Niebla effusa is a fruticose lichen that grows on gravelly soil along the foggy Pacific Coast of Baja California from near Punta Colonet south to near Punta Rosarito. [1] The epithet, effusa is in reference to the thallus spreading widely along the surface.
Niebla effusa is recognized by the thallus divided into a tangled mat of irregularly cylindrical-prismatic branches without a central connection at base–to as much as 1 meter in diameter, weighing more than 1 kg—and by the ultimate parts of the primary branches becoming hooked, dilated, and fringed from which there are many erect branchlets. [1] Black dot-like pycnidia are usually infrequent and scattered along the branch margins and cortical ridges. A key lichen substance is salazinic acid, which may be accompanied by an unknown, possibly scabrosin derivative. Triterpenes are absent as in all species in the depsidone species group. [1]
Niebla effusa was first recognized as a distinct species from a related species, Niebla josecuervoi, before it was described as a result of collecting lichen samples near Cerro Solo in northern Baja California for a biodiversity screening of lichens—in the search of new drugs by the National Cancer Institute (NCI) Natural Products Branch to treat HIV. It was distinguished by its habit of growing on the ground in contrast to N. josecuervoi growing on a vertical face of a large bounder with Niebla eburnea and Vermilacinia procera . A sample of 68 grams of Niebla josecuervoi was submitted to the NCI on 8 February 1986, but not of N. effusa. [2] based on its thalli with a holdfast.
Niebla effusa seems to have been recognized earlier as a terricolous species that forms extensive mats “on beach terrace deposits atop coastal bluffs south of El Rosario and beyond, often in densities great enough to color the landscape yellow-green," based on study of lichen communities further north around Bahía de San Quintín. [3] However, the terricolous species around Bahía de San Quintín is largely N. arenaria, whereas further south N. effusa is common. [1] These species were recognized as Niebla pulchribarbara , which the type reportedly contained protocetraric acid, a rare chemotype for the genus not found south of Bahía de San Quintín. [1] Another terricolous species, containing sekikaic acid, occurred at Bahía de San Quintín, [3] described as Niebla palmeri . [1]
Niebla effusa is a characteristic lichen of the transition zone from the California Floristic Province to the Northern Vizcaíno Desert. [1] The species has been included under a broader concept, Niebla josecuervoi , one that also includes Niebla pulchribarbara and many other species of Niebla [4]
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.
Vermilacinia cedrosensis is a species of pale fruticose lichen that is endemic to Baja California, Mexico.
Vermilacinia ceruchoides is a fruticose lichen found on rock faces of cliffs or boulders, sometimes growing among mosses, usually near the ocean, ranging in distribution from Marin County, California to San Vicente on the northern peninsula of Baja California, and in the Channel Islands.
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
Niebla arenaria is a fruticose lichen that grows along the Pacific Coast of North America in the fog regions of the northern peninsula of Baja California from near Colonet south to Morro Santo Domingo. The epithet, arenaria, is in regard to the species growing on sand.
Niebla brachyura is a rare fruticose lichen that grows along the Pacific Coast of North America in the fog regions of the northern peninsula of Baja California in the Northern Vizcaíno Desert. The epithet, brachyura, is in regard to the species resembling a crab lying on its back with its leg appendages pointing up.
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 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 homaleoides is a fruticose lichen that grows on rocks within a narrow region of the foggy Pacific Coast of Baja California in the Northern Vizcaíno Desert, Arroyo Sauces, Punta Cono and ridges south of Punta Negra. The epithet, homaleoides is in reference to the similarity to Niebla homalea.
Niebla josecuervoi is a fruticose lichen that grows on rock, stony soil and sand along the Pacific Coast of northern Baja California from near Misión San Vicente Ferrer to Punta Santa Rosalilillita. The epithet, josecuervoi is in honor of a field assistant, “Jose Cuervo”.
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 lobulata is a fruticose lichen that grows on rocks in the fog regions along the Pacific Coast of Baja California, from Bahía de San Quintín to Vizcaíno Peninsula and offshore islands, Isla San Martín, and Guadalupe Island. The epithet, lobulata is in reference to the lobed margins of the thallus branches.
Niebla podetiaforma is a fruticose lichen that grows frequently on small stones in fog regions along the Pacific Coast of Baja California from San Vicente Canyon to Morro Santo Domingo. The epithet, podetiaforma is in reference to a primary inflated branch of the thallus that resembles a podetium, a common feature in the lichen genus Cladonia.
Niebla pulchribarbara is a rare fruticose lichen that occurs on sandy beaches or gravelly soil along the Pacific Coast, at San Antonio del Mar and at Bahía de San Quintín, Baja California. The epithet, pulchribarbara, is in reference to the strikingly beautiful lichen mat formed by the 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 spatulata is a fruticose lichen that grows on small rocks along the foggy Pacific Coast of central Baja California in the Vizcaíno Desert. The epithet, spatulata is in reference to the flattened branches of the thallus, in contrast to another similar species, Niebla flabellata.
Niebla suffnessii is a fruticose lichen that grows on rocks along the foggy Pacific Coast of North America within the Vizcaíno Desert region of Baja California. The epithet, suffnessii, is in honor of Matthew Suffness who was Chief of the Natural Products Branch in the National Cancer Institute during the late 1970s to mid 1980s, and later a coordinator of the National Institutes of Health (NIH) contracts for the drug discovery groups, and who also encouraged the screening of lichens and bryophytes in the search for new anticancer drugs.
