Graphis is a genus of lichenized fungi in the family Graphidaceae.
Sagema is a fungal genus in the family Lecanoraceae. It is a monotypic genus, containing a single species, the crustose lichen Sagema potentillae, found in Nepal. Both the genus and species were described in 1993 by lichenologists Josef Poelt and Martin Grube.
Skyttella is a genus of lichenicolous fungi in the family Cordieritidaceae. It contains two species. The genus was circumscribed in 1988 by David Leslie Hawksworth and Rolf Santesson, with Skyttella mulleri assigned as the type species. This species, which parasitizes the lobes of foliose lichens in the genus Peltigera, was previously classified in the genus Phacopsis. Skyttella stictae, an Ecuadorian species that grows on Sticta, was added to the genus in 2017.
Sagiolechia is a genus of lichen-forming fungi in the family Sagiolechiaceae. The genus was circumscribed by lichenologist Abramo Bartolommeo Massalongo in 1854, who assigned Sagiolechia protuberans as the type species. The family Sagiolechiaceae was proposed in 2010 to contain Sagiolechia as the type genus, and genus Rhexophiale; molecular phylogenetic analysis showed that these two genera formed a distinct clade in the Ostropales.
Leptochidium is a genus of lichen-forming fungi in the family Massalongiaceae. It has two species:
Rhizocarpon is a genus of crustose, saxicolous, lecideoid lichens in the family Rhizocarpaceae. The genus is common in arctic-alpine environments, but also occurs throughout temperate, subtropical, and even tropical regions. They are commonly known as map lichens because of the prothallus forming border-like bands between colonies in some species, like the common map lichen.
Lepraria is a genus of leprose crustose lichens that grows on its substrate like patches of granular, caked up, mealy dust grains. Members of the genus are commonly called dust lichens. The main vegetative body (thallus) is made of patches of soredia. There are no known mechanisms for sexual reproduction, yet members of the genus continue to speciate. Some species can form marginal lobes and appear squamulose. Because of the morphological simplicity of the thallus and the absence of sexual structures, the composition of lichen products are important characters to distinguish between similar species in Lepraria.
Brignall Banks is a Site of Special Scientific Interest in the Teesdale district of south-west County Durham, England. It consists of a narrow belt of woodland on the steep slopes of the valleys of the River Greta and its tributary, Gill Beck, just west of Brignall village and about 6 km south of Barnard Castle.
Trollskogen is a windswept, grazed pine forest and nature reserve in the northeast corner of the Baltic island Öland, Sweden. The forest is on a promontory with an exposed shingle beach on the eastern side, the side of the Baltic Sea, and a sheltered bay on the western side, of Grankullaviken bay. The 100-hectare (250-acre) reserve, formerly a Domänreservat, is part of the Böda Kronopark. Its southeastern boundary is also the north border of the nature reserve Bödakusten östra.
Eilif Dahl was a Norwegian botanist and politician for the Labour Party.
A script lichen, or graphid lichen, is a member of a group of lichens which have spore producing structures that look like writing on the lichen body. The structures are elongated and narrow apothecia called lirellae, which look like short scribbles on the thallus. "Graphid" is derived from Greek for "writing". An example is Graphis mucronata.
A corticolous lichen is a lichen that grows on bark. This is contrasted with lignicolous lichen, which grows on wood that has had the bark stripped from it, and saxicolous lichen, which grows on rock.
Biatora aureolepra is a species of fungus within the family Ramalinaceae, first found in inland rainforests of British Columbia.
Arctoparmelia separata, commonly known as the rippled ring lichen, is a species of foliose, ring lichen in the family Parmeliaceae with a roughly circumpolar distribution.
Bould Wood is a 58.2-hectare (144-acre) biological Site of Special Scientific Interest north of Shipton-under-Wychwood in Oxfordshire. An area of 23 hectares is Foxholes nature reserve, which is managed by the Berkshire, Buckinghamshire and Oxfordshire Wildlife Trust.
Orvo Vitikainen is a Finnish lichenologist. He entered the University of Helsinki in 1961, from where he obtained a Candidate of Philosophy degree in 1966, and a Licentiate of Philosophy in 1971. He later earned a Ph.D. from this institution in 1994, under the supervision of Teuvo Ahti. Between the years 1961 and 1981 he was a junior curator of cryptogams at the University of Helsinki Botanical Garden, and then from 1983 to 2004 he was the head of the lichen herbarium. Here he managed the internationally valuable collections of the early lichenologists Erik Acharius and William Nylander. He has collected thousands of specimens for the herbarium from various locations in Finland, but also internationally, including Sweden, Norway, Denmark, Russian Karelia, Scotland, Austria, Italy, Hungary, Croatia, Montenegro, Tanzania, Kenya, British Columbia, and Brazil. In 1992–1994, he was a scientist of the Finnish Academy in the Ahti research group.
Parmelia ernstiae is a species of foliose lichen in the family Parmeliaceae. It occurs in Europe.
Chrysothrix flavovirens is a species of crustose and corticolous (bark-dwelling) lichen in the family Chrysotrichaceae. It was formally described as a new species in 1994 by Tor Tønsberg as the sorediate counterpart of the common and widespread Chrysothrix candelaris. The type specimen was collected from Kirkeøy, Norway, where it was found growing on Picea abies. It has a pale greenish-yellow thallus that contains rhizocarpic acid. The lichen is widespread in Europe, and has also been recorded from Japan and North America. In the Atlantic and Mediterranean biogeographic regions of Portugal, it prefers to grow on the acidic bark of coastal conifer trees.
Cercidospora thamnoliicola is a species of lichenicolous fungus in the genus Cercidospora but it has not been assigned to a family. It is known to parasitise the lichen Thamnolia vermicularis in Iceland but it is rare there. The species was first formally described by mycologist Per G. Ihlen in 1995, from specimens growing on Thamnolia vermicularis in Norway.
Heteroacanthella ellipsospora is a species of fungus of uncertain familial placement in the order Auriculariales. The fungus is lichenicolous (lichen-dwelling), and it parasitises the apothecia and thallus of the crustose lichen Lecanora carpinea. Heteroacanthella ellipsospora was formally described as a new species in 2014 by Juan Carlos Zamora, Sergio Pérez-Ortega and Víctor Rico. It was first described from specimens collected in the Spanish provinces of Jaén and Madrid, and later reported from Sweden.
