An arctic-alpine crustose lichen. It has a grey-white granulose thallus and dark, bluish-pruinose apothecia with vanishing margins. Only historical records are known from the Czech Republic, from the colder areas of the Krkonoše Mts and the Kralický Sněžník Mts. It is a relatively inconspicuous species, usually overgrowing mosses (for example the genera Andreaea and Racomitrium) on siliceous rocks or occurring on compact bare soil. Frutidella caesioatra prefers places with long-lasting snow cover. Recently, it has not been reported from the country and it may belong to extinct species in the Czech Republic. The lichen was last reported in 1960 from the Čertova zahrádka ravine in the Krkonoše Mountains and distributed in an exsiccate (Vězda 1961).
