Results from our analysis of chloroplast trnL-trnF and nuclear ITS1 and ITS2 sequence data and 35 morphological characters for 134 taxa, of pleurocarpous mosses provide an evidence for resurrecting two moss families, Pseudoleskeaceae and Pylaisiaceae. Both these families were described by Schimper in 1860, but soon afterwards included in Leskeaceae and Hypnaceae, respectively, and apparently never used in the 20(th) century. However, sequence-level data analysis (chloroplast encoded trnL intron and trnL-trnF spacer, nuclear encoded ITS1 & ITS2), and combined molecular and morphological analysis demonstrate the remote position of(l) the Lescuraea-group from the main part of Leskeaceae; and (2) a group of species belonging to Pylaisia, Homomallium and Hypnum (sections others than sect. Hypnum) from Hypnum sect. Hypnum (with H. cupressiforme as the type of the genus).
