Analyses of miscellaneous materials of green-gemmous Lophozias have shown: (1) L. silvicola is a distinct species from L.ventricosa.(2) L. iremelensis is synonymous with L. ventricosa and treatment of the former as conspecific with L. wenzelii is erroneous.(3) Jungermannia groenlandica is a distinct variety of L. wenzelii.(4) The separating of the sect.Guttulatae is unfounded because of absence of constant defining features from sect.Lophozia.So, sect.Guttulatae should be rejected.(5) L. silvicoloides seems to be a more or less common species of East Siberia and Far East with a few disjunctions in Europe.The species is close on the one hand to L.silvicola and on the other hand to L. ascendens.Two new combinations are proposed: Lophozia ventricosa var.guttulata (Lindb.et H. W. Arnell) Bakalin comb.nov.and Lophozia wenzelii var.groenlandica (Nees) Bakalin comb.n.The key for identification of Holarctic's green-gemmous Lophozias is presented.
