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.
Cylindropuntia californica is a species of cholla cactus known by the common name snake cholla. It is primarily found in Baja California, Mexico and the southernmost part of California in the United States. It is characterized by a short, decumbent habit, yellow-green flowers, elongated stems, and short spines. It is mostly found in coastal sage scrub and coastal chaparral habitats, but two varieties in Baja California can be found in foothills and deserts. In California, variety californica is regarded as a rare and threatened plant, with a California Native Plant Society listing of 1B.1, in part due to its limited number of occurrences and threats from development. It formerly had a larger range due to the inclusion of Cylindropuntia bernardina within it as the variety parkeri.
Lichens of the Sierra Nevada have been little studied. A lichen is a composite organism consisting of a fungus and a photosynthetic partner growing together in a symbiotic relationship.
Candelariella aurella, the hidden goldspeck lichen or eggyolk lichen, is a yellow crustose lichen in the family Candelariaceae. It is commonly found on calcareous rock or wood or bark exposed to sunlight and which may have calcareous dust in areas with lime soils. The thallus is areolate with scattered small (0.1–0.3 mm), rounded to elongated yellow areolas. It has a global distribution and occurs on limestone and calcareous sandstone in the Sonoran Desert in Arizona, California, and Baja California. It occurs in Joshua Tree National Monument.
Candelariella antennaria, or the pussytoes eggyolk lichen, is a lichen commonly distributed in North America, and has been observed in South America, Asia, Australia, and Europe. It is characterized by its gray thallus and bright yellow apothecia, as well as its very small size.
Candelariella rubrisoli is a species of crustose lichen in the family Candelariaceae. It was described as new to science in 2019 by Dong Liu and Jae-Seoun Hur. The type was collected near Huagou Village, in Dongchuan District. Here it was found growing on Chinese white pine at an elevation of about 2,400 m (7,900 ft). The specific epithet rubrisoli refers to the red soil of the type locality. The lichen is characterized by the areolate to somewhat squamulose (scale-like) thallus. The thallus typically breaks and eventually dissolves into soredia. Calycin and pulvinic acid are the major secondary metabolites present in the lichen.
Candelariella flavosorediata is a species of lichen in the family Candelariaceae. Found in Réunion, it was described as a new species in 2021 by lichenologists Klaus Kalb and André Aptroot. The type was collected just below the summit of the Maïdo, at an elevation of about 2,100 m (6,900 ft). Here it was found growing on tree bark in scrub. The specific epithet flavosorediata refers to the yellow soredia that cover most of the lichen thallus.
Candelariella aggregata is a species of lichen in the family Candelariaceae. It is found in western North America, Mongolia, and Switzerland where it grows on mosses and plant debris.
Candelariella immarginata is a species of parasitic, saxicolous (rock-dwelling) lichen in the family Candelariaceae. Found in the United States, it was formally described as a new species in 2007 by Swedish lichenologist Martin Westberg. The type specimen was collected in the desert west of Grantsville, Utah at an elevation of 4,300 ft (1,300 m); here it was found growing on dry exposed quartzite. At the time of publication, it had also been found in another location in Utah, and two locations in Nevada; its general geographic range is the Great Basin in western North America. In 2015, it was recorded from the White Mountains of California. The species is lichenicolous on Aspicilia species and pyrenocarpous lichens. The specific epithet immarginata refers to the lack of a thalline margin on the apothecia. Secondary compounds that have been detected in the lichen include calycin, pulvic acid lactone, vulpinic acid, and pulvinic acid.
Candelariella deppeanae is a species of lichen in the family Candelariaceae. Found in southwestern North America, it was formally described as a new species in 2007 by Swedish lichenologist Martin Westberg. The type specimen was collected in the Chiricahua Mountains at an elevation of 1,750 m (5,740 ft). Here, in an oak forest, it was found growing on a decorticated (barkless) part of alligator juniper. Most collections of the lichen are from the wood or trunks of this juniper plant; the species epithet deppeanae alludes to this close relationship.
Candelariella corallizoides is a species of squamulose (scaley), saxicolous (rock-dwelling) lichen in the family Candelariaceae. Found in Mexico, it was formally described as a new species in 2007 by Swedish lichenologist Martin Westberg. The type specimen was collected from the north-facing cliffs of the Sierra Agua Verde at an elevation of 1,200 m (3,900 ft). Here, in open oak woodland with shrubs, it was found growing on siliceous rock. The lichen is known to occur in several localities in Baja California. The specific epithet corallizoides refers to the coralloid squamules of the thallus.
Candelariella efflorescens, commonly known as the powdery goldfleck lichen, is a species of lichen in the family Candelariaceae. Found in North America, it was formally described as a new species in 1978 by Richard C. Harris and William R. Buck. The type specimen was collected by the second author from Hog Island Point State Forest Campground ; here, at the edge of a swamp, it was found growing on Populus balsamifera. The lichen has a temperate eastern North American distribution. Although it occurs most frequently on bark, it has also occasionally been recorded growing on wood. Before its description as a new species, it had most often been confused with Candelariella xanthostigma, Candelariella concolor var. effusa, and Lepraria candelaris when well developed.
Candelaria pacifica is a widely distributed corticolous (bark-dwelling), leprose lichen. It was formally described as a species in 2011.
