Redonia

Redonia is a genus of lichenized fungi in the family Caliciaceae. It contains the single species Redonia chilena, a squamulose lichen. The type specimen was collected in Tarapacá, Chile, where it was found growing on calcareous soil. The genus was circumscribed in 1973 by Carroll [William Dodge]. The genus name honours Jorge Redón Figueroa, a Chilean lichenologist who collected the type.
In his original circumscription of the genus, Dodge included the species Redonia cladocarpiza, but this species is now known as Tetramelas cladocarpizus.
