Tholurna is a genus of lichenizedfungi in the family Caliciaceae.[2] The genus is monotypic, containing the single species Tholurna dissimilis. This species was first described by Johannes Musaeus Norman as Podocratera dissimilis in 1861; he circumscribed the new genus Tholurna the same year to contain the species. It is found in Scandinavia and western North America.[3]
