A new species of Parmotrema (Parmeliaceae, lichenized Ascomycota) from Cerrado vegetation in the state of Maranhão, Brazil

Abstract A new species of Parmotrema, with medullary lecanoric acid (P. paraisoense), is proposed here. It features a foliose thallus with linear interrupted to subcapitate soralia, occurring mainly on the margins of the lobes. The lobes are 4-8 mm wide, with a ciliate margin, and contain atranorin...

Description
Summary:Abstract A new species of Parmotrema, with medullary lecanoric acid (P. paraisoense), is proposed here. It features a foliose thallus with linear interrupted to subcapitate soralia, occurring mainly on the margins of the lobes. The lobes are 4-8 mm wide, with a ciliate margin, and contain atranorin and lecanoric acid as the main secondary metabolites. This species has a corticolous habit and was found on a fallen tree branch in a cerradão area, a typical vegetation of the Cerrado biome, in the Brazilian state of Maranhão.
