Thrombium epigaeum (Pers.) Wallr.

A terricolous lichen, the thallus is subgelatinous when wet and has a characteristic pale ochraceous colour due to Leptosira photobionts. Perithecia are black, submersed, only visible as dark dots. Spores are simple.

Thrombium epigaeum is an early colonizer of sandy and clayey soils, contributes to stabilization of the upper soil surface. It is rare to scattered, but can be locally abundant. It is found from lowlands to mountains, most commonly on anthropogenic substrates (road and railway notches, sand quarries, ground prepared for construction works etc), but also on natural substrates (root plates of wind-blown trees, eroding slopes, etc).
