Oxneriaria is a genus of lichen-forming fungi in the family Megasporaceae. It has nine species, all of which are saxicolous (rock-dwelling), crustose lichens. Oxneriaria is morphologically similar to Aspicilia, but differs from this genus in its mostly radiating thallus with either a wrinkled or lobate zone around the margins, in its generally smaller ascospores, and in the presence of the lichen product substictic acid. Species in the genus have a polar and arctic–alpine distribution.[1]
The genus was circumscribed in 2017 by Sergey Kondratyuk and László Lőkös to contain species formerly in the Aspicilia mashiginensis species group.[1] This species, now the type of the genus, was first described scientifically by Alexander Zahlbruckner as Lecanora mashiginensis.[2] The genus name honours Ukrainian lichenologist Alfred Oxner, who, according to the authors, "provided important contribution [sic] to taxonomy of aspicilioid lichens and to biodiversity of polar lichens".[1]
