''Tortula'' is a genus of mosses in the family Pottiaceae.

Species

There are different classifications for the species included in the genus. The delimitation of genus Tortula is problematic and was subject to a number of alterations in the past. Some species that were earlier placed under ''Desmatodon'', ''Phascum'' and ''Pottia'' have been made part of genus ''Tortula'', while other species that had been formerly placed in this genus became part of ''Hennediella,'' ''Microbryum'' and ''Syntrichia''. The rearrangement of the genus followed new studies in gametophyte characteristics.Wolfgang Frey, Michael Stech, Eberhard Fischer: ''Bryophytes and Seedless Vascular Plants'' (= Syllabus of Plant Families. 3). 13th edition.
