[2] The genus was circumscribed by Patrik Frödén, Ulrik Søchting, and Ulf Arup in 2013, as part of a molecular phylogenetics-led restructuring of the Teloschistaceae.

Most other species in this genus have a rounded exterior that is usually covered with a protective layer, devoid of hair-like structures.

This protective layer has a complex cellular structure (known as "scleroprosoplectechymatous") and often features large, light patches.

Its spores have a unique developmental process, are generally oval in shape, and have short to medium dividing lines (septa.

Additionally, the lichen has large, protruding structures (pycnidia) that produce spore-like cells (conidia).
