摘要

The original material of Usnea confusa Asahina consists of several thalli glued on a cardboard. In order to avoid any future taxonomic confusion especially presence or absence of "isidiate soredia", a single specimen with numerous isidiofibrils developing on the soralia was chosen as lectotype. The lectotype of U. confusa contains usnic, salazinic, constictic acids and trace amount of protocetraric acid as the secondary substances. ITS rDNA sequences of Japanese and Taiwanese specimens that have the same morphology and chemistry with the lectotype form two distinct clades nested within the strongly supported clade representing the core group of Usnea cornuta (containing U. cornuta Korber s.str.). Our molecular phylogenetic result based only on ITS rDNA sequences doesn't allow to confirm or contradict the conspecificity of U. confusa with U. cornuta.
