This study provides new insights on the phylogenetic position of the lichenicolous fungal genus Abrothallus based on six molecular markers(nuSSU,nuLSU,mtSSU,RPB1,RPB2 and TEF-α).In a broad-scale analysis,we detected high support for inclusion of the genus within Dothideomycetes.A further analysis provided support for Abrothallus as a member of the subclass Pleosporomycetidae as a sister group of Jahnulales,an order of aquatic *** the exclusive characters of this group of apotheciate fungi within the Dothidiomycetes,a new monotypic order Abrothallales is here introduced together with the new family *** a multi-locus analysis(based on the six loci indicated above plus ITS)restricted to 12 putative Abrothallus species,two clearly separated clades were observed:one comprising species growing on lichens of the families Parmeliaceae and Ramalinaceae,and the second including species that live on lichens of the order Peltigerales and the family Cladoniaceae.

The phylogeny of the Acarosporaceae(Lecanoromycetes,Acarosporomycetidae,Acarosporales)is investigated using data from three molecular markers;nuclear ITS-LSU rDNA,mitochondrial SSU andβ-*** is shown to be constituted by six main clades;Myriospora,Timdalia,Pleopsidium,a clade composed by BAcarospora^rhizobola and BA.^terricola,the poorly supported Sarcogyne clade(including several Polysporina and Acarospora species)and the Acarospora clade(including the type of Polysporina,***,and several other Polysporina species).The common ancestor of the Acarosporaceae did not produce strongly black pigmented(carbonized or melanized)ascomata,but this trait has arisen secondarily and independently numerous times in the evolution of the *** number of changes in character states of both carbonized epihymenium and carbonized exciple are considerably more than the minimum *** genera Sarcogyne and Polysporina—largely circumscribed based on the presence of black pigmented ascomata—are shown to be distinctly *** presence of green algae in the ascoma margin(lecanorine or lecideine ascomata)may vary even within single species.
