Abstract

Ochyra, R. & Plášek, V. 2019. On the taxonomic status of Isopterygium ambiguum (Hypnaceae, Bryophyta) from Gough Island in the South Atlantic Ocean. - Herzogia 32: 357-368.

The original material of Isopterygium ambiguum, a species known only from the type collection from Gough Island in the South Atlantic Ocean, is taxonomically assessed and some details of its morphology are illustrated. The species is conspecific with the Afro-American I. tenerifolium. The global distribution of I. tenerifolium is reviewed and mapped and the locality on Gough Island represents its southernmost known occurrence. In addition, the species is known from several collections from Tristan da Cunha and Nightingale Island. The distribution patterns of the South Atlantic mosses are briefly discussed.
