TY - JOUR A1 - Frahm, Jan-Peter T1 - The taxonomic status of Bryum arachnoideum C. Müll. and B. lanatum (P. Beauv.) Brid. T2 - Tropical bryology N2 - A study of an isotype of Bryum arachnoideum C. Müll., a poorly understood species described from tropical Africa, revealed that this species is distinct from B. argenteum Hedw. var. lanatum (P. Beauv.) Hampe. The differences between both species are listed. All specimens from tropical Africa named as B. arachnoideum by the author must be attributed to B. argenteum var. lanatum. The differences between B. argenteum var. argenteum and var. lanatum, both morphologically and ecologically, are so important that it is proposed to treat var. lanatum on a species level as B. lanatum (P. Beauv.) Brid.
