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]
Lepraria finkii is a type of lichen in the genus Lepraria. [1] Its colours range from a greenish-gray to a bluish-green. The organism is generally found everywhere in the world, but more commonly found in tropical areas; it can be spotted in shaded areas on tree trunks, overtaking bryophytes, in soil banks, and in dry niches.
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 .
It was in 1869 that Simon Schwendener demonstrated that all lichens were the result of fungal attack on the cells of algal cells and that all these algae also exist free in nature. This researcher was the first to recognise the dual nature of lichens as a result of the capture of the algal component by the fungal component. [ 19 ]
A lichen can be described as all of the following: Life form – an entity that is alive.; Composite organism – a symbiotic life form composed of multiple partners from different biological domains, families and kingdoms, and from different phyla, classes and divisions within those domains and kingdoms.

Dirinaria confusa exhibits foliose thalli, which are approximately pressed and loosely pressed at the tips of lobes, with a maximum diameter of up to 8 cm.The lobes display a pinnate or subpinnate lobate structure, spreading out and merging, typically flat or convex but occasionally concave towards the tips, measuring between 0.2 and 3 mm wide.
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.
