}}Orthodontiales is a monotypic order of mosses.[1]

Description

Species in the order are acrocarpous or pseudo-pleurocarpous mosses that are epiphytic. They are usually dioecious and have erect setae and capsules with a well-developed operculum. They are characterized as small plants growing loosely on coniferous trees, decaying coniferous wood, or in terrestrial habitats. The order is widespread in tropical and temperate regions.[2]

Classification

The only family in the order is Orthodontiaceae, the placement of which has been subject to much revision. The genus Orthodontium was elevated to family status and was originally associated with the Bryales. The family was then placed in the order Rhizogoniales with Aulacomniaceae and Rhizogoniaceae. Most recently, the family was elevated the order Orthodontiales.[1]

The genera represented by the order are:

  • Orthodontium
  • Orthodontopsis
  • Hymenodon
  • Leptotheca
