Atla wheldonii is a species of terricolous (ground-dwelling), crustose lichen in the family Verrucariaceae.
Found in Europe, it was formally described as a new species in 1947 by William Gladstone Travis from specimens collected from sand dunes in Lancashire, England, in 1924.
[2] Sanja Savić and Leif Tibell transferred the taxon to genus Atla in 2008 following molecular phylogenetic analysis that showed that it, along with three other Northern European species, comprised a distinct clade in the Verrucariacae.
[3] In additional to the British Isles, Atla wheldonii has also been recorded in the Pyrenees,[4] Austria,[5] and Scandinavia.
It grows on basic soil, usually alongside mosses and cyanobacteria; typical lichen associates include Thelocarpon impressellum and Solorina spongiosa, and sometimes Polyblastia helvetica.
