Vermilacinia, a genus of lichenized fungi in the family Ramalinaceae, is a yellow-green fruticose type of lichen with about 30 species that grow on rocks, trees, and soil within the fog zone along the Pacific Coast of North America and South America. The genus name refers to the thallus being divided into narrow worm-like (vermis) branches (lacinia);the latter part of the name (lacinia) generally applied in descriptions and taxonomic keys such as exemplified in a key to Sonoran Desert species of Ramalina.
Niebla is a genus of yellow-green fruticose lichens that grow on rocks, trees, and shrubs within the fog zone of coastal North America, or more narrowly defined to occur on rocks and soil along the Pacific Coast from Mendocino County in California south to Baja California Sur.
Niebla homalea is a species of fruticose lichen that grows on rocks in foggy areas along the Pacific Coast of North America, from Mendocino County, California south to Bahía de San Quintín on the main peninsula of Baja California, with an isolated occurrence further south on vertical rock faces above Punta Camachos, and other occurrences in the Channel Islands and on Guadalupe Island. The epithet homalea, given by Acharius, suggests it was in regard to the branches appearing flattened.
Vermilacinia acicularis is a fruticose lichen that occurs in the Channel Islands of California. The type specimen was collected from San Clemente Island. Other specimens have been collected from Santa Barbara Island and Anacapa Island.
Vermilacinia laevigata is a fruticose lichen that occurs in the fog zone along the Pacific Coast of the California Floristic Province from Marin County, California to 15 miles south of Misión San Vicente Ferrer in Baja California
Vermilacinia procera is a fruticose lichen of local occurrences on rocks near the sea along the Pacific Coast from San Francisco California to the Channel Islands, and to Punta Escarpada in Baja California. The species is also reported to occur further south to the Vizcaíno Peninsula and on Cedros Island, but these reports are controversial in view of different interpretations of the species that include V. pumila and V. paleoderma that were not recognized at the time V. procera was described ; for example, a specimen collected on Guadalupe Island by Weber and MCoy (L-3605, COLO that was cited by Phillip Rundel and Peter Bowler in 1994 as belonging to Niebla procera, whereas in a revision of the genus by Richard Spjut in 1996, it was cited as belonging to Vermilacinia paleoderma. Both authorities generally agree to some extent on the description of the species and its geographical range within the California Floristic Province.
Vermilacinia pumila is a whitish-green fruticose lichen that occurs in fog areas along the Pacific Coast and offshore islands of North America. The species epithet pumila refers to the dwarf form of the thallus, in contrast to V. combeoides.
Vermilacinia reptilioderma is a rare fruticose lichen found on the Vizcaíno Peninsula and Cedros Island of Baja California. The epithet, reptilioderma, is in regard to the outer surface of the cortex appearing like the skin of a reptile, especially the brown snake, Pseudechis australis, the color of the thallus cortex often turning brown when stored in a herbarium.
Vermilacinia rigida is a dark green, rare fruticose lichen that occurs in fog areas along the Pacific Coast of Baja California, known only from two locations about 100 km north of Guerrero Negro. The epithet, rigida, is in regard to its stiff thallus branches.
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.
Vermilacinia corrugata is a fruticose lichen that grows on trees and shrubs in the fog regions along the Pacific Coast of North America from the Channel Islands and San Diego in California to southern Baja California. The epithet is in reference to corrugated cortex of the species.
Vermilacinia flaccescens is a fruticose lichen that grows on cacti and shrubs in the fog regions along the Pacific Coast of South America, Peru, Chile and in the Juan Fernandez Islands The epithet is in reference to the flaccid thallus but some specimens have been interpreted to have rigid branches.
Vermilacinia howei is a fruticose lichen that grows on trees and shrubs in the fog regions along the Pacific Coast of North America in the coastal scrub region of the Channel Islands of California, and around Bahía de San Quintín, Baja California and further south in the Vizcaíno Desert. The epithet honors Reginald Heber Howe, Jr. for his contributions to lichenology, especially acknowledged for providing images of the type (biology) specimens in his revision of the genus Ramalina.
Vermilacinia leonis is a fruticose lichen usually found on branches of shrubs in the fog regions along the Pacific Coast of North America and South America; in North America it is found on the southern half of the main peninsula of Baja California north to the southern coast of the Vizcaíno Peninsula. In South America, it occurs on bushes and rocks in Chile; reported from Colchaqua (Valley) and Santiago The epithet is in regard to absence of the black transverse bands often seen in other species such as V. leopardina, V. tigrina and V. zebrina.
Vermilacinia leopardina is a fruticose lichen usually that grows abundantly on the branches of shrubs in the fog regions along the Pacific Coast of North America, in the Channel Islands and on the mainland of California from Santa Barbara County south to the Vizcaíno Peninsula of Baja California. The species is also reported to occur in Chile, based on a single specimen mounted on a large index card off to one corner with the type (biology) of Usnea tumidula in the center and bottom ; it is possible that the specimen of V. leopardina was from North America and placed on the card for the purpose of making a comparison to the type for Usnea tumidula, which was annotated Ramalina ceruchis var. gracilior Muell.Arg., a name of uncertain status. The epithet, leopardina, is in reference to the black transverse bands and irregularly shaped black spots commonly seen on the thallus branches that obviously imply a similarity to the leopard animal, while also making comparative distinctions to other black banded species: V. tigrina and V. zebrina, obviously to a tiger and zebra, and to V. leonis, obviously a lion, which has no black stripes.
Vermilacinia nylanderi is a fruticose lichen that grows on branches of shrubs in the fog regions along the Pacific Coast of North America in the Channel Islands and in Baja California from near El Rosario south to the Vizcaíno Peninsula The epithet honors William Nylander who published a monograph on the related genus Ramalina in 1870.
Vermilacinia tigrina is a fruticose lichen that grows on branches of shrubs and on earth among cactus and shrubs in the fog regions along the Pacific Coast of North America and South America; in North America found in the Channel Islands and near San Diego, California, and in central and southern Baja California; and in South America from Peru to Chile. The epithet is in reference to the irregular black spots or bands on the thallus branches.
Vermilacinia zebrina is a fruticose lichen that grows on bark of trees and shrubs, occasionally on rocks, in the fog regions along the Pacific Coast of North America, from Puget Sound in northern Washington to near El Rosario in Baja California. The epithet, zebrina, is in reference to the black transverse bands on the thallus branches; however, the species is interpreted to include thalli without black bands.
Niebla limicola is a fruticose lichen that grows on barren mud flats and on sand among salt scrub along the Pacific Coast of the Vizcaíno Desert, of Baja California from San Vicente Canyon to Scammon’s Lagoon. The epithet, limicola is in reference to the thallus growing on barren (alkali) soil.
Niebla marinii is a fruticose lichen that grows on lava along the Pacific Coast of Baja California from near San Fernando Canyon south to Morro Santo Domingo. The epithet, marinii, is in honor of a field assistant, Richard Marin, who accompanied the author on lichen-collecting expeditions to Baja California during 1985–1996, while he also assisted in the gathering of samples of flowering plants for cancer research.
