Atla tibelliorum

Atla tibelliorum is a rare species of saxicolous (rock-dwelling) in the family Verrucariaceae. First scientifically described in 2016, this crustose lichen is characterised by its pale ochre-coloured body that forms cracked patterns on its substrate, with distinctive reproductive structures embedded within warty protrusions. The species has a highly specialised habitat, occurring only in specific alpine and arctic environments with calcareous conditions, and has been documented in northwestern Finland and Alaska. This uncommon lichen represents one of several rare species found in Finland's largest expanse of calcareous rock, the Toskalharji area....read more on Wikipedia.
