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.
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.
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.
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 ...
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.
A fruticose lichen may have flattened "branches", appearing similar to a foliose lichen, but the underside of a leaf-like structure on a fruticose lichen is the same color as the top side. The leaf-like lobes of a foliose lichen may branch, giving the appearance of a fruticose lichen, but the underside will be a different color from the top side.
Thalli are much thinner in shady locations than in those exposed to full sunshine; this has the effect of protecting the algae that cannot tolerate high light intensities. The lichen pigment parietin gives this species a deep yellow or orange-red color. [6] Xanthoria parietina prefers growing on bark and wood; it is found more rarely on rock. [5]
Placopsis (bullseye lichen) [2] [3] is a genus of lichenized fungi in the family Trapeliaceae. [4] Species.
