Abstract The phylogenetic relationship of lecanoroid lichens is studied using two data sets:1)a 2-locus data set including 251 OTUs representing 150 species,and 2)a 6-locus data set with 82 OTUs representing 53 *** genus Lecanora as currently circumscribed is shown to be highly polyphyletic and several genera,including Adelolecia,Arctopeltis,Bryonora,Carbonea,Frutidella,Lecidella,Miriquidica,Palicella,Protoparmeliopsis,Pyrrhospora,and Rhizoplaca are nested within Lecanora sensu lato.A core group of Lecanora is supported as monophyletic and includes species of the ***,***,and *** groups,and a core group of the *** *** monophyletic clades that are well supported in our analyses and well characterized by phenotypical characters are accepted here:1)Myriolecis to accommodate the Lecanora dispersa group and Arctopeltis;2)Protoparmeliopsis for the *** group;and 3)Rhizoplaca is emended to include three placodioid taxa previously classified in Lecanora(***,***),whereas *** and *** are excluded from *** latter is transferred into *** is strongly supported as a monophyletic *** studies indicate the presence of additional clades of species currently placed in Lecanora sensu lato that warrant taxonomic recognition but additional data will be necessary before the circumscription of these entities is fully understood.37 new combinations are proposed into the genera Myriolecis(30),Protoparmeliopsis(2),and Rhizoplaca(5).
