Roccellinastrum
''Roccellinastrum'' is a genus of lichen-forming fungi in the family Pilocarpaceae. It has seven species. Taxonomy The genus was circumscribed in 1968 by German lichenologist Gerhard Follman, with '' Roccellinastrum spongoideum'' assigned as the type species. This byssoid lichen (appearing wispy, like teased wool) was found growing on cactus spines in the fog oases of western Chile. Follman classified the genus in the family Chrysothricaceae, as he emphasized the taxonomic importance of the byssoid thallus, and the similarity of the apothecium and ascus structure to those in that family. In 1983, Aino Henssen and colleagues emended the genus and placed it in the family Lecideaceae. ''Roccellinastrum'' is now classified in the family Pilocarpaceae. Description Species in genus ''Roccellinastrum'' are characterized by apothecia of diverse shape that lack a proper margin, and a developmental morphology corresponding to that of the order Lecanorales. They have small, a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Roccellinastrum Lagarostrobi
''Roccellinastrum lagarostrobi'' is a rare species of byssoid (wispy) lichen in the family Byssolomataceae. Found in Australia, it was formally described as a new species in 1990 by lichenologist Gintaras Kantvilas. The type specimen was collected from Pine Creek, north of Greystone bluff ( Tasmania) at an altitude of ; here, along the bank of a stream, at the edge of a rainforest, the lichen was found growing as an epiphyte on leafy twigs of the endemic conifer '' Lagarostrobos franklinii''. It has a white, cottony (byssoid) thallus that forms irregularly shaped tufts typically measuring 2–4 mm wide. The lichen produces the chemical protocetraric acid.

Byssoid Lichen
Lichens are composite organisms made up of multiple species: a fungal partner, one or more photosynthetic partners, and sometimes a basidiomycete yeast. They are regularly grouped by their external appearance – a characteristic known as their growth form. Lichenologists have described a dozen of these forms: areolate, byssoid, calicioid, cladoniform, crustose, filamentous, foliose, fruticose, gelatinous, leprose, placoidioid and squamulose. Of these, crustose, foliose and fruticose are the most commonly encountered. With the exception of calicioid lichens, growth forms are based on the appearance of the thallus, which is the vegetative (non-reproductive) part of the lichen. In most species, this form is determined by the lichen's fungal partner, though in a small number, it is instead the photobiont that determines the lichen's morphology. In some growth forms, the outermost layer of the thallus consists of tightly woven fungal . This layer, known as the cortex, may be found o ...

Pilocarpaceae
The Pilocarpaceae are a family of crustose lichens in the order Lecanorales. The species of this family have a cosmopolitan distribution and have been found in a variety of climatic regions. Pilocarpaceae was circumscribed by Alexander Zahlbruckner in Adolf Engler's influential 1905 work ''Die Natürlichen Pflanzenfamilien''. Description Pilocarpaceae species are crustose and have ascomata in the form of an brightly-coloured apothecium with a poorly-developed margin comprising loosely-intertwined hyphae. The ascospores are hyaline and often elongated with one or more septa. Genera Pilocarpaceae contains 32 genera and an estimated 445 species. The following list shows the genera, authority, year of publication, and number of species as of 2020 (unless a newer source is cited). *'' Aquacidia'' – 3 spp. *'' Badimiella'' – 1 sp. *'' Baflavia'' – 1 sp. *'' Bapalmuia'' – 22 spp. *'' Barubria'' – 2 spp. *'' Brasilicia'' – 6 spp. *'' Bryogomphus'' – 1 sp. *'' Bysso ...

Apothecia
An ascocarp, or ascoma (), is the fruiting body ( sporocarp) of an ascomycete phylum fungus. It consists of very tightly interwoven hyphae and millions of embedded asci, each of which typically contains four to eight ascospores. Ascocarps are most commonly bowl-shaped (apothecia) but may take on a spherical or flask-like form that has a pore opening to release spores (perithecia) or no opening (cleistothecia). Classification The ascocarp is classified according to its placement (in ways not fundamental to the basic taxonomy). It is called ''epigeous'' if it grows above ground, as with the morels, while underground ascocarps, such as truffles, are termed ''hypogeous''. The structure enclosing the hymenium is divided into the types described below (apothecium, cleistothecium, etc.) and this character ''is'' important for the taxonomic classification of the fungus. Apothecia can be relatively large and fleshy, whereas the others are microscopic—about the size of flecks of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Emendation (zoology)
In zoological nomenclature, emendations are alterations made to the spelling of taxon names. In bacteriological nomenclature, emendations are made to the circumscription of a taxon. In zoology The change must be consciously made along with justification for altering the spelling originally used by the taxon author while describing the species. Any other spelling changes are considered to be unjustified. Valid emendations include changes made to correct: * typographical errors in the original work describing the species; * errors in transliteration from non- Latin scripts; * names that included diacritic A diacritic (also diacritical mark, diacritical point, diacritical sign, or accent) is a glyph added to a letter or to a basic glyph. The term derives from the Ancient Greek (, "distinguishing"), from (, "to distinguish"). The word ''diacriti ...s or hyphens; * endings of species to match the gender of the generic name, particularly when the combination has been chang ...
