Cladonia krogiana

Species of lichen

Cladonia krogiana is a species of fruticose lichen in the family Cladoniaceae, described to science in 2002. This lichen is characterised by its greyish-green to medium-brown squamulose (scaly) primary thallus, forming cushions up to 10 cm (4 in) wide, with distinctive chemical components including barbatic acid and the rare xanthone compound chlorovinetorin. Originally discovered in southeastern Norway, C. krogiana has since been found in the Czech Republic and New Brunswick, Canada, typically growing on sun-exposed siliceous rock in periodically wet, open areas near forests and water bodies.
