ABSTRACT Introduction The bryophytes of Ghana are under-recorded, but the country has several important and relatively extensive examples of West African forest likely to support an interesting flora. Of these, Atewa Forest was targeted for survey in 2014, resulting in many records, including 58 taxa new to Ghana. This paper reports the results of further fieldwork, both in Atewa and elsewhere, in 2017, and makes some necessary additions and amendments to previously published data. Methods Bryophyte fieldwork was carried out in key forest sites in southern Ghana during November 2017, and was followed by targeted herbarium studies. Key results A new species, Cololejeunea ankasica, is described, and a new site for the rare Ghanaian endemic C. calcarata reported; a further 27 taxa new to Ghana are recorded, and amendments made to previously published information. Conclusions This study shows that even lowland areas of remaining forest in Ghana are bryologically interesting and that bryophytes are an important but still under-recorded part of Ghana’s biodiversity. It also strengthens the case for National Park status for Atewa Forest, which remains the only known site in Ghana for many species characteristic of higher altitude forest.
