Diagnosis:
Type species: Brachytrichiopsis filiformis Jao 1944. - Monospecific genus
Descriptions:
Komárek (1992): Filamentous - thallic; thallus irregularly cylindrical, mucilaginous up to filiform, attached by its basis to the substrate, narrowed to the apical end, divided in long, flexuous filamentous processi, up to 2 cm long and about 1 mm wide when old; later form gelatinous, layered mass; within mucilage numerous, irregularly tangled and freely coiled trichomes. Trichomes uni-serial, more or less cylindrical along the whole length, not attenuated towards the ends, clearly constricted at cross walls, torulous; trichomes irregularly true branched, branches morphologically identical with main trichomes; types of true branching: T-type, rarely V-type. Cells barrel-shaped, isodiametric or slightly longer or shorter than wide. Heterocytes present, solitary, intercalar, barrel-shaped. Akinetes unknown.
Genotype differences, molecular data:
Reproduction strategies, life cycles, cell division:
Komárek (1992): Cell division cross-wise, perpendicularly to the trichome axis. Reproduction by hormogonia or hormocytes.
