Canoparmelia amazonica, Myelochroa lindmanii and Parmelinella salacinifera belong to Parmelinella (Parmeliaceae)

Abstract

Abstract. The lichen family Parmeliaceae is among the best studied groups of lichens. Canoparmelia amazonica, Myelochroa lindmanii, and Parmelinella salacinifera are species of Parmeliaceae that have yet to be studied in detail with molecular methods. This study used analyses of ITS sequences to examine the phylogenetic position of these three species. Canoparmelia amazonica and M. lindmanii were recovered within Parmelinella rather than the genera to which they are currently assigned. While for the P. salacinifera we confirmed its phylogenetic position within the genus. Chemical and morphological descriptions of species are provided, generic placement is discussed, and new combinations are proposed as needed. These results highlight the need for morphological revision of the delimitation of Parmelinella, a small genus of Parmeliaceae that has been considered well-defined morphologically and is phylogenetically closely related to Bulbothrix s.l.
