List of lichen products Chemical spot tests on the foliose lichen Punctelia borreri showing thallus (top) and medulla (bottom).

But sometimes the parts of a lichen species common name are common names of other lichen genera. For example, Psilolechia lucida, in the genus Psilolechia, is commonly called "sulphur dust lichen". [1] [2] But "sulphur lichen" refers to the genus Fulgensia, and "dust lichen" refers either to the genus Chrysothrix or the genus Lepraria. [1] [3 ...
The lichen was first formally described as a new species by the Swedish lichenologist Erik Acharius in 1799. [3] He classified it in the eponymous genus Lichen, which was standard at the time. In 1803 he transferred it to the genus Parmelia. [4] Ernst Stizenberger transferred it to the genus Anzia in 1862. [5]
In North America, one vernacular name for the lichen is pink bull's-eye lichen. [ 4 ] Placopsis lambii is distinguished by its placodioid thallus that features deeply notched and radiating edge lobes , a glossy upper surface, typically dark and somewhat rounded soralia , and non-lobate cephalodia that may be absent in certain samples.
Buellia aethalea is a species of lichen that belongs to the family Caliciaceae. [2] It is commonly known as darkened button lichen, [3] [4] and Buellie noircie in French. [1] The lichen's familiar nickname is inspired by the appearance of its surface, adorned with small black spots reminiscent of buttons. [5]
