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.
