Allographa Ancelica
''Allographa'' is a genus of script lichens in the family Graphidaceae. It has nearly 200 species. Formally circumscribed in 1824 by François Fulgis Chevallier, ''Allographa'' was formerly included in '' Graphis'', but was upgraded to generic status in 2018 by lichenologists Klaus Kalb and Robert Lücking, who used molecular phylogenetics analysis to show this group of species to constitute a distinct lineage in the Graphidaceae. Description ''Allographa'' is characterised by ascomata (fruiting bodies), which are elongated and groove-like in shape. One of its defining features is the generally excipulum, which gives a dark appearance to the fruiting bodies, although some species formerly placed in ''Hemithecium'' with uncarbonised (blackened) are also included in this genus. ''Allographa'' typically displays robust and strongly prominent lirellae, often with a massive structure. The are hyaline (colourless) and usually large to very large in size, turning violet-blue when ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Diorygma
''Diorygma'' is a genus of lichen-forming fungi in the family Graphidaceae. The genus was circumscribed by Franz Gerhard Eschweiler in 1824. Species of the genus are widely distributed in tropical and subtropical regions of the world. These lichens form paint-like crusts on bark and rock that range from chalky white to light green, with elongated, pencil-like slits containing their spores that may flex and branch across the surface. The genus was established in 1824 for tropical script lichens with large, many-celled spores, but molecular studies in the 2000s and 2010s expanded it significantly by transferring species from other genera and revealing new diversity. Taxonomy The name ''Diorygma'' was coined by Franz Gerhard Eschweiler in 1824 for a group of neotropical script lichens in the family Graphidaceae that have large, many-celled () spores and a thin, naked hymenium. Elias Fries accepted the genus in 1825—likening it to what is now '' Arthonia''—but made no add ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Thalloloma
''Thalloloma'' is a genus of lichen-forming fungi in the family Graphidaceae. Established in 1853 by the Italian botanist Vittore Trevisan de Saint-Léon, the genus comprises 20 species distinguished by their narrow script-like slits immersed in a pale crusty surface, often with dark brown or occasionally crimson-dusted fruiting structures. Found throughout tropical regions from sea level to mountain forests above 3,000 metres, these bark-dwelling lichens are more tolerant of light and moisture variation than many related species, allowing them to colonise forest edges and moderately sun-exposed locations. Taxonomy The genus was circumscribed in 1853 by the Italian botanist Vittore Benedetto Antonio Trevisan de Saint-Léon. In his original description, Trevisan characterised ''Thalloloma'' by its immersed apothecia (fruiting bodies) that are either deformed, oblong, or -like in extension, with longitudinal slits that are surrounded by a prominent and lack a .

Sarcographa
''Sarcographa'' is a genus of lichen-forming fungi in the family Graphidaceae. Established in 1825 by the French botanist Antoine Laurent Apollinaire Fée, the genus contains 22 species that are recognised by their distinctive star-shaped colonies of radiating, script-like fruiting structures with black borders. These bark-dwelling lichens are found in humid tropical and warm temperate forests worldwide and serve as indicators of undisturbed woodland, as they quickly decline when forest canopy is opened or disturbed. Taxonomy The genus was circumscribed by the French botanist Antoine Laurent Apollinaire Fée in 1825. In his original description, Fée characterised the genus by its labyrinthine fruiting bodies () that are sunken into a fleshy support structure, with the disc initially covered by a powdery substance () and containing an elongated, branched nucleus with irregular striations. He initially described three species: '' S. cinchonarium'' (the type species) from ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Platythecium
''Platythecium'' is a genus of lichen-forming fungi in the family Graphidaceae. It comprises 25 species. Described in 2002 by the German lichenologist Bettina Staiger, these bark-dwelling lichens are found in humid, shaded forests across tropical and warm temperate regions worldwide. They are characterized by their flattened, plate-like fruiting structures with completely blackened walls and are sensitive to forest disturbance, making their presence an indicator of long-established woodland conditions. Taxonomy The genus was circumscribed in 2002 by the German lichenologist Bettina Staiger in her 2002 monographic treatment of the family Graphidaceae. '' Platythecium grammitis'' was assigned as the type species. Description ''Platythecium'' produces a smooth, pale grey-green to yellow-olive crust (thallus) that embeds directly in the bark and lacks a true . Its fruit bodies are short to elongate whose slate-black walls are completely ; the narrow slit is usually covered ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Platygramme
''Platygramme'' is a genus of lichen-forming fungi in the family Graphidaceae consisting of about 30 species. The genus was circumscribed by Antoine Laurent Apollinaire Fée in 1874. Several features characterise the genus ''Platygramme'': the brown ascospores, an hymenium, and fruiting bodies in which some of the tips of the are and form lamellae (plates).
