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 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 .
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]
They surveyed the lichens from many areas throughout the state; one of which was Soldiers Delight. In 1977, they published their results and reported one location for each species of lichen that they identified. Thus, while they may have collected a particular species from numerous places they documented only one.
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.
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 ]
Basidiolichen mycobionts consist of 172 known species (0.9% of the total number of accepted lichen species) across 15 genera, 5 families, and 5 orders within the class Agaricomycetes in the fungal division Basidiomycota. [1] The majority of described basidiolichen mycobionts belong to the genus Cora, followed by the genera Dictyonema and ...
