The Dicranidae are a widespread and diverse subclass of mosses in class Bryopsida, with many species of dry or disturbed areas. They are distinguished by their spores; the peristome teeth are haplolepideous with a 4:2:3 formula, and an exostome is absent. [1]
Traditionally, the Dricanidae comprised about six to eight orders [1] [2] . However, phylogenetic analysis using molecular markers suggested that Dicranales was paraphyletic with respect to Pottiales. [2] [3]
A recently phylogenomic analysis led to a break-up of Dicranales and creation of a number of new small orders. [3] The phylogenetic relationships recovered within Dicranidae are shown in the cladogram below. The orders Bryoxiphiales, Pseudoditrichales and Mitteniales were not sampled in this study.

The Bryopsida constitute the largest class of mosses, containing 95% of all moss species. It consists of approximately 11,500 species, common throughout the whole world.
Grimmiales is an order of mosses in the subclass Dicranidae. It comprises four families: Grimmiaceae, Ptychomitriaceae, Seligeriaceae, and Saelaniaceae.
Pottiales is an order of mosses in the subclass Dicranidae.
Bryales is an order of mosses.
Dicranales is an order of haplolepideous mosses in the subclass Dicranidae.
Fissidentaceae is a family of haplolepideous mosses (Dicranidae) in the order Dicranales, with a single genus, Fissidens. It was formerly placed in the now-obsolete order Fissidentales.
Eustichia is the only genus of moss in family Eustichiaceae. The family was previously place in the order Dicranales, but is now placed in its own monotypic order, Eustichiales.
Leucobryaceae is a family of haplolepideous mosses (Dicranidae) in the order Dicranales.
Bruchiaceae is a family of haplolepideous mosses in subclass Dicranidae. The family was previously placed in the order Dicranales, but are now placed in their own monotypic order, Bruchiales.
Ptychomitriaceae is a family of mosses in the subclass Dicranidae.
Pseudoditrichales is an order of haplolepideous mosses in the subclass Dicranidae. It comprises two families, Pseudoditrichaceae and Chrysoblastellaceae. Pseudoditrichaceae was previously placed in Bryales, while Chrysoblastellaceae is a new family erected for Chrysoblastella, which was previously placed in Ditrichaceae.
Erpodiaceae is a family of haplolepideous mosses in subfamily Dicranidae. It was formerly placed in order Dicranales, but is now placed in its own monotypic order, Erpodiales.
Ditrichaceae is a family of haplolepideous mosses in subclass Dicranidae. The family was previously place in order Dicranales, but it now placed in its own monotypic order, Ditrichales.
Calymperaceae is a family of haplolepideous mosses (Dicranidae) in the order Dicranales.
Distichium is a genus of haplolepideous mosses (Dicranidae) in the monotypic family Distichiaceae.
Timmiellaceae is a family of haplolepideous mosses (Dicranidae). It contains two genera, Luisierella and Timmiella, that were formerly place in family Pottiaceae.
Catoscopium is a genus of haplolepidous mosses (Dicranidae) in the monotypic family Catoscopiaceae .
Saelania is a genus of mosses in the monotypic family Saelaniaceae in subclass Dicranidae. The genus was previously placed in family Ditrichaceae. Saelania is named after Finnish botanist Thiodolf Saelan.
Mittenia is a genus of haplolepideous mosses (Dicranidae) with a single species, Mittenia plumula, which is the sole representative of the family Mitteniaceae. The family was previously placed in the order Pottiales, but is now placed in its own monotypic order, Mitteniales.
Rhabdoweisiales is an order of haplolepideous mosses in the subclass Dicranidae. Its two families, Rhabdoweisiaceae and Rhachitheciaceae, were previously placed in Dicranales.
