Two species of Bryaceae are reported as new to the Flora of North America region. Bryum austriacum Köckinger, Holyoak & Suanjak is newly reported here from North America from the White Pine Hollow State Preserve in Iowa and is transferred to Plagiobryum Lindb. This represents a major range extension from the European Alps. Bryum biforme R.S. Williams is newly reported here from North America from Arizona at a high elevation site on Rincon Peak and is transferred to Rosulabryum J.R. Spence. The related Mexican species Bryum richardsii Sharp is also transferred to Rosulabryum. New state records include Gemmabryum exile (Dozy & Molk.) J.R. Spence & H.P. Ramsay from New York, Brachymenium mexicanum Mont. from New Mexico and Texas, G. vinosum J.R. Spence & Kellman from Idaho, Imbribryum torenii J.R. Spence & Shevock from New Mexico, Plagiobryoides renauldii (Röll ex Renauld & Cardot) J.R. Spence from New Mexico, Ptychostomum inclinatum (Sw. ex Brid.) J.R. Spence from New Mexico, P. marratii (Hook. & Wilson) J.R. Spence from Alaska, and P. weigelii (Biehler) J.R. Spence from New Mexico. The new combination Rosulabryum sanguilentum (Renauld & Cardot) J.R. Spence & Brinda is made, replacing R. gemmascens (Kindb.) J.R. Spence.
