Oxneriaria Nikrapensis
''Oxneriaria'' is a genus of lichen-forming fungi in the family Megasporaceae. It has nine species, all of which are saxicolous (rock-dwelling), crustose lichens. The genus was circumscribed in 2017 by Sergey Kondratyuk and László Lőkös to contain species formerly in the ''Aspicilia mashiginensis'' species group. This species, now the type of the genus, was first described scientifically by Alexander Zahlbruckner as ''Lecanora mashiginensis''. The genus name honours Ukrainian lichenologist Alfred Oxner, who, according to the authors, "provided important contribution '' ic' to taxonomy of aspicilioid lichens and to biodiversity of polar lichens". ''Oxneriaria'' is morphologically similar to ''Aspicilia'', but differs from this genus in its mostly radiating thallus with either a wrinkled or lobate zone around the margins, in its generally smaller ascospores, and in the presence of the lichen product substictic acid. Species in the genus have a polar and arctic–alpine dist ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lichen Product
Lichen products, also known as lichen substances, are organic compounds produced by a lichen. Specifically, they are secondary metabolites. Lichen products are represented in several different chemical classes, including terpenoids, orcinol derivatives, chromones, xanthones, depsides, and depsidones. Over 800 lichen products of known chemical structure have been reported in the scientific literature, and most of these compound are exclusively found in lichens. Examples of lichen products include usnic acid (a dibenzofuran), atranorin (a depside), lichexanthone (a xanthone), salazinic acid (a depsidone), and isolichenan, an α-glucan. Many lichen products have biological activity, and research into these effects is ongoing. Lichen products accumulate on the outer walls of the fungal hyphae, and are quite stable. Crystal deposits can be visualised using scanning electron microscopy. For this reason, even very old herbarium specimens can be analysed. The amount of lichen products i ...
