ABSTRACT
A crustose lichen species new to science – previously characterized in the literature
but unnamed – is formally described. This new species, Chrysothrix bergeri sp. nov.,
ranges from the southeastern United States southwards to the Caribbean islands (Bahamas
and Cuba) and eastwards to Bermuda. It is most easily confused with C. xanthina, from
which it differs in both chemistry and ascospore shape. Bilimbia aurata and Bilimbia stevensoni
are both confirmed as synonyms of C. xanthina. A lectotype is selected for Bilimbia
aurata. Solvent E is recommended for the chromatographic separation of leprapinic and
pinastric acids – two lichen secondary products critical for diagnosing certain species of
Chrysothrix, including C. bergeri.
