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 .
The lichen was first formally described as a new species by the Swedish lichenologist Erik Acharius in 1799. [3] He classified it in the eponymous genus Lichen, which was standard at the time. In 1803 he transferred it to the genus Parmelia. [4] Ernst Stizenberger transferred it to the genus Anzia in 1862. [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.
Arthonia radiata is a crustose lichen with an immersed thallus, often separated from its surroundings by a thin brown line.The thallus is typically pale, ranging from white to pale grey, sometimes with a brown or olive tinge, and often forms a mosaic-like pattern on its substrate.
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 ...
The cross-taxon analysis approach has shown that lichen abundance and diversity significantly influence the diversity patterns of lichenicolous fungi. This method has demonstrated that lichen communities can serve as reliable surrogates for predicting lichenicolous fungal diversity, aiding in the conservation and study of these specialised fungi.
Chaenotheca is a genus of lichenized fungi within the family Coniocybaceae. [1] The sexual reproduction structures are a mass of loose ascospores that are enclosed by a cup shaped exciple sitting on top of a tiny stalk, having the appearance of a dressmaker's pin (called a mazaedium), hence the common name pin lichen.
