Halegrapha masoniana

Halegrapha masoniana is a species of corticolous lichen in the family Graphidaceae. Found in Sri Lanka, it was formally described as a new species in 2014 by lichenologists Gothamie Weerakoon, Robert Lücking, and Helge Thorsten Lumbsch. The type specimen was collected from Cottaganga Ella, in a montane forest at an altitude of 1,147 m (3,763 ft). It is only known to occur at the type locality. The specific epithet honours American lichenologist Mason Hale, "for his important contributions to lichenology in Sri Lanka".^[1]
