Camptylonemopsis Desikachary (1948: 49)

Type: C. lahorensis (S.L.Ghose) Desikachary (1948: 49)

Filaments heteropolar, solitary or in small groups, bent, attached to the substrate by their basal parts, filament ends grow upwards forming U-shaped arrangements. Trichomes uniseriate, with cells generally widened towards the apices. Vegetative cells barrel-shaped, usually longer and narrower in the central parts of the trichome, shorted and wider at the ends; apical cells widely rounded. Heterocytes intercalary, generally towards the central regions of the trichome, spherical or barrel-shaped. Akinetes barrel-shaped to long-oval or cylindrical, arising in the central regions of the trichome.

Most of the 13 currently recognised species are known from tropical environments; here one species is described from north-eastern Australia. Bibliography: Desikachary (1948), Komárek (2003), Komárek (2013), Komárek et al. (2014).
