Molecular phylogenetic analysis of
nuclear ITS and plastid rps4–trnS found species of the genus Claopodium
in the clade formed by species of Brachytheciaceae and Meteoriaceae, including
Trachypodaceae. Claopodium is resolved as sister to Brachytheciaceae,
thus we suggest its placement in this family, despite it will be the only taxon
of the family with pluripapillose laminal cells. The taxonomic value of the
papillose leaf cells in pleurocarpous mosses is discussed.
