[1] The genus was circumscribed in 2020 by lichenologists Sergey Kondratyuk, László Lőkös, and Edit Farkas, with Pisutiella conversa assigned as the type species.

When the thallus of Pisutiella is fully developed it is characteristically thick with a well-formed cortical layer, although it does not produce vegetative diaspores.

[2] Chemically, the thallus usually does not react to potassium hydroxide (i.e., the K spot test), or in rare instances, the cortical layer may show a light pink reaction.

While the content of anthraquinone in the apothecial disc is often not investigated, lichen products such as parietin, emodin, and fallacinal have been documented in some Pisutiella species.

Pisutiella species are found primarily on scattered boulders rich in bases or containing lime in siliceous rocks, and occasionally on dense limestone and dolomite.
