Loxospora ochrophaea is a species of crustose lichen in the family Sarrameanaceae.
It was first described scientifically by American lichenologist Edward Tuckerman in 1848 as Biatora ochrophaea. [2] It has been shuffled to various genera in its taxonomic history, including Lecanora , Haematomma , and Lecania . [1] Richard Harris proposed a transfer to Loxospora in 1990. [3]
Loxospora ochrophaea has a crust-like thallus that is light gray to green with a warty texture. It has peach-coloured apothecia that have a white margin. The lichen contains thamnolic acid and zeorin as secondary compounds. Found in North America, it grows on bark. [4]
Charles Christian Plitt was a botanist and lichenologist. Species of lichens that have been named in Charles Plitt's honor are: Pyrenula plittii R.C.Harris, Xanthoparmelia plittii (Gyelnk) Hale, and Pertusaria plittiana Erichsen.
Speerschneidera is a single-species genus of lichen-forming fungi in the family Leprocaulaceae. The genus was circumscribed by Italian botanist Vittore Benedetto Antonio Trevisan de Saint-Léon in 1861, with Speerschneidera euploca as the type species. This lichen was originally described by Edward Tuckerman in 1858 as Physcia euploca. It is a crustose lichen found in the southern United States and Mexico.
Candelariella is a genus of bright yellow, ocher, or greenish yellow crustose or squamulose lichens in the family Candelariaceae. Members of the genus are commonly called eggyolk lichens, goldspeck lichens, or yolk lichens. The genus was circumscribed in 1894 by Swiss lichenologist Johannes Müller Argoviensis, with Candelariella vitellina assigned as the type species.
Chrysothrix is a genus of lichen-forming fungi in the family Chrysothricaceae. They are commonly called gold dust lichens or sulfur dust lichens, because they are bright yellow to greenish-yellow, sometimes flecked with orange, and composed entirely of powdery soredia. Apothecia are never present in North American specimens.
Pilophorus acicularis, commonly known as the nail lichen or the devil's matchstick lichen, is a species of matchstick lichen in the family Cladoniaceae.
Mason Ellsworth Hale, Jr. was one of the most prolific lichenologists of the 20th century. Many of his scholarly articles focused on the taxonomy of the family Parmeliaceae. Hale was one of the first lichen experts to incorporate secondary chemistry and technology such as computers and scanning electron microscopy into taxonomic work. Mason Hale published approximately two hundred articles and books on various aspects of lichen biology including taxonomy, anatomy, chemistry, and ecology. Hale also wrote several books aimed at education and increasing accessibility to lichens.
Vermilacinia cephalota is a fruticose lichen usually found on trees, shrubs and wooden fences in the fog regions along the Pacific Coast of North America from southeastern Alaska to the Vizcaíno Peninsula of Baja California.
Robert "Bob" Shaw Egan is a botanist and lichenologist, specializing in the family Parmeliaceae. He was the president of the American Bryological and Lichenological Society from 1999 to 2001.
Amandinea milliaria is a species of corticolous lichen in the family Caliciaceae. It was originally described as a species of Rinodina by Edward Tuckerman in 1877. Philip F. May and John Wilson Sheard transferred it to Amandinea in 1997. The lichen is found in the east coast of North America, ranging from Prince Edward Island south to Texas, and includes the Great Lakes region.
Pyxine subcinerea is a species of foliose lichen in the family Caliciaceae. It has a pantropical distribution, and typically grows on bark, but less commonly on rocks. The lichen is characterised by its yellow medulla, soralia on the margins on the lobes that make up the thallus, and the presence of the chemical lichexanthone in the cortex.
Punctelia rudecta, commonly known as the rough speckled shield or the speckleback lichen, is a North American species of foliose lichen in the family Parmeliaceae. This species can be readily identified by the light color of the thallus underside, the relatively large lobes at the edges of the thallus, and the tiny white pores present on the top of the thallus that are characteristic of the genus Punctelia. The lichen is quite abundant and widespread in the eastern and southeastern United States, although it also occurs in Canada and northern Mexico, but is less common in these regions. The lichen usually grows on bark, and less commonly on shaded rocks. There are several lookalike Punctelia species; these can often be distinguished from P. rudecta by differences in distribution or in the nature of the reproductive structures present on the thallus.
Punctelia bolliana, the eastern speckled shield lichen, is a species of foliose lichen in the family Parmeliaceae. It is found in North America, with a distribution extending from the Canadian province of Ontario south to the central and northeastern United States and Mexico. It grows on the bark of both deciduous trees and coniferous trees. The combination of characteristics that distinguishes this species from others in genus Punctelia are the absence of the vegetative propagules isidia and soralia, a pale brown lower thallus surface, and the presence of the secondary chemical protolichesterinic acid in the medulla.
Punctelia graminicola is a species of foliose (leafy) lichen in the family Parmeliaceae. It grows on rocks, and, less frequently, on bark in North America, South America, and East Africa. It has a blue-grey thallus measuring up to about 15 cm (6 in), covered with tiny pores called pseudocyphellae. Sometimes the lichen forms small lobes that project out from the surface. Fruiting bodies are uncommon in this species; if present, they resemble small cups with a brown internal disc measuring 3–10 mm (0.1–0.4 in) in diameter. A lookalike species, Punctelia hypoleucites, is not readily distinguishable from Punctelia graminicola by appearance or habitat alone; these species can only be reliably differentiated by examining the length of their conidia.
Calicium carolinianum is a species of lichen in the family Caliciaceae. It is endemic to the Gulf Coastal Plain region of the United States. The lichen contains norstictic acid, and has ascospores that measure 13–17 by 8–9 μm.
Loxospora is a genus of lichen-forming fungi in the family Sarrameanaceae. It has 13 species. The genus was circumscribed by Italian lichenologist Abramo Bartolommeo Massalongo in 1852, with Loxospora elatina assigned as the type species. This crustose lichen was originally named Lecanora elatina by Erik Acharius in 1810.
Loxospora cristinae is a fungal species classified in 2018, found in a few European countries. It belongs to the division Ascomycota and the family Sarrameanaceae. It was first identified and described in the 19th century, but the species would not be correctly classified until almost two centuries later. Loxospora cristinae is a sterile crustose lichen, meaning it reproduces by a type of vegetative spore that has evolved specifically to produce morphological structures.
Xanthoparmelia joranadia is a lichen which belongs to the Xanthoparmelia genus. The lichen is rare and is listed as imperiled by the Nature Conservatory. It is noted for being similar to Xanthoparmelia arida and Xanthoparmelia lecanorica.
Xanthoparmelia arida is a lichen which belongs to the Xanthoparmelia genus. The lichen is an arid shield lichen and is uncommon it is listed as apparently secure by the Nature Conservatory. It is noted for being similar to Xanthoparmelia joranadia.
Xanthoparmelia lecanorica is a lichen which belongs to the Xanthoparmelia genus. It is noted for being similar in appearance and has often been misidentified as Xanthoparmelia arida.
Pyrenula cruentata is a species of corticolous (bark-dwelling), crustose lichen in the family Pyrenulaceae. The lichen, characterized by its crimson-colored thallus and perithecial warts, has a neotropical distribution.
