Dufourea ligulata
Species of lichen
Dufourea ligulata is a species of saxicolous (rock-dwelling), foliose lichen in the family Teloschistaceae.[2] The German lichenologist Gustav Wilhelm Körber first formally described the species in 1862, as a member of the genus Physcia.[3] Patrik Frödén, Ulf Arup, and Ulrik Søchting transferred it to the genus Dufourea in 2013 as part of a molecular phylogenetics-based restructuring of the family Teloschistaceae.[4]
The lichen is found in Australasia, usually on coastal rocks. The lobes of its thallus are 5–10 mm long; they are generally longer and narrower than those of other Australian xanthorioid lichens, including X. streimannii, X. parietina, X. filsonii, and X. elixii.[5]
