In this paper the chromosome numbers of 8 species are reported. The results are as follows: Pleurozium schreberi (Brid.) Mitt., n=5; Hyolcomium splendens (Hedw.) B.S.G., n=11; Thuidium recognitum (Hdew.) Lindb., n=11; T. assimile (Mitt.) Jaeg, n=11; Tetraphis pellucida Hedw., n=8; Plagiomnium maximoviczii (Lindb.) Kop., n=6;P. cuspidatum (Hedw.) Kop., n=12; Mnium marginatum (With.) Beauv., n=6. The chromosome number of Thuidium assimile is reported for the first time and Pleurozium schreberi, Hylocomium splendens , Thuidium recognitum, Tetraphis pellucida are reported for the first time in China.
