Pleurozium schreberi (Musci, Hylocomiaceae) recorded for tropical Africa and a review of its world distribution

The occurrence of the common Holarctic moss species Pleurozium schreberi (Brid.) Mitt. in tropical Africa is confirmed. The species was recorded twice in the Bale Mountains in central Ethiopia by Sabine and Georg Miehe in the upper montane PhilippiaHagenia forest at an elevation of 3 300–3 500 m. The global range of the species is discussed, with special reference to North America, and mapped. Cuspidaria morenoi Müll. Hal. from western Patagonia is briefly assessed and it is suggested that this species should be considered conspecific with Acrocladium auriculatum (Mont.) Mitt., not with Pleurozium schreberi (Brid.) Mitt.
