Since Bryhnia Kaurin (Bryophyta: Brachytheciaceae) has been reduced to a synonym of Brachythecium Schimp. s. str., the genus does not exist yet. In this paper, five species of Bryhnia distributed in China were revised. Results are as follows: B. hultenii E. B. Bartram, B. novaeangliae (Sull. & Lesq.) Grout and B. trichomitria Dixon & Thér. are transferred into Brachythecium s. str. as Brachythecium hultenii (E. B. Bartram) Min Li & Y. F. Wang, B. novaeangliae (Sull. & Lesq.) A. Jaeger and B. trichomitrium (Dixon & Thér.) Huttunen, Ignatov, Min Li & Y. F. Wang; Bryhnia brachycladula Cardot is transferred into Myuroclada Besch. and reduced to a synonym of M. longiramea (Müll. Hal.) Min Li, Y. F. Wang, Ignatov & Huttunen; Bryhnia serricuspis (Müll Hal.) Y. F. Wang & R. L. Hu is transferred into the genus Pseudokindbergia Min Li, Y. F. Wang, Ignatov & B.C. Tan. and treated as a synonym of P. dumosa (Mitt.) Min Li, Y. F. Wang, Ignatov & B. C. Tan.
