Lecanora vainioi
Lecanora vainioi is a species of crustose lichen in the family Lecanoraceae. It is found in Brazil, where it grows on granitic rocks. It was described as a new species in 1986 by Finnish botanist Heino Vänskä. The epithet vainioi honours lichenologist Edvard Vainio, who did pioneering work on the Brazilian lichens.
Description
The crust-like thallus of Lecanora vainioi ranges in colour from yellowish-white to very pale yellowish grey. The areolae are initially tightly attached and cushion-shaped, but later merge so that the crust surface becomes irregularly wrinkled and partly rimose.Secondary chemicals produced by the lichen include atranorin, epinorin, and zeorin.
