Abstract

Taxonomic ranks above the species level are inherently arbitrary. However, there is a growing number of publications aiming at more consistent classifications with comparable ranks among taxa. For this study we use a recently developed temporal approach that uses time-calibrated chronograms to identify a temporal bands for order and family ranks in the two major subclasses of Lecanoromycetes, viz. Lecanoromycetidae and Ostropomycetidae. A data set of 2,026 sequences of nuLSU, mtSSU, RPB1, RPB2, and MCM7 of Lecanoromycetes representing 539 taxa was used to address the circumscription of families and orders following the proposed temporal approach. Based on the results of this study, we propose a revised, temporal-based classification for the two subclasses, including all clades that share a common ancestor 176-194 Ma for orders and a time window of 111-135 Ma for families. Most of the currently accepted orders were supported in their current circumscription. Three new orders are proposed: Sporastatiales Lumbsch & Leavitt, Schaereriales Lumbsch & Leavitt, and Thelenellales Lumbsch & Leavitt, whereas Arctomiales, Hymeneliales, and Trapeliales are synonymized with Baeomycetales. Most of the currently accepted families were supported and one new families is proposed: Varicellariaceae, whereas Squamarinaceae and Stereocaulaceae are synonymized with Cladoniaceae, Carbonicolaceae with Lecanoraceae, Letrouitiaceae with Brigantiaeaceae, Lobariaceae and Nephromataceae with Peltigeraceae, Thrombiaceae with Protothelenellaceae, and Miltideaceae with Agyriaceae. The families Diploschistaceae and Thelotremataceae are resurrected.
