Type: Isotheciastrum subdiversiforme (Broth.) Ignatova, Fedosov & Ignatov
Basionym: Isothecium subdiversiforme Broth., Hedwigia View in CoL , 38: 237. 1899. Holotype: Nippon Nord , montagne d’Hakkoda, 5 juillet 1893, Faurie 826 (in H-BR!).
Etymology. The name means related to Isothecium , widespread genus of the Lembophyllaceae .
Diagnosis. Differs from Dolichomitra , Dolichomitriopsis and Isothecium in combination of (1) erect-spreading vs. mostly imbricate leaves; (2) leaf margins strongly dentate vs. serrulate, crenulate to subentire or, if dentate, leaf apices rounded; (3) capsules inclined, clearly asymmetric vs. erect or slightly inclined, symmetric or slightly asymmetric; calyptra occasionally with few hairs at base; endostome cilia 1–2, short vs. lacking, rudimentary or, rarely, well-developed. Broadly rounded to truncate proximal branch leaves ( Fig. 3M–O View Fig ) also differentiate it from other species of Isothecium -clade.
Species included: monospecific genus.
