Abstract
The monotypic lichenised genus Anamylopsora (Baeomycetaceae, Baeomycetales), with its single species A.pulcherrima, is distributed in the arid areas of the Northern Hemisphere, including China. In this paper, we introduce another species new to science, Anamylopsorapruinosa. The new species is characterised by a densely pruinose upper surface, abundantly thick and strong rhizines and terricolous habitat. It is also strongly supported by the phylogenetic and species delimitation analyses based on nrDNA ITS sequences, in which A.pruinosa forms well-supported clade separated from A.pulcherrima.
