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.[2] The species epithet honours the Swedish lichenologist Adolf Hugo Magnusson.[3] Frey's original specimen was later declared the lectotype of the species by Roland Moberg in a 1977 monograph on the genus Physcia.[4]
Physcia magnussonii has a heteromerous and dorsiventral thallus with narrow lobes that form tightly packed, circular rosettes. The lichen produces apothecia (fruiting bodies) with club-shaped asci containing eight ascospores, and also produces pycnidia with asexual conidia, with chemical properties including the presence of atranorin.
