Parmeliaceae

Lethariella is a genus of fruticose lichens in the family Parmeliaceae. The genus was originally proposed as a subgenus of Usnea by Polish lichenologist Józef Motyka in his 1936 monograph of that genus. Norwegian botanist Hildur Krog elevated the taxon to generic status in 1976.

Dactylina is a genus of lichen-forming fungi in the family Parmeliaceae. The genus was circumscribed by Finnish botanist William Nylander in 1860, with Dactylina arctica assigned as the type species.

Canoparmelia is a genus of lichen-forming fungi in the family Parmeliaceae. The widespread genus contains about 35 species. Canoparmelia, a segregate of the parmelioid lichen genus Pseudoparmelia, was circumscribed by John Elix and Mason Hale in 1986.

Montanelia is a genus of lichen-forming fungi belonging to the large family Parmeliaceae. The genus comprises foliose lichens recognised by its short, narrow with flat to slightly convex edges; a smooth, unperforated outer skin (); shallow, irregular pseudocyphellae—tiny pores—on the upper surface; slender, cylindrical to spindle-shaped asexual spores (conidia); and a white medulla that contains orcinol depsides.

Gowardia is a genus of medium-sized, greyish hair lichens in the family Parmeliaceae. It is a circumpolar genus, mainly restricted to arctic-alpine habitats in northern Canada, Europe, and Russia.

Asahinea is a genus of lichen-forming fungi in the family Parmeliaceae. The genus has a widespread circumpolar distribution, and contains four species. The species form medium to large, leaf-like, yellowish to brownish crusts on rocks and plant debris in open arctic and alpine habitats, and can be conspicuous in the field; A. chrysantha in particular produces bright yellow rosettes that stand out against the tundra. The genus is named in honour of the Japanese lichenologist Yasuhiko Asahina, who made foundational contributions to the understanding of lichen chemistry in the twentieth cent

Pannoparmelia is a genus of lichenised ascomycetes in the large family Parmeliaceae. It is a genus of five currently accepted species. Pannoparmelia species have a foliose growth habit. All members of the family have a symbiotic association with green alga and the majority of Parmeliaceae species have foloiose. The morphological diversity is enormous within this group and the specimen are difficult to identify in its species level. There are a range of habitats and climatic regions within this family and it includes tropical rainforest trees to subshrubs in Arctic tundra.[3]

Ahtiana is a fungal genus in the family Parmeliaceae. A monotypic genus, it contains the single species Ahtiana sphaerosporella, the mountain candlewax lichen, found in western North America. The species was originally classified as Parmelia sphaerosporella by Johannes Müller Argoviensis in 1891, before Trevor Goward established the new genus Ahtiana in 1985, naming it after Finnish lichenologist Teuvo Ahti. This foliose lichen is characterised by its pale yellowish-green thallus, spherical spores, laminal apothecia (fruiting bodies), and the presence of usnic and caperatic acids. It primarily

Parmelinella is a genus of lichen belonging to the family Parmeliaceae. The genus was circumscribed in 1987 by John Elix and Mason Hale as a segregate of Parmelina, from which it differs in having larger ascospores and containing salazinic acid. Although the genus had been assumed to be well-defined morphologically, a 2021 molecular phylogenetic study suggests that the generic delimitations need to be revised.

Bulbothrix is a genus of lichen-forming fungi in the family Parmeliaceae. Established in 1974 by the American lichenologist Mason Hale as a segregate from the genus Parmelia, Bulbothrix comprises about 40 accepted species as of 2025. These foliose lichens are distinguished by their characteristic black, bulb-tipped hairs () along the lobe edges and are found roughly equally divided between the Old World and New World, growing predominantly on trees in lowland rainforests and shrublands.

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.

Everniopsis is a fungal genus in the family Parmeliaceae. It consists of a single species, the bark-dwelling lichen Everniopsis trulla, which occurs in Africa and South America.
