Bryological and Lichenological Section/ABLS McMullin, Troy [1], Steeves, Royce [1], Newmaster, Steven [1]. Bryoria is polyphyletic: two new Sulcaria species combinations inferred from morphology, molecules and metabolites. In 1971, the lichen genus Sulcaria was described from Asia based on two species with long pseudocyphellae that become furrowed, often exposing the medulla. Two additional species were since added to the genus from the west coast of North America, which also have long and furrowed pseudocyphellae. When the very similar genus Bryoria was described in 1977 it contained two species that had long pseudocyphellae, but they were not particularly furrowed, Bryoria pseudocapillaris and B. spiralifera. The generic placement of these two uncommon species was not certain. We provide evidence from morphology, chemical metabolites, and phylogenetic support from three nuclear loci that these two species most recently diverged from Sulcaria instead of Bryoria, necessitating a re-combination.
