Cetraria islandica, also known as true Iceland lichen or Iceland moss, is an Arctic-alpine lichen whose erect or upright, leaflike habit gives it the appearance of a moss, where its name likely comes from.

Phaeogalera is a small genus of slender, fleshy bog and swamp-inhabiting mushrooms with large, brownish spores with a germ pore and a hymenium lacking chrysocystidia. Phaeogalera resemble Galerina in their habitat, macroscopic appearance, and spore print color, however, their microscopic characteristics more closely resemble Psilocybe. The type species, Phaeogalera stagnina, has an Arctic-alpine distribution in the Northern Hemisphere extending into the boreal forests and taiga. It grows along the edges of bogs in peaty soils and sometimes amongst Sphagnum or other mosses. This type species has been classified in Galerina, Tubaria and Psilocybe. Modern molecular evidence supports the recognition of Phaeogalera as an independent genus separate from Galerina. The generic name is built upon the antiquated generic name "Galera", now synonymous with Galerina, and with a reference to the darker colors of the basidiospores of Phaeogalera. When originally proposed by Kühner, he forgot to fully cite the original publication for the type species which explains by the name was later validly published by Pegler & Young in 1975. The genus Meottomyces was segregated from Phaeogalera after briefly being classified together by Romagnesi.
Mireya Dorotea Correa Arroyo was a Panamanian botanist and plant taxonomist known for her work with the flora of Panama.
Lecanora polytropa, commonly known as the granite-speck rim lichen, is a species of saxicolous lichen in the family Parmeliaceae. A small, inconspicuous species that grows in the cracks of rock surfaces, it has a cosmopolitan distribution and has been recorded on all continents, including Antarctica.
Teuvo ("Ted") Tapio Ahti is a Finnish botanist and lichenologist. He has had a long career at the University of Helsinki that started in 1963, and then following his retirement in 1997, at the Botanical Museum of the Finnish Museum of Natural History. Known as a specialist of the lichen family Cladoniaceae, Ahti has published more than 280 scientific publications. A Festschrift was dedicated to him in 1994, and in 2000 he was awarded the prestigious Acharius Medal for lifetime contributions to lichenology.
Per Magnus Jørgensen is a Norwegian botanist and lichenologist, and Professor Emeritus of systematic botany at the University of Bergen. He is known for his work on the lichen families Pannariaceae and Collemataceae. Jørgensen was awarded the Acharius Medal in 2021 for his lifetime contributions to lichenology.
Ascobolus immersus is a species of fungus belonging to the family Ascobolaceae.
Gunnar Bror Fritiof Degelius was a Swedish lichenologist. Between the publications of his first and final scientific papers, Degelius had a 70-year-long research career. While he was best known for his expertise on the lichen genus Collema, he also wrote important papers on lichen biology and ecology, floristic studies of the Nordic countries and various other areas around the world, and lichen succession. Degelius described 124 new taxa, and published about 130 scientific papers. In 1992 he was one of the first to be awarded the Acharius Medal for his lifetime contributions to lichenology. Fifteen species and three genera have been named in honour of Degelius.
Stereocaulon alpinum is a species of fungus belonging to the family Stereocaulaceae. It is similar to Stereocaulon paschale but differs from it in containing cyanobacteria of the genus Nostoc while S. paschale contains cyanobacteria of the genus Stigonema, which have a darker colour than Nostoc.
Carbonea supersparsa is a species of lichenicolous fungus belonging to the family Lecanoraceae. It is widespread in the Northern Hemisphere. In Iceland it has been reported growing on Lecanora cenisia near Egilsstaðir and Lecanora polytropa near Seyðisfjörður.
Veli Johannes Paavo Bartholomeus Räsänen was a Finnish lichenologist.
Lichenopeltella cetrariicola is a species of lichenicolous fungus belonging to the class Dothideomycetes. It has been reported from Europe and Iceland but it probably has a more widespread distribution. It has been reported from at least two host species, Cetraria islandica and Cetraria aculeata.
Muellerella pygmaea is a species of lichenicolous fungus in the family Verrucariaceae. It has a cosmopolitan distribution in Arctic-alpine areas and grows on the thallus and apothecia of a number of hosts.
Ascobolus brantophilus is a species of coprophilous fungus in the family Ascobolaceae. It grows on goose droppings.
Alfred Mycolayovych Oxner was a Ukrainian botanist and lichenologist. His research covered various areas: floristics, taxonomy, phylogenetics, phytogeography, and phytosociology. Oxner founded the National Lichenological Herbarium of Ukraine.
Klára Anna Verseghy was a Hungarian lichenologist. She was the curator of the lichen collection of the Hungarian Natural History Museum in Budapest from 1958 to 1985.
