Resumo: The classification of the Bryopsida (mosses) has been based primarily on the variation of sporophytic characters i.e., architectural features of the peristome teeth that line the capsule mouth. Five arthrodontous peristome types have been recognized. Whether peristome types define natural groups and how they are evolutionary related has, however, remained unclear. Nucleotide sequence data from one nuclear and two chloroplast loci are generated and compiled to test two contrasting hypotheses regarding the ancestral peristome type in the Arthrodonteae. The genomic data partitions are incongruent with regard to the phylogenetic signal they carry. All phylogenetic analyses converge toward the polyphyly of the Funariineae and the Funariaceae. The Funariaceae are defined by the loss of a codon in the rps4 gene. Goniomitrium acuminatum, the type of the genus, lacks this deletion, and is always resolved within the Haplolepideae.
