Xalocoa
''Xalocoa'' is a single-species fungal genus in the family Graphidaceae. The genus was circumscribed in 2013 by lichenologists Ekaphan Kraichak, Robert Lücking, and H. Thorsten Lumbsch. It contains ''Xalocoa ocellata'', a corticolous (bark-dwelling), crustose lichen that was originally described by Elias Magnus Fries in 1831 (as ''Parmelia ocellata''). ''Xalocoa'' belongs to the subfamily Graphidoidae, and tribe Thelotremateae in the Graphidaceae. The genus is characterized by its greyish-white thallus covered by an layer, large apothecioid ascomata with exposed and thick, entire thalline margins, as well as a thin, reduced, that lacks lateral . The genus features a non- hymenium, pale brown, non-amyloid ascospores, bacilliform , and contains the norstictic acid . The genus name ''Xalocoa'' originates from the Catalan term , which signifies the sirocco, a warm wind that comes from the Sahara and affects Mediterranean regions. The species epithet pays tribute to Xavier Ll ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Graphidaceae
The Graphidaceae are a family of lichens in the order Ostropales. Distribution and ecology The vast majority of Graphidaceae species are restricted to the tropics. Most Graphidaceae species are epiphytic (i.e. they grow only on plants). Genera A recent (2020) estimates places 31 genera and about 990 species in Graphidaceae. The following list indicates the genus name, the taxonomic authority, year of publication, and the number of species: *''Acanthothecis'' – 5 spp. *''Acanthotrema'' – 1 sp. *''Aggregatorygma'' – 1 sp. *''Allographa'' – 183 spp. *''Amazonotrema'' – 1 sp. *'' Ampliotrema'' – 1 sp. *'' Anomalographis'' – 2 spp. *''Anomomorpha'' – 8 spp. *''Astrochapsa'' – 29 spp. *'' Austrotrema'' – 3 spp. *'' Borinquenotrema'' – 1 sp. *'' Byssotrema'' – 1 sp. *''Carbacanthographis'' – 22 spp. *''Chapsa'' – 51 spp. *''Chroodiscus'' – 17 spp. *'' Clandestinotrema'' – 17 spp. *'' Compositrema'' – 4 spp. *'' Corticorygma'' – 1 ...

Robert Lücking
Robert Lücking (born 1964) is a German lichenologist. He is a leading expert on foliicolous lichens–lichens that live on leaves. Life and career Born in Ulm in 1964, Lücking earned both his master's (1990) and PhD degree (1994) at the University of Ulm. Both degrees concerned the taxonomy, ecology, and biodiversity of foliicolous lichens. His graduate supervisor was mycologist and bryologist Sieghard Winkler, who had previously studied epiphyllous (upper leaf-dwelling) fungi in El Salvador and Colombia. In 1996 Lücking was awarded the Mason E. Hale award for an "outstanding doctoral thesis presented by a candidate on a lichenological theme". His thesis was titled ''Foliikole Flechten und ihre Mikrohabitatpraferenzen in einem tropischen Regenwald in Costa Rica'' ("Foliicolous lichens and their microhabitat preferences in a tropical rainforest in Costa Rica"). In this work, Lücking recorded 177 foliicolous lichen species from the shrub layer in a Costa Rican tropical forest. L ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tribe (biology)
In biology, a tribe is a taxonomic rank above genus, but below family (biology), family and subfamily. It is sometimes subdivided into subtribes. By convention, all taxonomic ranks from genus upwards are capitalized, including both tribe and subtribe. In zoology, the standard ending for the name of a zoological tribe is "-ini". Examples include the tribes Goat-antelope#Tribe Caprini, Caprini (goat-antelopes), Hominini (hominins), Bombini (bumblebees), and Thunnini (tunas). The tribe Hominini is divided into subtribes by some scientists; subtribe Hominina then comprises "humans". The standard ending for the name of a zoological subtribe is "-ina". In botany, the standard ending for the name of a botanical tribe is "-eae". Examples include the tribes Acalypheae and Scilloideae#Hyacintheae, Hyacintheae. The tribe Hyacintheae is divided into subtribes, including the subtribe Massoniinae. The standard ending for the name of a botanical subtribe is "-inae". In bacteriology, the form ...

Lichen Genera
A lichen ( , ) is a composite organism that arises from algae or cyanobacteria living among filaments of multiple fungi species in a mutualistic relationship.Introduction to Lichens – An Alliance between Kingdoms . University of California Museum of Paleontology. Lichens have properties different from those of their component organisms. They come in many colors, sizes, and forms and are sometimes plant-like, but are not plants. They may have tiny, leafless branches ( fruticose); flat leaf-like structures ( foliose); grow crust ...

Species Fungorum
''Index Fungorum'' is an international project to index all formal names ( scientific names) in the fungus kingdom. the project is based at the Royal Botanic Gardens, Kew, one of three partners along with Landcare Research and the Institute of Microbiology, Chinese Academy of Sciences. It is somewhat comparable to the International Plant Names Index (IPNI), in which the Royal Botanic Gardens is also involved. A difference is that where IPNI does not indicate correct names, the ''Index Fungorum'' does indicate the status of a name. In the returns from the search page a currently correct name is indicated in green, while others are in blue (a few, aberrant usages of names are indicated in red). All names are linked to pages giving the correct name, with lists of synonyms. ''Index Fungorum'' is one of three nomenclatural repositories recognized by the Nomenclature Committee for Fungi; the others are ''MycoBank'' and '' Fungal Names''. Current names in ''Index Fungorum'' (''Sp ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Diploschistes
''Diploschistes'' (crater lichen) is a genus of crustose lichens with a thick, cracked (areolate) body (thallus) with worldwide distribution.Field Guide to California Lichens, Stephen Sharnoff, Yale University Press, 2014, The fruiting part (apothecia) are immersed in the thick thallus so as to have the appearance of being small "craters". It is in the family Thelotremataceae. The widespread genus contains about 43 species. Johannes Musæus Norman described the genus in 1853.

Botanical Name
A botanical name is a formal scientific name conforming to the ''International Code of Nomenclature for algae, fungi, and plants'' (ICN) and, if it concerns a plant cultigen, the additional cultivar or Group epithets must conform to the '' International Code of Nomenclature for Cultivated Plants'' (ICNCP). The code of nomenclature covers "all organisms traditionally treated as algae, fungi, or plants, whether fossil or non-fossil, including blue-green algae ( Cyanobacteria), chytrids, oomycetes, slime moulds and photosynthetic protists with their taxonomically related non-photosynthetic groups (but excluding Microsporidia)." The purpose of a formal name is to have a single name that is accepted and used worldwide for a particular plant or plant group. For example, the botanical name '' Bellis perennis'' denotes a plant species which is native to most of the countries of Europe and the Middle East, where it has accumulated various names in many languages. Later, the plant w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mediterranean Region
In biogeography, the Mediterranean Basin (; also known as the Mediterranean Region or sometimes Mediterranea) is the region of lands around the Mediterranean Sea that have mostly a Mediterranean climate, with mild to cool, rainy winters and warm to hot, dry summers, which supports characteristic Mediterranean forests, woodlands, and scrub vegetation. Geography The Mediterranean Basin covers portions of three continents: Europe, Africa, and Asia. It is distinct from the drainage basin, which extends much further south and north due to major rivers ending in the Mediterranean Sea, such as the Nile and Rhône. Conversely, the Mediterranean Basin includes regions not in the drainage basin. It has a varied and contrasting topography. The Mediterranean Region offers an ever-changing landscape of high mountains, rocky shores, impenetrable scrub, semi-arid steppes, coastal wetlands, sandy beaches and a myriad islands of various shapes and sizes dotted amidst the clear blue sea. ...

Catalan Language
Catalan (; autonym: , ), known in the Valencian Community and Carche as '' Valencian'' ( autonym: ), is a Western Romance language. It is the official language of Andorra, and an official language of three autonomous communities in eastern Spain: Catalonia, the Valencian Community, and the Balearic Islands. It also has semi-official status in the Italian comune of Alghero. It is also spoken in the Pyrénées-Orientales department of France and in two further areas in eastern Spain: the eastern strip of Aragon and the Carche area in the Region of Murcia. The Catalan-speaking territories are often called the or "Catalan Countries". The language evolved from Vulgar Latin in the Middle Ages around the eastern Pyrenees. Nineteenth-century Spain saw a Catalan literary revival, culminating in the early 1900s. Etymology and pronunciation The word ''Catalan'' is derived from the territorial name of Catalonia, itself of disputed etymology. The main theory suggests ...
