The Rhizogoniaceae, Aulacomnium, Calomnion and Orthodontium are the nearest relatives of the Hypnidae and hypnodendroid mosses ... 

Additionally, they found clades within the rhizogonian grade (Aulacomnium, Calomnion and Orthodontium inclusive) that include both pleurocarpous and non-pleurocarpous taxa, raising the interesting possibility that pleurocarpy either originated more than once or that it was lost by reversion to acrocarpy. 

In summary, it appears from previous studies that Aulacomnium, Calomnion, Orthodontium, Rhizogoniaceae, the hypnodendroid mosses and Hypnidae should be the continued focus of attention for understanding the distribution of pleurocarpy within the bryalean mosses, and understanding a majority of the species richness of mosses.

Specialization for substrate preference may be one cause of low diversity in rhizogonian mosses. Within the group, 19 of 34 species and 5 of 11 genera (excluding Orthodontium) have a substrate preference of tree fern trunks (compare ecological descriptions in Scott and Stone, 1976 Churchill and Buck, 1982 Beever, 1984 Koponen et al., 1986 Karttunen and Back, 1988 Beever et al.. 

Pleurocarpy/non-pleurocarpy sensu Newton and De Luna (1999) was optimized onto one of the 24 most parsimonious trees (henceforth referred to as tree A) obtained from the molecular analysis in Bell and Newton (2004). In addition, the effects on optimization of using a slightly different topology (tree B), in which Leptotheca gaudichaudii is sister to Orthodontium lineare (as in the maximum likelihood tree in Bell and Newton, 2004), were explored. No other conflicts between topologies obtained under parsimony and likelihood criteria in Bell and Newton (2004) signiflcantly...
