129)   was rediscovered and revised by Branco et al. (2006), 17 years after its original description. In this paper, the authors also published the species Cyanoarbor himalayensis   , which resembles the Atlantic Rainforest population by the similar color of the colonies and cell dimensions. However, C. himalayensis   was described from mountains in Nepal, growing on wet rocks, and only rarely has cells organized in rows (Branco et al. 2006). Our population was found on a dry wall surrounded by a preserved Atlantic Rainforest area, with cells always organized in a linear fashion.
