Ewamiania G.B. McGregor & B.C. Sendall (2017: 43)
Type: E. thermalis G.B. McGregor & B.C. Sendall (2017: 46)
Filaments densely arranged to form blackish-green hemispherical caespitose mats. Filaments isopolar, cylindrical, straight or flexuous, densely arranged and erect, often parallely fasciculate, with tolypotrichoid false-branching, rarely with scytonematoid false-branching. Vegetative cells short barrel-shaped or isodiametric, 0.5–1.2 × as long as wide, slightly constricted at the cross walls, with granulated contents; terminal cells widely rounded. Sheath firm, relatively thick, lamellated, uncoloured to yellowish or yellow–brown in colour, cylindrical, closed at the apex. Heterocytes basal and intercalary, solitary, rarely up to 2(3) in series, developing particularly at the base of branches, spherical or ovoid. Akinetes not known. Reproduction by hormogonia, often with terminal heterocytes, not constricted at cross-walls, separated by necridic cells. A monospecific genus, with one species known from a thermal spring complex in tropical north-eastern Australia.
