Asteristion
''Asteristion'' is a genus of lichen-forming fungi in the family Graphidaceae. It has seven species. Previously considered a synonym (taxonomy), synonym of either ''Phaeotrema'' or ''Thelotrema'', molecular phylogenetics, molecular evidence led to its resurrection as a distinct genus. ''Asteristion'' lichens are corticolous lichen, corticolous (bark-dwelling), featuring a continuous thallus with a loose to hardened and a containing calcium oxalate crystals. The , or fruiting bodies, are characterized by their large, often appearance and the presence of distinct . The secondary metabolism, secondary chemistry of these lichens includes major concentrations of stictic acid and minor to trace amounts of associated substances. Taxonomy ''Asteristion'' belongs to the tribe (biology), tribe Wirthiotremateae in the family Graphidaceae. This tribe, revised in 2017 to account for newly clarified phylogenetic relationships, contains the genera ''Wirthiotrema'', ''Austrotrema'', ''Asteri ...

Phaeotrema
''Phaeotrema'' is a genus of lichen-forming fungi in the family Graphidaceae. The genus was circumscribed in 1887 by Johannes Müller Argoviensis, with '' P. subfarinosum'' assigned as the type species. Species , Species Fungorum (in the Catalogue of Life The Catalogue of Life (CoL) is an online database that provides an index of known species of animals, plants, fungi, and microorganisms. It was created in 2001 as a partnership between the global Species 2000 and the American Integrated Taxono ...) accepts 20 species of ''Phaeotrema''. * '' Phaeotrema apertum'' * '' Phaeotrema chlorosporum'' * '' Phaeotrema disciforme'' * '' Phaeotrema discissum'' * '' Phaeotrema erumpens'' * '' Phaeotrema feeanum'' * '' Phaeotrema foraminulosum'' * '' Phaeotrema fuscescens'' * '' Phaeotrema glyphidellum'' * '' Phaeotrema leucastrum'' * '' Phaeotrema limae'' * '' Phaeotrema microcarpa'' * '' Phaeotrema pachysporum'' * '' Phaeotrema palmense'' * '' Phaeotrema phaeospermoi ...

Austrotrema
''Austrotrema'' is a genus of lichen-forming fungi in the family Graphidaceae. It is primarily found in the Australian-Southeast Asian region. The genus is characterized by small, pore-like with a double margin, faintly amyloid ascospores, and stictic acid chemistry. ''Austrotrema'' species grow on tree bark and have a continuous thallus with a that is –featuring densely packed, filamentous fungal hyphae that run parallel to the surface of the lichen, creating a compact and firm texture. The genus is closely related to ''Thelotrema'' and '' Leucodecton'', but can be distinguished from them based on molecular phylogenetic data, specific morphological traits, and its secondary chemistry. Currently, ''Austrotrema'' comprises three species. Taxonomy ''Austrotrema'' was circumscribed by lichenologists Ian Medeiros, Robert Lücking, and H. Thorsten Lumbsch in 2017. The genus was created to accommodate the three species of the ''Thelotrema bicinctulum'' species complex, which m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Graphidaceae
The Graphidaceae are a family of lichen-forming fungi in the order Graphidales. The family contains nearly a hundred genera and more than 2000 species. Although the family has a cosmopolitan distribution, most Graphidaceae species occur in tropical regions, and typically grow on bark. Taxonomy Graphidaceae was originally proposed by French botanist Barthélemy Charles Joseph Dumortier in 1822 (as "Graphineae"). '' Graphis'', '' Opegrapha'', and '' Arthonia'' were included in the new family. In 2002, the German lichenologist Bettina Staiger revised the Graphidaceae in a monograph, proposing a new classification of genera that was widely accepted until molecular phylogenetic studies led to a further reorganization of the family. Two subfamilies are recognized in the Graphidaceae: *Fissurinoideae *Graphidoideae Subfamily Redonographoideae, proposed by Lücking and colleagues in 2013, has since been promoted to familial status (as the monogeneric family Redonographaceae).

Wirthiotrema
''Wirthiotrema'' is a genus of lichen-forming fungi in the family Graphidaceae. The genus was circumscribed in 2010 by Eimy Rivas Plata, Klaus Kalb, Andreas Frisch, and H. Thorsten Lumbsch, with '' Wirthiotrema glaucopallens'' assigned as the type species. ''Wirthiotrema'' contains species that were formerly considered part of the ''Thelotrema glaucopallens'' species group. The genus name honours lichenologist Volkmar Wirth, "for his numerous outstanding contributions to lichenology". Characteristics of genus ''Wirthiotrema'' include thalli and apothecia that similar to those in genus '' Myriotrema'', in combination with a paraplectenchymatous excipulum (i.e., made of a fungal tissue with a cellular structure superficially like parenchyma of vascular plants), ascospores that are non-reactive with iodine-based stains, and the presence of stictic acid as a major secondary compound. Other compounds present in minor amounts include acetylconstictic acid, constictic acid, and co ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
