Micarea lignaria is a small crustose lichen with granular thallus and tiny grey-green apothecia, adapted to wood and bark substrates. It grows on bare acidic bark, wood, and sometimes peat in temperate and boreal forest environments. This photosynthetic lichen obtains energy through its algal partner and contributes to wood surface colonization.

Micarea lithinella is a small crustose lichen with a pale granular thallus forming minute apothecia on rock surfaces. It inhabits siliceous rock faces and stone walls in cool temperate and montane environments across Europe. This lichen colonizes bare, acidic rock surfaces and weathered mineral substrates.
