Data from: Lecanora layana (Lecanoraceae), a new sorediate species widespread in temperate eastern North America
Lecanora layana is described as new to science based on collections from throughout temperate eastern North America. The species is sorediate and both morphologically and chemically similar to L. nothocaesiella, differing in the production of stictic acid in addition to atranorin and zeorin. As apothecia are unknown in L. layana, the hypothesized generic placement and relationship with L. nothocaesiella were confirmed with molecular phylogenetic analyses of mtSSU sequence data.

Values at each node indicate non-parametric-bootstrap support; only support values > 50% are indicated B Box plots of ITS genetic distances within each new species, all intraspecific distances, and all interspecific distances. In each box plot, the box shows the interquartile range (IQR) of the data. The IQR is defined as the difference between the 75th percentile and the 25th percentile. The solid and dotted line through the box represent the median and the average length, respectively; and C The coalescent-based species-tree for the Rhizoplaca melanophthalma species-complex estimated from five genetic markers (ITS, IGS, group I intron, β-tubulin, and MCM7 loci) in Leavitt et al. 2011a.
