Teloschistes chrysophthalmus, sometimes referred to as the gold-eye lichen or golden-eye, is a fruticose lichen with branching lobes. Their sexual structures, apothecia , are bright-orange with spiny projections ( cilia ) situated around the rim.
The first members of the present-day Teloschistaceae to be formally described were the common sunburst lichen (Xanthoria parietina) and the gold-eye lichen (Teloschistes chrysophthalmus). These were two of several dozen lichen species described by the Swedish taxonomist Carl Linnaeus , the former in his influential 1753 treatise Species ...
It has wide distribution, and many common names such as common orange lichen, yellow scale, [2] maritime sunburst lichen and shore lichen. It can be found near the shore on rocks or walls (hence the epithet parietina meaning "on walls"), [ 3 ] and also on inland rocks, walls, or tree bark. [ 4 ]
Vulpicida canadensis, the brown-eyed sunshine lichen, [2] is a species of foliose lichen in the family Parmeliaceae. [3] It is endemic to northwestern North America where it grows as an epiphyte on the bark and wood of conifer trees.
This is possible due to the action of lichen phenolics such as usnic acid derivatives. [34] From the 1950s the lichen product usnic acid was the object of most antitumour research. These studies revealed some in vitro antitumour activity by substances identified in two common lichens Peltigera leucophlebia and Collema flaccidum. [35]

The cross-taxon analysis approach has shown that lichen abundance and diversity significantly influence the diversity patterns of lichenicolous fungi. This method has demonstrated that lichen communities can serve as reliable surrogates for predicting lichenicolous fungal diversity, aiding in the conservation and study of these specialised fungi.
