On the taxonomic status of Isopterygium ambiguum (Hypnaceae, Bryophyta) from Gough Island in the South Atlantic Ocean

A taxonomic reassessment of Isopterygium ambiguum, a moss species endemic to Gough Island, reveals it is conspecific with I. tenerifolium, expanding the known distribution of the latter across the South Atlantic. This finding corrects its taxonomic status and identifies Gough Island as the southernmost occurrence of I. tenerifolium. The study also documents additional collections from Tristan da Cunha and Nightingale Island, contributing to a broader understanding of moss biodiversity in this remote region. Morphological details were illustrated, and distribution patterns were mapped, providing insights into the biogeography of South Atlantic mosses.
