Atla praetermissa
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 . The lichen has a superficial, thin and sometimes mesh-like, crustose thallus that is grey to dark green, sometimes with a brownish tinge. Its ascospores are narrowly ellipsoidal and measure 44.7–49.2 by 19.0–22.4 μm. Atla praetermissa has an unidentified green alga as a photobiont. References
