Vermilacinia robusta is an olive-green fruticose lichen that occurs on rocks near ocean mist along the foggy Pacific Coast of southern California to northern Baja California and offshore islands. [1] The epithet, robusta, was probably adopted in recognizing a more robust form of V. comboides, originally described as a variety of Ramalina combeoides by Reginald Heber Howe, Jr. in 1913.

Distinguishing features

Vermilainia robusta is classified in the subgenus Vermilacinia in which it is easily recognized by its relatively small number basal tubular branches, generally 5–10 in number, often inflated and connected to a basal holdfast. Deflated forms can be difficult to distinguish from other related species, but generally recognized by the simple branches that are relatively broad to their short length, not more than 4 cm long, up to 6 mm in diameter. Lichen substances are typical of the subgenus: T3, zeorin, and (-)-16 α-hydroxykaurane, occasionally with salazinic acid. [1]

Taxonomic history

The species was first recognized as a variety of Ramalina combeoides by Reginald Heber Howe, Jr. in 1913; [2] William Nylander had described the species in 1870. [3] Phillip Rundel and Peter Bowler elevated it to species status in 1978 when they renamed species in the illegitimate genus Desmazieria. [4] to Niebla [5] The species was transferred to Vermilacinia when described in 1995, distinguished by its cortical morphology, lack of chondroid strands in the medulla, and by its lichen metabolites, notably (-)-16 α-hydroxykaurane. [6] Peter Bowler and Janet Marsh, however, in 2004 retained the species in Niebla. [7]

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.

<i>Niebla</i> (lichen) Genus of lichen

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.

<i>Niebla homalea</i> Species of lichen

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.

<i>Vermilacinia procera</i> Species of lichen

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 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 tuberculata is a fruticose lichen known only from Morro Bay along the Pacific Coast of California The epithet tuberculata is a reference to the tuberculate surface of the lichen.

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 is in honor of 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 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 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.
