Xanthoparmelia cumberlandia is a lichen which belongs to the Xanthoparmelia genus. It is also known as a member of the rockfrong lichens due to its coloration.
This lichen grows to around 6âÂÂ12 cm in diameter with irregular lobate lobes. The upper surface of the lichen has rounded lobed tips with yellow-green or blueish green areas on the surface.
It is commonly found attached to acid rocks in sheltered and semi-sheltered open coastal and intermontane areas at lower elevations. As such, it is commonly found in across North America, except in deserts and open plains.
Xanthoparmelia cumberlandia produces constictic, norstictic, stictic, norstictic, usnic and menegazzic acids.
The lichen was first formally described under the name Parmelia cumberlandia in 1847.
