The type specimen was collected from the Bambou Mountains (Grand Port District) at an elevation of 250–300 m (820–980 ft), where it was found growing on tree bark.

The species epithet bicolor refers to the notable visual contrast between the vivid blue-green cyanobacterial filaments and the white hyphal patches that give rise to the hymenophore.

These fibrils are horizontal to irregularly subascending, and have a vivid and uniform aeruginous color, often interspersed with white patches of densely woven, byssoid hyphae that eventually develop into hymenophores.

The hyphal sheath is formed by loosely arranged, cylindrical, and curved hyphae that wrap around the cyanobacterial filaments.

[2] The hyphae of the hypothallus and those associated with the fibrils or forming apical setae are straight, hyaline, 3–5 μm thick, and lack clamp connections.
