Data from: Herteliana schuyleriana (Squamarinaceae), a new crustose lichen widespread in the Appalachian Mountains of eastern North America

Herteliana schuyleriana is described as new to science based on
collections from throughout the Appalachian Mountains of eastern North
America. Taxonomic placement is inferred from molecular phylogenic
analysis of mtSSU sequence data that recovered the taxon as sister to the
type species of Herteliana, H. gagei, and strongly supported these taxa as
embedded within the Squamarinaceae. The new species is characterized by
its occurrence on non-calcareous shaded rocks in inland forested habitats
(vs. exposed maritime oceanic habitats), its greenish-blue crustose
thallus, presence of abundant blastidia on the thallus surface, frequent
sterility, and by the production of roccellic/angardianic acid together
with occasional trace amounts of psoromic acid as accessories to
atranorin.
