Niebla dactylifera is a fruticose lichen that grows only on San Nicolas Island in the Channel Islands of California. The epithet, dactylifera, is in reference to the terminal finger-like branches. [1]
Niebla dactylifera is recognized by the thallus divided into tubular-prismatic branches that arise from a thick basal attachment area; the branches, which are not more than 3.0 cm high, become widened above similar to the palm of a hand from which develop many shorter finger like branches. The cortex is not more than 75 μm thick, in contrast to that of Niebla dissecta, 75–110 μm thick, a similar species that further differs by a more regularly branched thallus, one that is also broader at the base than above the base. Black dot-like pycnidia are infrequent and inconspicuous at tips of the ultimate branches. The key lichen substances is sekikaic acid, with accessory triterpenes. Pigmentation is weak near base of thallus, the cortex appearing brownish with blackish areas. [1]
Niebla dactylifera was recognized as a result of undertaking a taxonomic revision of the genus in regard towards development of a lichen flora of Baja California, beginning in 1986. A peer review of the manuscript in 1990 suggested that additional herbarium collections be studied, especially of Niebla collected in California and the Channel Islands. Additional specimens were studied through loans obtained by the U.S. National Herbarium (Smithsonian Institution) [2] from the University of Colorado at Boulder and from the Santa Barbara Museum of Natural History. Niebla dactylifera was discovered among the borrowed specimens of Niebla. [1]
Vermilacinia cedrosensis is a species of pale fruticose lichen that is endemic to Baja California, Mexico.
Vermilacinia polymorpha is a fruticose lichen infrequently found on Santa Catalina Island in the Channel Islands of California and along the mainland coast in Ventura and Orange counties. It has also been indicated to occur south into northwestern Baja California without reference to specimens to support its range extension, and shown to occur on the Vizcaíno Peninsula in central Baja California on a distribution map in a lichen flora, without reference to specimen data; however, specimen data from other sources indicate it does occur as far south as Punta Santa Rosalillita on the main peninsula of Baja California, and also reported from Guadalupe Island.
Vermilacinia rosei is a fruticose lichen known from two islands off the Pacific Coast of central Baja California, San Roque Island and Cedros Island. The epithet, rosei, is in honor of Joseph Nelson Rose who collected the lichen on San Roque Island, 15 March 1911, during the Albatross Expedition. His lichen specimens had been kept separate from the mounted and filed lichen collections in the herbarium at the Smithsonian Institution, Department of Botany, US) loose in brown standard herbarium paper, and were made available to Richard Spjut sometime after 1986 while he was undertaking a revision of the genus Niebla. The epithet was proposed by Albert William Herre who considered the lichen to be a new species but did not describe the species or publish the name. .
Niebla caespitosa is a fruticose lichen that grows along the fog regions of the Pacific Coast of North America from southern California, including the Channel Islands, to the Vizcaíno Peninsula of Baja California. The epithet, caespitosa, is in regard to the clustered thallus branches spreading widely from a central attachment or holdfast
Niebla dilatata is a fruticose lichen that grows on rocks on Guadalupe Island and the foggy coast of the Baja California peninsula. The epithet, dilatata, is in reference to the broadly expanded (dilated) lobes of the thallus.
Niebla disrupta is a fruticose lichen that grows on rocks along the foggy Pacific Coast of California, from Marin County to San Luis Obispo County, in the Channel Islands, and on Guadalupe Island in Baja California. The epithet, disrupta was given by William Nylander possibly in reference to the terminal vine-like branchlets exhibiting a disruption or slight change in the direction of growth where apothecia develop, or possibly to the branchlets that appear to break off.
Niebla dissecta is a fruticose lichen that grows on rocks along the Pacific coast of California, in San Mateo County and in the Channel Islands. The epithet dissecta is in reference to the thallus repeatedly divided into branches.
Niebla eburnea is a fruticose lichen that grows on rocks along the foggy Pacific Coast of North America, from Mendocino County in California south to near Punta Santa Rosalillita in Baja California, and also in the Channel Islands. The epithet, eburnea is in reference to the ivory like appearance of the cortex.
Niebla flabellata is a fruticose lichen that grows on rocks along the foggy Pacific Coast of Baja California in the Northern Vizcaíno Desert, from San Fernando Canyon to the northern shore of the Vizcaíno Peninsula west to Cedros Island. The epithet, flabellata is in reference to the flattened branches of the thallus.
Niebla flagelliforma is a fruticose lichen that grows on rocks along the foggy Pacific Coast of Baja California mostly in the Northern Vizcaíno Desert. The epithet, flagelliforma is in reference to the individual branches of the thallus shaped like a flagellum.
Niebla halei is a fruticose lichen that grows on rocks along the foggy Pacific Coast of northern California on San Bruno Mountain The epithet, halei is in honor of Mason Hale who encouraged taxonomic revision of the genus Niebla.
Niebla infundibula is a fruticose lichen that grows on rocks along the Pacific Coast in the Channel Islands of California and in Baja California on Guadalupe Island, and on the main peninsula in the southern region of the Northern Vizcaíno Desert on a ridge south of Punta Negra. The epithet, infundibula, is in reference to the funnel shape of the thallus branches.
Niebla isidiosa is a fruticose lichen known only from Guadalupe Island. The epithet, isidiosa is in reference to isidia (isidium) on the thallus.
Niebla juncosa is a fruticose lichen that grows on rock, stony soil and sand along the Pacific Coast of Baja California from Punta Banda to Morro Santo Dominogo. The epithet, juncosa is in reference to the thallus divided into rush-like branches, the stems of the flowering plant genus Juncus.
Niebla laminaria is a fruticose lichen that grows on rocks along the Pacific Coast of North America within the California Floristic Province, from Marin County, California south to Misión San Vicente Ferrer in Baja California, and in the Baja Channel Islands. The epithet, laminaria is in reference to the thallus divided into blade-like branches similar to a genus of brown algae, Laminaria.
Niebla ramosissima is a rare fruticose lichen that grows on soil on San Nicolas Island in the Channel Islands of California. The epithet, ramosissima, is in reference to the very much branched thallus.
Niebla siphonoloba is a fruticose lichen that grows on rocks along the foggy Pacific Coast of North America, in the Channel Islands, and from Bahía de San Quintín, Baja California to the Vizcaíno Peninsula. The epithet, siphonoloba is in reference to the pipe-like shape of the thallus branches.
Niebla sorocarpia is a fruticose lichen that grows on rocks along the foggy Pacific Coast of California in the Channel Islands and in Baja California in the Northern Vizcaíno Desert. The epithet, sorocarpia, is in reference to the terminal aggregate apothecia.
Niebla testudinaria is a fruticose lichen that grows on rocks along the foggy Pacific Coast of North America, from Marin County, California to just south of Tijuana in Baja California, in the Channel Islands in California, and Isla San Martín and Guadalupe Island in Baja California The epithet, testudinaria given by William Nylander in 1870, is probably in reference to the dilated branch with a reticulated surface, similar to a tortoise shell.
Niebla undulata is a fruticose lichen that grows on rocks in the fog zone along the Pacific Coast of Baja California in the Northern Vizcaíno Desert, and also in the Channel Islands. The epithet, undulata, is in reference to the wavy margins of the thallus.
