Atla praetermissa is a species of saxicolous (rock-dwelling) crustose lichen in the family Verrucariaceae.

Found in Scandinavia, it was formally described as a new species in 2008 by Sanja Savić and Leif Tibell.

The type specimen was collected in Andersjöåforsen (Funäsdalen, Härjedalen Municipality, Sweden).

In addition to Sweden, it has also been recorded in Norway; it grows on calcareous rocks near streams at altitudes ranging from 165 to 955 m (541 to 3,133 ft).

The lichen has a superficial, thin, and sometimes mesh-like crustose thallus that is grey to dark green, sometimes with a brownish tinge.
