Cladonia albonigra

About

Cladonia albonigra is a species of fruticose lichen in the family Cladoniaceae. Found from Alaska to California, this lichen grows in both wet bogs and dry forest floors as long as there is abundant sunlight. The species develops characteristic tiered cup structures that start light-coloured but gradually blacken from the bottom up as the outer layer flakes away. It was first scientifically described in 1996 and has since been found in limited locations in Europe and Russia as well.
