Buellia saxorum is a species of crustose lichen belonging to the family Caliciaceae. [1] It is found in Europe. [1]
Buellia is a genus of mostly lichen-forming fungi in the family Caliciaceae. The fungi are usually part of a crustose lichen. In this case, the lichen species is given the same name as the fungus. But members may also grow as parasites on lichens (lichenicolous). The algae in the lichen is always a member of the genus Trebouxia.
Catolechia is a genus of lichen-forming fungi in the family Rhizocarpaceae. It is a monotypic genus, containing the single species Catolechia wahlenbergii. The genus was circumscribed by German botanist Julius von Flotow in 1850. He did not assign a type species for the genus; Catolechia pulchellaA.Massal. (1852) was designated as the type by Gustav Wilhelm Körber in 1855. This species is synonymous with Catolechia wahlenbergii.
The Caliciaceae are a family of mostly lichen-forming fungi belonging to the class Lecanoromycetes in the division Ascomycota. Although the family has had its classification changed several times throughout its taxonomic history, the use of modern molecular phylogenetic methods have helped to establish its current placement in the order Caliciales. Caliciaceae contains 39 genera and about 670 species. The largest genus is Buellia, with around 300 species; there are more than a dozen genera that contain only a single species.
Buellia dispersa is a dull white to beige or dark brown crustose areolate lichen that grows on non-calcareous rock, such as basalt, granite and gneiss, in arid to semi-arid areas of northern Africa, Europe, and southwestern North America. The areolas are distinct, becoming subsquamulose when separated and collecting in irregular patches, otherwise they form rosettes with lobed margins. There is no prothallus. It commonly occurs in the Mojave Desert, Channel Islands, and Santa Monica Mountains, also in the Cuyamaca Mountains, Santa Ana Mountains, and San Jacinto Mountains. It is among the most common lichen species in the Sonoran Desert.
Buellia spuria, the disc lichen, is a white to light ashy gray crustose areolate lichen that grows on rocks (epilithic) in montane habitats. It has a black edge from the conspicuous, more or less continuous prothallus, which can also be seen in the cracks between the areolas forming a hypothallus, and in sharp contrast with the whitish or ashy colored areolas. It prefers mafic (siliceous) rock substrates. In Joshua Tree National Park is can be seen on vertical granite and gneiss faces in washes. It is common worldwide in the Northern Hemisphere. It is very common in the Sonoran Desert from southern California to Arizona, Baja California, and Sonora, Chihuahua, and Sinaloa, Mexico.
Buellia abstracta is a crustose lichen.
Ashdown Park is a 9.3-hectare (23-acre) biological Site of Special Scientific Interest (SSSI) south of Ashbury in Oxfordshire. The SSSI is part of the park of Ashdown House.
Buellia asterella, commonly referred to as the starry breck lichen, is a rare, black and white lichen in the family Caliciaceae. Once found all across the central European grasslands, it was described as new to science in 1974. Today, it is classified by the IUCN Red List as Critically Endangered and only found in select regions in Norway and Germany.
Park Farm Down or Parkfarm Down is a 3.3-hectare (8.2-acre) biological Site of Special Scientific Interest north-west of Lambourn in Berkshire. It is in the North Wessex Downs, which is an Area of Outstanding Natural Beauty.
'Eristalis saxorum, the Blue-polished Drone Fly, is an uncommon species of syrphid fly found along the Eastern United States. Hoverflies get their names from the ability to remain nearly motionless while in flight. The adults are also known as flower flies for they are commonly found around and on flowers, from which they get both energy-giving nectar and protein-rich pollen. The larvae are aquatic filter-feeders of the rat-tailed type. The larvae of this species have not been identified. Little is known about this uncommon species which flies from mid-March to late October.
Streptocarpus saxorum, called the false African violet, is a species of flowering plant in the genus Streptocarpus, subgenus Streptocarpella, native to Kenya and Tanzania. It is an evergreen perennial that often bears flowers nearly year-round. Its "compact" variety has gained the Royal Horticultural Society's Award of Garden Merit as a houseplant.
Buellia gypsyensis is a species of crustose lichen in the family Caliciaceae. Found in the Falkland Islands, it was described as a new species in 2019 by British lichenologist Alan Fryday. The type was collected from Gypsy Cove near Port Stanley in East Falkland, where it was found growing on a north-facing rock; it is named for its type locality. The main distinguishing characteristics of the lichen are its filiform (threadlike) conidia and the presence of 5-O-methylhiascic acid as the major secondary chemical in the thallus.
Buellia subeffigurata is a species of crustose lichen in the family Caliciaceae. Found in South Africa, it was formally described as a new species in 2021 by John Alan Elix, Helmut Mayrhofer, and Wolfgang Wetschnig. The type specimen was collected in the Knersvlakte, at an altitude of 150 m (490 ft). Here the saxicolous lichen was found growing on quartziferous rock. The species epithet refers to its subeffigurate marginal lobes. The results of standard chemical spot tests are: thallus K+ (yellow), P+ (yellow-orange), and C−. Buellia subeffigurata contains thiophanic acid as a major secondary chemical, and isoarthothelin and atranorin as minor compounds.
Buellia georgei is a species of lichen in the family Caliciaceae. Found in Australia, it was formally described as a new species in 2001 by lichenologists Ulrike Trinkaus, Helmut Mayrhofer, and John Elix. The type specimen was collected in Yanchep National Park ; here it was found growing on soft limestone. It has also been recorded from South Australia, New South Wales, and the Australian Capital Territory; preferred habitats are calcareous outcrops, on thin soil over limestone, or rarely on calcareous soil. The lichen produces some secondary compounds: arthothelin as a major metabolite, and minor amounts of 4,5-dichloronorlichexanthone and thiophanic acid. The specific epithet honours Western Australian botanist Alex George.
Buellia schaereri is a species of lichen in the family Caliciaceae. It was formally described as a new species in 1849 by Italian botanist Giuseppe De Notaris. The botanical name honours Swiss pastor and lichenologist Ludwig Schaerer. It is a widely distributed lichen, occurring in Africa, Asia, Northern and Central Europe, Macaronesia, Central America, and North America. It grows on the bark and wood of trees, especially conifers and oak.
Buellia epifimbriata is a species of lichenicolous (lichen-eating) crustose lichen in the family Caliciaceae. It is only known to occur on Antiparos and Kos, two Greek islands in the southern Aegean Sea.
Ciposia is a single-species fungal genus in the family Caliciaceae. Circumscribed by Bernhard Marbach in 2000, it contains the species Ciposia wheeleri, a corticolous (bark-dwelling) and crustose lichen. This species was originally classified in genus Buellia by Richard Harris in 1988.
Buellia erubescens, the common button lichen, is a species of lichen in the genus Buellia. It is found commonly on the bark and occasionally on the wood of Quercus, Pinus, Juniperus, or other species of trees with bark that has generally low pH. It is common between 600 and 3,000 m elevation, and is common in submontane to subalpine forests.
