Physcia magnussonii

Species of lichen

Physcia magnussonii is a species of saxicolous (rock-dwelling), foliose lichen in the family Physciaceae. It was formally described as a new species in 1952 by the Swiss botanist Eduard Frey. He collected the type specimen in Bern, Switzerland. The species epithet honours the Swedish lichenologist Adolf Hugo Magnusson. Frey's original specimen was later declared the lectotype of the species by Roland Moberg in a 1977 monograph on the genus Physcia.
