Abstract
Abstract The species of Heterodermia in Brazil have been revised based on literature reports, public databases and examination of 500 recent specimens from 15 states. So far, 43 species have been reported in the literature, two of which are not accepted here. We report 10 additional species from Brazil and describe 15 new to science, mostly from the Atlantic rainforest biome, raising the total number to 68, including two still undescribed species from Santa Catarina State. A key to all accepted species is given, keying out more species than represented in any previously published key of the genus. Based on new phylogenetic work, we do not accept the split genera that were recently proposed. We do informally recognize an additional group, the H. dactyliza-group. The following species are described as new: Heterodermia amphilacinulata M. F. N. Martins & M. P. Marcelli, H. caneziae M. F. Souza & Aptroot, H. delicatula M. P. Marcelli & M. F. N. Martins, H. dissecticodiademata M. F. Souza & Aptroot, H. dissecticoflabellata M. F. Souza & Aptroot, H. flavodactyliza M. F. Souza & Aptroot, H. flavulifera M. F. Souza & Aptroot, H. labiata M. P. Marcelli & M. F. N. Martins, H. macrosoraliata M. P. Marcelli & M. F. N. Martins, H. minor M. F. Souza & Aptroot, H. neocrocea M. F. Souza & Aptroot, H. nigromarginata M. F. Souza & Aptroot, H. phyllalbicans M. F. Souza & Aptroot, H. spielmannii M. F. Souza & Aptroot and H. sublinearis M. P. Marcelli & M. F. N. Martins. The following new combinations are also proposed: Heterodermia africana (Kurok.) M. F. Souza & Aptroot and H. borphyllidiata (Kalb & Meesim) M. F. Souza & Aptroot. Dissectic acid was found in species belonging to three different groups and was not restricted to (and characteristic of) one subgroup, as previously reported.
期刊介绍：
The Lichenologist is the premier scientific journal devoted exclusively to the study of lichens worldwide. As the leading forum for the dissemination of new concepts and topical reviews, The Lichenologist reaches more scientists concerned with the study of lichens and lichen symbionts than any other single journal. All aspects of lichenology are considered including systematics and phylogenetics; molecular biology; ultrastructure, anatomy and morphology; secondary chemistry, effects of pollutants and use as bioindicators; biogeography. In addition to standard length research papers, the journal also publishes Short Communications and Book Reviews. A monthly issue may occasionally be devoted to papers deriving from a symposium.
