Trichocoleaceae Mai et Johansen View in CoL fam. nov.
Description:— A monophyletic assemblage of genera based on 16S rRNA gene sequence phylogeny, with filaments containing one to many trichomes, obligately forming sheaths except in hormogonial stages. Sheaths thin and firm to soft and wide, lacking pigmentation. Trichomes slightly to distinctly constricted at the crosswalls, straight or flexuous, less than 5 μm wide. Cells shorter than wide, isodiametric, or longer than wide, with peripheral thylakoids, obligately without aerotopes, facultatively forming polyphosphate granules in the centroplasm. End cells cylindrical, rounded, rounded conical, conical, or attenuated to a point.
Type genus:— Trichocoleus (West & West) Anagnostidis
