Hyophila Pottiaceae South America Taxonomy Trichostomum Bryophytes

Abstract

The ongoing morphological and molecular analyses of the genus Trichostomum in South America has allowed us to study some specimens from Brazil, Bolivia, and Paraguay that do not match with any Pottiaceae species presently recognized in these countries. We originally identified them as Hyophila loxorhyncha, a neglected taxon known only from the type locality and a few others Brazilian localities. The phylogenetic position of this species is inferred based on the new specimens by the nuclear ITS sequences. This analysis resolves the species in the clade corresponding to the genus Trichostomum, supporting its new combination as T. loxorhynchum. We present a complete description of this species, its distribution map, and its main distinctive morphological characters. Lectotypes are also proposed for Hyophila loxorhyncha and Gymnostomum jamesonii. Trichostomum loxorhynchum is newly reported from Bolivia and Paraguay. The distribution of Tainoa subcucullata is here updated excluding South America.
