Ahtiana is a genus of lichenized fungi known as candlewax lichens in the family Parmeliaceae. [1] A monotypic genus, it contains the single species Ahtiana sphaerosporella or the mountain candlewax lichen, [2] found in western North America. This species was segregated from the genus Parmelia by the Canadian lichenologist Trevor Goward in a 1985 publication. [3] It had been suggested that the genus include A. aurescens (Eastern candlewax lichen, [2] formerly Cetraria aurescens Tuck.) and A. pallidula (pallid candlewax lichen, [2] formerly Cetraria pallidula Tuck.) based on similarities in morphology, [4] but this transfer is not supported by molecular analysis. [5]

The genus was named in honour of Finnish botanist Teuvo Tapio Ahti. [3]

<i>Parmelia</i> (fungus) Genus of lichens

Parmelia is a genus of medium to large foliose (leafy) lichens. It has a global distribution, extending from the Arctic to the Antarctic continent but concentrated in temperate regions. There are about 40 species in Parmelia. In recent decades, the once large genus Parmelia has been divided into a number of smaller genera according to thallus morphology and phylogenetic relatedness.

<span class="mw-page-title-main">Parmeliaceae</span> Family of lichens

The Parmeliaceae is a large and diverse family of Lecanoromycetes. With over 2700 species in 71 genera, it is the largest family of lichen-forming fungi. The most speciose genera in the family are the well-known groups: Xanthoparmelia, Usnea, Parmotrema, and Hypotrachyna.

<i>Hypogymnia</i> Genus of lichens

Hypogymnia is a genus of foliose lichens in the family Parmeliaceae. They are commonly known as tube lichens, bone lichens, or pillow lichens. Most species lack rhizines that are otherwise common in members of the Parmeliaceae, and have swollen lobes that are usually hollow. Other common characteristics are relatively small spores and the presence of physodic acid and related lichen products. The lichens usually grow on the bark and wood of coniferous trees.

<i>Vulpicida</i> Genus of lichen

Vulpicida is a genus of lichenized fungi in the family Parmeliaceae. Circumscribed in 1993 to contain species formerly placed in Cetraria, the genus is widespread in Arctic to northern temperate regions, and contains six species. The genus is characterized by the presence of the secondary metabolites pulvinic acid and vulpinic acid, compounds that when combined with usnic acid, give the species their characteristic yellow and green colors.

Tuckermannopsis is a genus of foliose lichens in the family Parmeliaceae.

Tuckneraria is a genus of lichen-forming fungi in the family Parmeliaceae.

<i>Cetrelia</i> Genus of lichens in the family Parmeliaceae

Cetrelia is a genus of leafy lichens in the large family Parmeliaceae. They are commonly known as sea-storm lichens, alluding to the wavy appearance of their lobes. The name of the genus, circumscribed in 1968 by the husband and wife lichenologists William and Chicita Culberson, alludes to the former placement of these species in the genera Cetraria and Parmelia.

Coelopogon is a genus of lichen-forming fungi in the family Parmeliaceae. The genus contains two species found in southern South America and South Africa.

<i>Esslingeriana</i> Single-species genus of lichen

Esslingeriana is a fungal genus in the family Parmeliaceae. The genus is monotypic, containing the single foliose lichen species Esslingeriana idahoensis, commonly known as the tinted rag lichen. It is found in northwestern North America.

<i>Cetraria aculeata</i> Species of lichenised fungus in the family Parmeliaceae

Cetraria aculeata or the spiny Iceland lichen is a dark brown to black fruticose, soil Iceland lichen from the family Parmeliaceae. The species was first described by German naturalist Johann Christian Daniel Edler von Schreber in 1771 under the name of Lichen aculeatus. Later on, Erik Acharius, the "father of lichenology" gave it a name of Cornicularia aculeata, which lately has been changed to Coelocaulon aculeatum. Finally, the taxonomic revision of Ingvar Kärnefelt and colleagues assigned the species to the genus Cetraria.

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.

<i>Usnea fulvoreagens</i> Species of lichen in the family Parmeliaceae

Usnea fulvoreagens is a species of beard lichen in the family Parmeliaceae. It was first described by Finnish lichenologist Veli Räsänen in 1931 as a variety of Usnea glabrescens. He raised it to distinct species status in 1935. The lichen has a shrubby thallus that is richly branched, and bases that are blackened. The presence of norstictic acid is often used to differentiate this species from other similar species. It has a widespread distribution in Europe.

<i>Usnocetraria</i> Genus of lichen

Usnocetraria is a small genus of lichen-forming fungi in the family Parmeliaceae. It contains two species of corticolous (bark-dwelling), foliose lichens.

<i>Cetraria arenaria</i> Species of lichen

Cetraria arenaria, commonly known as the sand-loving Iceland lichen, is a species of terricolous (ground-dwelling), fruticose lichen in the family Parmeliaceae. It was formally described as a new species in 1977 by the Norwegian lichenologist Ingvar Kärnefelt. The type specimen was collected in 1949 by Henry Imshaug from Mackinac County, Michigan, where he found it growing on sandy soil.
