Catillaria flexuosa is a species of crustose lichen in the family Catillariaceae. It is found in the south of the Netherlands, where it grows on the bark of roadside ash trees.
The lichen was formally described as a new species in 2021 by lichenologists Pieter van den Boom and Pablo Alvarado. The type specimen was collected south of the village of Zijtaart, where it was found growing on a medium-sized ash tree along the side of a road. [1]
The newly described lichen is closely related to Catillaria chalybeia , the type species of genus Catillaria . Several morphological features of the thallus distinguish Catillaria flexuosa–it is dark green and relatively thick (up to 0.4 mm), continuous to weakly rimose, areolate, with knobby granules, and it can sometimes become somewhat squamulose. The apothecia of C. flexuosa are abundant on the thallus. They are typically flat with a small but conspicuous proper margin, and often have a flexuous form–bending in alternate directions. It is for this last feature that the species is given its specific epithet. No secondary chemicals were detected in the lichen using thin layer chromatography. [1]
Catillaria flexuosa is a corticolous lichen, and grows on the bark of Fraxinus excelsior trees. Its limited geographical distribution includes five locations in the east of the province of Noord-Brabant. [1]
Sagenidiopsis isidiata is a species of corticolous (bark-dwelling) byssoid lichen in the family Arthoniaceae. Found in tropical montane rainforests throughout Central America, South America, and the Antilles, it was described as new to science in 2011. The lichen is characterised by its cream-coloured to greyish thallus and numerous pseudoisidia, which are small, cylindrical outgrowths on its surface.
Coccocarpia delicatula is a species of foliicolous (leaf-dwelling) foliose lichen in the family Coccocarpiaceae. Known only from the Galápagos Islands and Réunion, it was described as new to science in 2011. Characterised by its rounded, foliose thallus and unique cylindrical isidia, this lichen is similar in appearance to Coccocarpia domingensis but has distinct differences in isidia shape and arrangement. Found on the bark and wood of dead twigs, Coccocarpia delicatula thrives in sunny, wind- and rain-exposed environments.
Punctelia ulophylla is a species of foliose lichen in the family Parmeliaceae. It is found in Europe, where it grows on the bark of a variety of trees.
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.
Solenopsora is a genus of lichen-forming fungi in the family Catillariaceae. It has 15 species, with a mostly Northern Hemisphere distribution.
Lepraria incana is a species of dust lichen in the family Stereocaulaceae. First described scientifically by Johann Jacob Dillenius in 1741, and then formally by Carl Linnaeus in 1753, it is the type species of the genus Lepraria. The thallus of this species is green to greyish-green, and powdery – as if made of tiny granules. These granules are soredia, which are asexual reproductive structures. Like most members of genus Lepraria, the lichen has few distinguishing features, lacking both a medulla and sexual reproductive structures (apothecia). Chemically, the lichen is characterised by the presence of the secondary chemicals known as divaricatic acid and zeorin.
Acanthothecis salazinica is a species of script lichen in the family Graphidaceae. Found in Panama, it was described as a new species in 2013 by Pieter van den Boom and Harrie J. Sipman. The type specimen was collected near Paraíso, Panamá Province, close to the botanical garden in the Summit Park. Here it was growing on the bark of a cultivated Parmentiera cereifera tree. The lichen contains the secondary chemical salazinic acid, for which it is named. Acanthothecis subclavulifera is quite similar in morphology, but it contains protocetraric acid rather than salazinic acid and it has a different ascospore structure.
Zwackhiomyces parmotrematis is a species of lichenicolous fungus in the family Xanthopyreniaceae. Found in Suriname, it was formally described as a new species in 2018 by Dutch lichenologist Pieter van den Boom. The type was collected west of Groningen in an abandoned Citrus orchard. Here it was found growing on the thallus of Parmotrema praesorediosum. The fungus does not cause visible damage to its host, such as discolouration or the formation of galls; rather, it produces tiny black, spherical perithecia that are immersed in the host thallus. The specific epithet parmotrematis refers to the genus of its host lichen.
Amandinea myrticola is a species of corticolous (bark-dwelling), crustose lichen in the family Caliciaceae. Found in Portugal, it was formally described as a new species in 2011 by Mireia Giralt, Pieter van den Boom, and John Elix. The type specimen was collected by the second author from the south side of Barragem de Odivelas (Alentejo); the lichen has also been recorded from another locality in Alentejo. It grows on the smooth bark of Myrtus communis and Pinus twigs. The thallus of the lichen is a smooth to lightly wrinkled grey crust, lacking a prothallus. Amandinea myrticola produces ascospores of the Physconia-type, characterised by a thick septum and median wall thickenings. They are ellipsoid in shape, and typically measure 11–13.5 by 5–6 μm. The lichen does not make any secondary compounds that are detectable with standard chromatographic techniques, and all reactions to standard chemical spot tests are negative.
Micarea pauli is a species of corticolous and lignicolous, crustose lichen in the family Pilocarpaceae. It is only known to occur in Poland's Białowieża Forest.
Astrothelium pseudoferrugineum is a species of corticolous (bark-dwelling), crustose lichen in the family Trypetheliaceae. Found in Indonesia, it was formally described as a new species in 2016 by Dutch lichenologist André Aptroot. The type specimen was collected in 1937 by Pieter Groenhart on Jombang (Java); there, it was found in a disturbed rainforest growing on smooth tree bark. The lichen has a smooth and somewhat shiny to glossy, bright orange thallus with a cortex but without a prothallus. The orange crust is about 0.1 mm thick and covers areas of up to 3 cm (1.2 in) in diameter. The use of thin-layer chromatography shows the lichen contains an orange anthraquinone, possibly parietin. The main characteristics of the lichen that distinguish it from others in Astrothelium are its immersed to erumpent, whitish pseudostromata. It is named for its similarity to Astrothelium ferrugineum, from which it differs in its glossier thallus and larger ascospores.
Alyxoria viridipruinosa is a species of corticolous (bark-dwelling) and lignicolous (wood-dwelling) lichen in the family Lecanographaceae. It is found in Europe, where it grows on hardwood trees.
Abrothallus boomii is a species of lichenicolous fungus in the family Abrothallaceae. Found in Portugal, it was formally described as a new species in 2015 by Ave Suija and Sergio Pérez-Ortega. The type specimen was collected north of Ervas Tenras in a pine-oak forest along a vineyard, where it was found growing on the thallus of a Nephroma lichen. It is only known to occur at the type locality. The species epithet honours Dutch lichenologist Pieter van den Boom, "author of a long list of research articles and indefatigable collector of lichens and lichenicolous fungi".
Vigneronia spieri is a species of corticolous (bark-dwelling), crustose lichen in the family Roccellaceae. It is found in the Galápagos Islands, mainland Ecuador and the Antilles (Curaçao).
Physcidia striata is a species of corticolous (bark-dwelling), microfoliose lichen in the family Ramalinaceae. Found in South America, it was formally described as a new species in 2014 by lichenologists André Aptroot, Marcela Cáceres, and Einar Timdal. The type specimen was collected by the first two authors from the Estação Ecológica de Cuniã (Rondônia), where it was found growing on the smooth bark of a tree in a primary rainforest. It also occurs in Peru. The thallus of the lichen is a loose mat of squamules (scales) without a hypothallus. Its lobes are smooth, flat, branched, and greyish-green, measuring 2–7 mm long by 0.5–1.5 mm wide. The species epithet striata refers to the faint longitudinal striations that are present on the lobe undersides. Isidia occur on the thallus surface; they are the same colour as the thallus, with dimensions of 0.3–0.7 mm long by 0.1–0.2 mm wide. When they are abraded, it reveals the whitish colour of the underlying medulla. The lichen contains divaricatic acid, a lichen product that is revealed with the use of thin-layer chromatography.
Catillaria gilbertii is a rare species of saxicolous (rock-dwelling), crustose lichen in the family Catillariaceae. It is found in the Central Highlands of Scotland.
Lecanora compallens is a species of corticolous (bark-dwelling) crustose lichen in the family Lecanoraceae. Found in Asia and Europe, it was formally described as a new species in 1999 by lichenologists Kok van Herk and André Aptroot. The type specimen was collected by the first author from Drouwenerveen (Drenthe), where it was found growing on the bark of Quercus robur. The species epithet compallens is derived from the Latin com and (ex)pallens, alluding to the typical occurrence of the morphologically similar Lecanora expallens at the same location.
Lecania juniperi is a rare species of corticolous (bark-dwelling), crustose lichen in the family Ramalinaceae. Discovered on Juniperus phoenicea shrubs in the coastal region of Portugal, it was formally described as a new species in 2012. Despite its resemblance to Lecania cyrtella, L. juniperi stands out due to its warted and sorediate thallus, larger apothecia, and distinct ascospores.
Lichenopeltella heppiae is a rare species of lichenicolous (lichen-dwelling) fungus in the family Lichenopeltella. It grows on the thallus and apothecia of Heppia despreauxii.
Waynea algarvensis is a rare species of corticolous (bark-dwelling) squamulose lichen in the family Ramalinaceae. Native to the Algarve province in Portugal, it was formally described as a new species in 2012. Closely related to Waynea cretica, this lichen is characterized by its minute thallus parts and fusiform (spindle-shaped) ascospores. Found primarily on olive trees, this lichen forms part of understudied epiphytic communities in the region.
