Catillaria gilbertii is a rare species of saxicolous (rock-dwelling), crustose lichen in the family Catillariaceae. [1] It is found in the Central Highlands of Scotland.
The lichen was formally described as a new species in 1996 by lichenologists Alan Fryday and Brian Coppins. The type specimen was collected by the first author from the Ben Lawers National Nature Reserve (Perthshire) at an altitude of 890 m (2,920 ft); there, it was found growing on an east-facing mica-schist rock face. The species epithet was named to honour British lichenologist Oliver Gilbert "for his pioneering work on the montane lichen vegetation of the British Isles". [2] They noted that the naming of this species, which produces twice the usual number of ascospores in its asci, was "particularly appropriate given the pre-disposition of the Gilbert family for producing twice the usual number of offspring at a time; Dr Gilbert himself is a twin and he also has twin daughters". [2]
The lichen has dark-brown to dark grey thallus that is bluish-grey when wet. It is areolate (with individual areoles measuring about 0.15–0.27 mm in diameter), cracked, and effuse . Its apothecia are dark brown to black with a lecideine form and a diameter between 0.3–0.7 mm; there is a slightly raised proper margin (width of 0.04–0.1 mm) surrounding the flat or slightly convex disc . Its ascospores are hyaline with an oblong to ellipsoid shape and a single septum, and measure 10–12 by 2.5–3 μm. The spores typically number 16 per ascus, which itself is of the Catillaria -type—with a uniformly amyloid dome at the apex. Immersed in the thallus surface are conidiomata in the form of pycnidia ; they are 60–80 μm in diameter and produce conidia that are ellipsoid to ovoid with dimensions of 2.5–3 by 0.8–1.4 μm. [2]
All parts of Catillaria gilbertii do not react with any of the standard chemical spot tests used to test for the presence of lichen products. [2]
Catillaria gilbertii is only known to occur in the mica-schist mountains of the Scottish Central Highlands. In addition to the type locality, it has also been recorded in Glen Esk in Angus. [2] It is one of relatively few endemic lichens known in Scotland, and one of even fewer that inhabit the hyper-oceanic mountain habitat, above the tree line. [3] Two similar species that occur in the same habitat are Catillaria chlybeia and Halecania rhypodiza . [2]
Ameliella is a genus of lichenized fungi in the family Lecanoraceae. Described in 2008, the genus contains two species, A. andreaeicola and A. grisea, that were collected from high elevations in the Scottish Highlands. The two species have also been found in single instances in British Columbia and Northern Norway. The generic name is derived from the Greek ameleo, meaning "neglected" or "overlooked"; it was originally intended to be Amelia, which is also the first name of the daughter of one of the authors, but this name had previously been used for another genus and was therefore ineligible for use according to the rules of mycological nomenclature. Ameliella appears to have some similarity with the lichen genus Miriquidica.
Catillaria is a genus of crustose lichens in the family Catillariaceae. The genus was circumscribed by Italian lichenologist Abramo Bartolommeo Massalongo in 1852. It is the type genus of Catillariaceae, which was circumscribed by Austrian lichenologist Josef Hafellner in 1984.
Punctelia jujensis is a species of foliose lichen in the family Parmeliaceae. It is found in Argentina and Brazil.
Xenonectriella nephromatis is a species of lichenicolous fungus in the family Nectriaceae. Found in Alaska, it was described as a species new to science in 2020 by Sergio Pérez-Ortega. The type specimen was discovered in the Hoonah–Angoon Census Area in Glacier Bay National Park, where it was growing on a Nephroma lichen. The specific epithet alludes to this host lichen.
Halecania athallina is a species of lichen in the family Leprocaulaceae. Found in Alaska, it was described as new to science in 2020 by British lichenologist Alan Fryday. The type specimen was discovered in Hoonah-Angoon Census Area in Glacier Bay National Park. There it was found growing on argillite rock on an alpine heath with rock outcrops.
Porpidia seakensis is a species of crustose lichen in the family Lecideaceae. It is an endolithic species, meaning it grows inside the rocks, between the grains. Found only in Alaska, it was formally described as a new species in 2020 by British lichenologist Alan Fryday. The type specimen was collected in the Hoonah-Angoon Census Area, in Glacier Bay National Park. Here it was discovered growing on granitic rock in a woodland. The lichen is only known from this area, although it is locally common. Its preferred habitat is siliceous rocks and boulders in wooded areas that are open and well lit. The specific epithet seakensis uses the letters "seak" to refer to a standard abbreviation for southeast Alaska.
Fuscopannaria dillmaniae is a species of lichen in the family Pannariaceae. Found in Alaska, it was described as a new species in 2020 by lichenologist Toby Spribille.
Ocellularia brunneospora is a species of corticolous (bark-dwelling) lichen in the family Graphidaceae. Found in Thailand, it was formally described as a new species in 2002 by lichenologists Natsurang Homchantara and Brian J. Coppins. The type specimen was collected in the Namtok Phlio National Park ; here, in a moist evergreen forest at an elevation of 100 m (330 ft), the lichen was found growing on the bark of Anisoptera costata. Ocellularia brunneospora is only known to occur at the type locality.
Ocellularia neoperforata is a rare species of corticolous (bark-dwelling) lichen in the family Graphidaceae. Found in Malaysia, it was formally described as a new species in 2002 by lichenologists Natsurang Homchantara and Brian J. Coppins. The type specimen was collected by the second author from Gunung Mulu National Park (Sarawak) at an elevation of about 100 m (330 ft); here, it was found in a heath forest growing on a young tree. It is only known from the type collection at the type locality. The lichen has a shiny and smooth, greenish-grey thallus with a dense cortex and a white medulla. Its ascospores are trans-septate, narrowly ellipsoid, and measure 11–15 μm long. It contains fumarprotocetraric acid, a secondary compound. Ocellularia perforata is a lookalike species after which O. neoperforata is named. In contrast to the latter lichen, it has larger ascospores, less emergent apothecia, and contains protocetraric acid.
Ocellularia pluriporoides is a species of corticolous (bark-dwelling) lichen in the family Graphidaceae. Found in Northern Thailand, it was formally described as a new species in 2002 by lichenologists Natsurang Homchantara and Brian J. Coppins. The type specimen was collected in Doi Suthep National Park at an elevation of 1,600 m (5,200 ft); here, in an oak/chestnut forest, it was found growing on the trunk of Vaccinium sprengelii.
Leucodecton coppinsii is a species of corticolous (bark-dwelling) lichen in the family Graphidaceae. It is found in lowland forests of Sarawak, Malaysia.
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.
Pyrenula luteopruinosa is a species of corticolous (bark-dwelling), crustose lichen in the family Pyrenulaceae. It has a neotropical distribution, occurring in Panama, Costa Rica, Puerto Rico, and Hawaii.
Phylloblastia inexpectata is a species of foliicolous (leaf-dwelling) lichen in the family Verrucariaceae. Found in Europe, it was formally described by lichenologists Emmanuël Sérusiaux, Brian John Coppins, and Robert Lücking. The type specimen was collected by the second author in Dunskey Glen Woods, where it was found growing on the leaves of a Prunus laurocerasus tree growing near a stream. It has also been collected in England, southern Italy, Madeira, and Spain.
Verrucaria simplex is a species of saxicolous (rock-dwelling), crustose lichen in the family Verrucariaceae. Found in Europe and Asia, it was described as new to science in 1988 by lichenologist Patrick McCarthy. The type specimen was collected by Brian Coppins from Morpeth, Northumberland; there, it was found growing on a fragment of mortar-cement lying on the floor of a woodland. The lichen was later reported from the Czech Republic, and Korea.
Verrucaria nodosa is a species of saxicolous (rock-dwelling), crustose lichen in the family Verrucariaceae. Found in freshwater habitats in Wales, it was formally described as a new species in 2013 by lichenologist Alan Orange. The type specimen was collected by the author north-west of Llanuwchllyn, Merioneth, where it was found growing on an unshaded rock in a stream. The lichen has a grey-green to dark brown thallus with an uneven surface crust. Its ascomata are in the form of somewhat convex to hemispherical perithecia measuring 220–460 μm in diameter, with an inconspicuous or tiny ostiole. Ascospores are ellipsoid and colourless, lack any septa, and typically measure 20.5–22.2–24.0 by 90–97–105 μm. The species is known only from a few streams in Wales, where it grows on shaded or lightly shaded rocks. Associated lichen species include Ionaspis lacustris, Rhizocarpon lavatum, Porpidia hydrophila, Sporodictyon cruentum, and Trapelia coarctata, as well as the mosses Racomitrium aciculare and Scapania undulata.
Oliver Gilbert was an urban ecologist and lichenologist. He was a reader in landscape ecology at Sheffield University. He was one of the early users of lichens as indicators of air pollution, and also studied the ecology and diversity of wildlife in urban areas.
Asterothyrium vezdae is a species of foliicolous (leaf-dwelling) lichen in the family Gomphillaceae. It is found in Bolivia, where it grows on the leaves of vascular plants in the Amazon rainforest. The lichen is distinguished from its closest relative, Asterothyrium octomerum, by the larger number of septa in its ascospores, and its and black apothecia.
Gyalideopsis aptrootii is a species of corticolous lichen in the family Gomphillaceae. Found in southern Brazil, it was described as a new species in 2018. Defining features of this lichen include the unique crescent-shaped structure of its hyphophores, the single-spored asci, and the relatively small size of the ascospores.
Verrucaria viridula is a common and widely distributed species of saxicolous (rock-dwelling), crustose lichen in the family Verrucariaceae. Although it is a somewhat morphologically variable species, two persistent distinguishing characteristics are its relatively large perithecia, which are often curved into a beak, and its large ascospores.
