The lichen was first described scientifically as Capitularia amaurocraea in 1810. It was transferred to the genus Cladonia in 1887.[3] It is commonly known as quill lichen.[4]
The thallus of Cladonia amaurocraea comprises tall (15–100 mm high) and slender podetia that are irregularly or dichotomously branched. These podetia have a smooth, yellowish-green surface that is often mottled with patches of green and white. They either form a pointy tip, or a narrow cup that is either closed or has a narrow opening. The cortex contains usnic acid, while the medulla has barbatic acid.[4]
Cladonia amaurocraea is found in boreal forests, where it typically grows on talus deposits between boulders and on rocky ground. In North America, it is widespread throughout Canada and Alaska.[4]
