Parmotrema lichexanthonicum Eliasaro & Adler (1997)

Parmotrema lichexanthonicum is a species of foliose lichen in the family Parmeliaceae. Found in Brazil, it was formally described as a new species in 1997 by Sionara Eliasaro and Mónica Adler. The type specimen was collected by the first author from the Serra do Cipó ( Santana do Riacho, Minas Gerais); here the lichen was found growing on a rock. The specific epithet lichexanthonicum refers to the presence of the secondary compound lichexanthone in the medulla of the lichen. [1] Other compounds in the lichen are the depsidone salazinic acid (found in the medulla), and the depside atranorin (found in the cortex). [2] A close relative to this species is Parmotrema ultralucens, which contains the same cortical and medullary metabolites. [1]
