The genus is monotypic, containing the single species Psoromella pampana, a soil-dwelling lichen found in Argentina.

The type specimen was collected at an elevation of about 2,200 m (7,200 ft) above sea level in the Pampas region of Argentina by Carl Curt Hosseus.

[3] The thallus, which forms the main body of the lichen, has a scaly surface texture with individual scales that take on a somewhat rounded shape, measuring 1–2 mm in diameter.

The uppermost cortical layer consists of tightly packed fungal cells forming what is known as paraplectenchymatous tissue.

However, the species was known to produce asexual reproductive cells (conidia), which have a characteristic finger-like (dactylococcoid) shape.
