Cyphellostereum is a genus of basidiolichens. Species produce white, somewhat cup-shaped fruit bodies on a thin film of green on soil which is the thallus. All Cyphellostereum species have nonamyloid spores and tissues, lack clamp connections, and also lack hymenial cystidia.
Acantholichen is a fungal genus in the family Hygrophoraceae. The genus was circumscribed by Norwegian lichenologist Per Magnus Jørgensen to contain the type, and at that time, only species, the basidiolichen Acantholichen pannarioides, discovered originally in Costa Rica in 1998. This species has a bluish, gelatinous thallus, and a fine, white powdery bloom covering the hairy upper surface; this surface is said to resemble "an unshaven chin". Five additional species, all basidiolichens, were added to the genus in 2016 following an in-depth analysis of specimens collected from the Galápagos, Costa Rica, Brazil and Colombia.
Dictyonema is a genus of mainly tropical basidiolichens in the family Hygrophoraceae.
Dictyonema hernandezii is a species of basidiolichen in the family Hygrophoraceae. Found in montane rainforests of Costa Rica and in Colombia, it was described as new to science in 2011. The specific epithet hernandezii honours Venezuelan lichenologist Jesús Hernández.
Cora hirsuta is a species of basidiolichen in the family Hygrophoraceae. Found in the páramo region near Bogotá at over 3,000 m (9,800 ft) elevation, it was described as new to science in 2011. The lichen, characterised by its distinctively hairy upper surface and smaller lobes, thrives in a variety of habitats, including soil, bryophytes, and as epiphytes on trees.
Cora is a large genus of basidiolichens in the family Hygrophoraceae. Modern molecular phylogenetics research has revealed a rich biodiversity in this largely tropical genus.
Emmanuël Sérusiaux is a Belgian lichenologist. His career, spanning more than four decades, has combined both lichenology research and political aspects of nature conservation. He spent several periods working as a researcher at the National Fund for Scientific Research and the University of Liège, the latter in which he accepted a faculty position as professor and head of the Plant Taxonomy and Conservation Biology unit. Sérusiaux also served for three non-consecutive appointments as Deputy Chief of Staff in the Government of Wallonia. He retired from both his academic and political positions in 2019.
Cora santacruzensis is a species of basidiolichen in the family Hygrophoraceae. Found in the Galapagos, it was formally described as a new species in 2016 by Manuela Dal Forno, Frank Bungartz, and Alba Yánez-Ayabaca. The specific epithet santacruzensis refers to Santa Cruz Island, the type locality where the lichen was first documented scientifically. Here it was found at an abandoned farm behind El Puntudo, where it was growing on a shaded branch of an avocado tree. A paratype specimen was collected from a Cinchona tree. The lichen is one of two presumably endemic Cora species found on the Galapagos; the other is Cora glabrata.
Cora lawreyana is a species of basidiolichen in the family Hygrophoraceae. Found in Mexico, it was formally described as a new species in 2019 by Bibiana Moncada, Rosa Emilia Pérez-Pérez, and Robert Lücking. The type specimen was collected in the La Cortadura Ecological Reserve in a cloud forest at an altitude of 2,088 m (6,850 ft). It is only known to occur at the type locality, where it grows as an epiphyte on the trunks of trees, usually on or around mosses and liverworts, such as from the genera Frullania, Metzgeria, and Plagiochila. The specific epithet honours lichenologist James D. Lawrey, who, according to the authors, "has made numerous contributions to lichenology in such diverse fields as ecology, lichenicolous fungi, and the evolution of basidiolichens and their photobionts".
Cora byssoidea is a species of basidiolichen in the family Hygrophoraceae. Found in Colombia, it was formally described as a new species in 2013 by lichenologists Robert Lücking and Bibiana Moncada. The type specimen was collected in Páramo El Verjón at an altitude of 3,200 m (10,500 ft). Here it was found growing as an epiphyte on twigs and small branches of páramo vegetation. The lichen is only known from the type locality. The specific epithet byssoidea refers to the byssoid surface of the upper thallus. This surface comprises an irregularly dissolved layer of single hyphae in the cortex. A lookalike species, Cora hirsuta, also found at the same location, has a similar surface texture. In this lichen the surface is made of erect trichomes of agglutinated hyphae; despite their similarities, the two species are not closely related.
Cora cyphellifera is a species of basidiolichen in the family Hygrophoraceae. Found in northern Ecuador, it was formally described as a new species in 2013 by Manuela Dal-Forno, Frank Bungartz, and Robert Lücking. The type specimen was collected near the entrance to the Alto Choco Reserve at an elevation of 2,053 m (6,736 ft). Here, in open, disturbed forest patches, the lichen grows as an epiphyte on tree branches and twigs, forming foliose, light bluish-green thalli up to 15 cm (6 in) across, and comprising 20 to 30 semicircular lobes in each thallus. Cora cyphellifera is only known to occur at the type locality, which is a montane rainforest. The specific epithet refers to the unusual cyphelloid structure of the thallus; this characteristic is otherwise unknown in the genus Cora. According to the authors, "it almost looks like the lichenized thallus is parasitized by a non-lichenized, cyphelloid mushroom".
Cora inversa is a species of basidiolichen in the family Hygrophoraceae. Found in Colombia, it was formally described as a new species in 2013 by lichenologists Robert Lücking and Bibiana Moncada. The type specimen was collected in the Páramo El Verjón at an altitude of 3,200 m (10,500 ft). Here the lichen grows as an epiphyte, typically at the base of páramo shrubs, and often between bryophytes. The specific epithet refers to the partially strigose underside, presenting in an inverse fashion compared to Cora hirsuta, which is strigose on the upper side.
Cora strigosa is a species of basidiolichen in the family Hygrophoraceae. Found in Peru, it was formally described as a new species in 2013 by Robert Lücking, Elias Paz, and Luis Salcedo. The type specimen was collected in Piscacucho at an altitude of about 2,700 m (8,900 ft). Here, in montane rainforest and pasture near Machu Picchu, the lichen grows on rocks together with other lichens, such as Hypotrachyna and Rimelia. Cora strigosa is only known to occur at the type locality. The specific epithet strigosa refers to the strigose upper surface of the thallus, especially prominent where they project radially at the margins. This lichen resembles Cora hirsuta, but it is not closely related.
Acantholichen pannarioides is a species of basidiolichen in the family Hygrophoraceae, and the type species of genus Acantholichen. The lichen has a bluish-tinged, gelatinous thallus with a surface texture that has a powdery to hairy texture. It is found in montane regions of Central America and northern South America, where it grows on forest litter, bark, on bryophytes, and on other lichens.
Dictyonema barbatum is a species of basidiolichen in the family Hygrophoraceae. It is endemic to the Galápagos Islands, where it grows as an epiphyte on the bark of branches and trunks, often on introduced plants such as avocado and guava trees. It was formally described as a new species in 2017 by Manuela Dal-Forno, Frank Bungartz, and Robert Lücking. The type specimen was collected near the southern crater rim of the Sierra Negra, at an altitude of 1,055 m (3,461 ft). Its preferred habitat is open areas with lots of rainfall and light exposure. The lichen forms shelf-like, filamentous brackets comprising individual semicircular lobes up to 8 cm (3 in) wide. The specific epithet barbatum refers to the "beard-like" white hairs on the shelf margins, a characteristic feature of this species. These "hairs" are sheaths of fungal hyphae that lack photobiont filaments.
Dictyonema darwinianum is a species of basidiolichen in the family Hygrophoraceae. It is endemic to the Galápagos Islands, where it grows as an epiphyte on the bark of branches and trunks, often closely associated with or overgrowing bryophytes and interspersed detritus. It was formally described as a new species in 2017 by Manuela Dal-Forno, Frank Bungartz, and Robert Lücking. The type specimen was collected along the trail from Bellavista to El Puntudo on Santa Cruz Island at an altitude of 502 m (1,647 ft). The lichen is common and widespread on the Galápagos Islands, where it forms dark bluish-green filamentous and crust-like mats on Frullania liverworts and associated forest detritus. The specific epithet darwinianum honours Charles Darwin and the Charles Darwin Foundation.
Dictyonema lawreyi is a species of basidiolichen in the family Hygrophoraceae. Found in the United States, it was formally described as a new species in 2019 by Manuela Dal Forno, Laurel Kaminsky, and Robert Lücking. The type specimen was collected in Ocala National Forest, where it was growing as an epiphyte on a trunk of Magnolia. It is only known to occur here and in two other locations in Florida, all in hardwood forests. The lichen has a crustose and filamentous growth form on a white hypothallus, and thallus surface made of a mat of turquoise, loosely interwoven fibrils forming more or less continuous patches up to 5 cm (2 in) long. The type was collected by lichenologist James D. Lawrey, for whom the species is named, and whose work, according to the authors, "helped to redefine the circumscription of the genus Dictyonema s.str."
Dictyonema subobscuratum is a species of basidiolichen in the family Hygrophoraceae. It is endemic to the Galápagos Islands, where it mostly grows as an epiphyte over bryophytes on branches and trunks in humid zones. It was formally described as a new species in 2017 by Manuela Dal-Forno, Frank Bungartz, and Robert Lücking. The type specimen was collected on Floreana Island along the rim trail to Cerro Pajas at an altitude of 442 m (1,450 ft); it has also been recorded from Santa Cruz Island. The lichen forms dark bluish-green filamentous, irregular mats that grow in patches up to 5 cm (2.0 in) across. The specific epithet subobscuratum refers to its similarity with Dictyonema obscuratum, found in Brazil.
Parmotrema lawreyi is a species of corticolous (bark-dwelling), foliose lichen in the family Parmeliaceae. Found on the Galápagos Islands, it was formally described as a new species in 2019 by lichenologists Frank Bungartz and Adriano Spielmann. The type specimen was collected by the first author from the foothills of Media Luna on San Cristóbal Island, where it was found in dry, open woodland growing on the trunk of Bursera graveolens. The species epithet honours the authors' colleague James D. Lawrey, "on the occasion of his 70th birthday".
Cyphellostereum jamesianum is a species of basidiolichen belonging to the family Cyphellaceae that was described as new to science in 2019. It has been found in South Carolina and in Florida on a Taxodium wetland fragment at Florida Gulf Coast University. The species was named for James D. Lawrey.
