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 was first formally described in 1933 by the Finnish lichenologist Veli Räsänen; he named it as a variety of Cetraria juniperina (now Vulpicida juniperinus). Räsänen distinguished his new variety from typical C. juniperina by several features: its erect thallus with obtuse lobes , bright golden-yellow colour, reticulate-veined ...
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 .
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]
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.

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.
Xanthoria ulophyllodes Räsänen (1931) – powdery sunburst lichen [6] Xanthoria whinrayi S.Y.Kondr. & Kärnefelt (2007) Xanthoria yorkensis S.Y.Kondr. & Kärnefelt (2009) The taxa Xanthoria coomae S.Y.Kondr. & Kärnefelt (2007) and Xanthoria polessica S.Y.Kondr. & Yatsyna (2013) were determined to be the same species as X. parietina in a 2020 ...
