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. [2] [3] [4]
The lichen's reproductive structures, or ascomata, are usually brightly coloured, and typically in the form of an apothecium – a wide, open, saucer-shaped or cup-shaped fruit body. In most species, these apotheciate ascomata have a lecanorine form, in which the apothecial disc is surrounded by a pale rim of tissue known as a thalline margin .
List of lichen products; Chemical spot tests on the foliose lichen Punctelia borreri showing thallus (top) and medulla (bottom). The pinkish-red colour change of the medulla in the C and KC tests indicate the presence of gyrophoric acid, a chemical feature that helps to distinguish this lichen from similar species in the same genus.

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 ...
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]
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.
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.
