general taxon notes:

 

When Mönkemeyer (1927) established the Cratoneuronaceae, he emphasized the morphology of polymorphous paraphyllia, the papillosity of median leaf cells, and the differentiation of alar cells. Ochyra (1989) considered that Cratoneuron includes one species and one variety, and the genus should be treated in the Cratoneuronaceae. Cratoneuron is here still placed in the Amblystegiaceae in a traditional way.

Stem leaves distantly foliate, erect or slightly curved, broadly ovate or ovate-lanceolate, usually abruptly acuminate toward apex; margins mostly serrulate; costae single, thick, ending below the apex or shortly excurrent; median leaf cells elongate-rhomboidal, 2–4 times as long as wide, thin-walled; alar cells distinctly differentiated, strongly convex, extending close to costa at leaf base. Dioicous. Setae 30–40 mm long, reddish brown; capsules elongate-ellipsoidal to cylindrical, reddish brown; opercula conic at base, apiculate to shortly rostrate at apex; annuli differentiated, usually 2–3 rows of small cells; exostome teeth narrowly lanceolate; endostome segments perforate, crack-like; basal membrane high; cilia 2–3, short, densely papillose, nodulose.
