ABSTRACT. A new species from China, Podperaea baii, is described. In addition to morphological differences from the second species of the genus, P. krylovii (Amlyste­giaceae s.l.), P. baii differs in the nrITS1 sequence, which is very similar to that of the genus Herzogiella from the phylogenetically distant family Plagiotheciaceae. At the same time, nrITS2 in P. baii is much more similar to Amblystegiaceae than Plagiotheciaceae. This case is the first report of the putative remote hybridization in mosses.
