[2] It has a wide distribution in Europe and North America, and has also been recorded in China.

In 1985, Susan Meyer transferred it to Imshaugia, and assigned it as the type species of that newly circumscribed genus.

[5] The lichen has a whitish to pale gray thallus comprising lobes measuring 0.5–1.2 mm wide.

The thallus undersurface is tan to whitish, and numerous short brown rhizines serves as holdfasts that attach the lichen to its substrate.

Infection by the fungus results in the formation of small amber-coloured basidiomata on the thallus surface.
