Lobaria is a genus of foliose lichens, formerly classified in the family Lobariaceae, but now placed in the Peltigeraceae. They are commonly known as "lung wort" or "lungmoss" as their physical shape somewhat resembles a lung, and their ecological niche is similar to that of moss.
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.
Menegazzia is a genus of lichenized fungi containing roughly 70 accepted species. The group is sometimes referred to as the tree flutes, honeycombed lichens, or hole-punch lichens. The most obvious morphological feature of the genus is the distinctive perforations spread across the upper side of the thallus. This makes the group easy to recognise, even for those not particularly familiar with lichen identification.
Hypogymnia pseudocyphellata is a rare species of foliose lichen in the family Parmeliaceae. Found only in the Chinese Himalayas, it was described as a new species by Bruce McCune and Erin Martin in 2003. The type specimen was collected from the Tian Chi alpine lake in Shangri-La City (Yunnan), at an elevation of 3,750 metres (12,300 ft). Here it was found growing on the bark and wood of fir. The lichen is characterized by the presence of whitish pseudocyphellae on the tips of the lobes ; rimmed holes; lobes that are narrow and separated; and a complex secondary chemistry with several unknown chemical compounds as well as barbatic acid, but without diffractaic acid.
Hypogymnia congesta is a rare species of foliose lichen in the family Parmeliaceae. Found in China, it was formally described as a new species in 2003. The lichen grows on the bark and wood of conifers and bamboo. Hypogymnia congesta has a brown to brownish-grey foliose thallus measuring up to 8 cm (3.1 in) long or broad, with a cartilage-like texture. The lichen is chemically distinct, containing physodic acid and virensic acid; the latter substance is otherwise unknown from genus Hypogymnia.
Hypogymnia krogiae, commonly known as the freckled tube lichen, is a species of foliose lichen in the family Parmeliaceae. Found in North America, it was described as a new species in 1973 by Karl Ohlsson. The type specimen was collected near Cheat Bridge, West Virginia by Mason Hale in 1956.
Hypogymnia flavida is a species of foliose lichen in the family Parmeliaceae. It is found in mountainous locations of east Asia, where it grows on the bark and wood of woody plants. It has a relatively large yellowish thallus.
Opegrapha verseghyklarae is a little-known species of lichenicolous (lichen-eating) fungus in the family Teloschistaceae. It is found in the Russian Far East, where it grows on the thalli and apothecia of the crustose lichen Ochrolechia pallescens.
Oxneria ussuriensis is a species of corticolous, crustose lichen in the family Teloschistaceae. It is found in a single location in the Russian Far East.
Rostania is a genus of lichen-forming fungi in the family Collemataceae. These lichens are primarily found on tree bark, occasionally on wood, with one species known to inhabit soil. The genus is characterized morphologically by having minute thalli made of hyphal tissue without a separate cortex, and the more or less cuboid-shaped ascospores.
Pertusaria albineoides is a species of corticolous (bark-dwelling), crustose lichen in the family Pertusariaceae. Found on the Galápagos Islands, it was formally described as a new species in 2015 by Frank Bungartz, A.W.Archer, Alba Yánez-Ayabaca, and John Elix. The type specimen was collected on Alcedo Volcano at an altitude of 1,089 m (3,573 ft), where it was found growing on a partially shaded, rain- and wind-exposed trunk of Scalesia microcephala. The species epithet refers to the similarity to the species Pertusaria albinea, from which it differs by having thin-walled ellipsoid-shaped ascospores that are longer and narrower.
Pertusaria cerroazulensis is a species of corticolous (bark-dwelling), crustose lichen in the family Pertusariaceae. Found on the Galápagos Islands, it was formally described as a new species in 2015 by Frank Bungartz, Alan W. Archer, Alba Yánez-Ayabaca, and John Elix. The type specimen was collected from the Cerro Azul volcano at an altitude of 1,038 m (3,406 ft), where in a small, shaded woodland, it was growing on twigs of Psidium galapageium. The species epithet refers to the type locality.
Peltigera koponenii is a species of foliose lichen in the family Peltigeraceae. Found in Papua New Guinea, it was formally described as a new species in 2009 by Emmanuël Sérusiaux, Bernard Goffinet, Jolanta Miądlikowska, and Orvo Vitikainen. The type specimen was collected near Lake Wanba at an altitude of 2,400–2,500 m (7,900–8,200 ft), where it was found growing on a tree trunk in an open montane forest of Nothofagus and Pandanus. The species epithet honours Finnish bryologist Timo Koponen, "who made large and well processed collections of Peltigera in Papua New Guinea".
Peltigera montis-wilhelmii is a rare species of corticolous (bark-dwelling), foliose lichen in the family Peltigeraceae. Found in Papua New Guinea, it was formally described as a new species in 2009 by Emmanuël Sérusiaux, Bernard Goffinet, Jolanta Miądlikowska, and Orvo Vitikainen. The type specimen was collected from Pindaunde valley on Mount Wilhelm at an altitude of 3,600 m (11,800 ft). The species epithet refers to the type locality.
Byssoloma fuscothallinum is a species of foliicolous (leaf-dwelling) lichen in the family Pilocarpaceae. Found in Colombia and French Guiana, it was formally described as a new species in 2006 by lichenologist Robert Lücking.
Calopadia saxicola is a species of saxicolous (rock-dwelling) crustose lichen in the family Pilocarpaceae. It is found on the rocky shores of southern Brazil, where it thrives in the shade of vegetated zones and grows directly on rocks away from other crustose lichens. The lichen was formally described as a new species in 2015. Calopadia saxicola stands out from its close relatives due to its well-defined thallus, reddish-brown disc, thicker hymenium, and smaller conidia.
Hypogymnia capitata is a species of foliose lichen in the family Parmeliaceae. Found in high-elevation conifer forests in Sichuan Province, China, it was described as a new species in 2014. The lichen is characterized by its capitate terminal soralia, brownish lobes with white cavities, and the presence of olivetoric acid. This lichen is distinguished from similar species by its specific morphological, chemical, and habitat characteristics.
Hypogymnia nitida is a species of foliose lichen in the family Parmeliaceae. It has a glossy dark brown upper surface and a strongly wrinkled, convoluted lower surface. Found in China, it was described as a new species in 2014.
Hypogymnia pendula is a rare species of foliose lichen in the family Parmeliaceae. It is characterised by its pendulous (hanging) growth form and distinct chemical composition.
Hypogymnia saxicola is a rare species of foliose lichen in the family Parmeliaceae. Found in Yunnan and Sichuan provinces of China, it forms delicate cushions on mossy rocks in subalpine regions. It is characterised by its slender, glossy brown lobes and unique chemistry.
