Variospora cancarixiticola is a species of saxicolous (rock-dwelling), crustose lichen in the family Teloschistaceae. It is found in southeastern Spain, where it grows on cancarixite, a volcanic rock known only to occur in that country.

Taxonomy

The lichen was first formally described in 2000 as a species of Caloplaca by Pere Navarro-Rosinés, José Egea, and Xavier Llimona. [2] The type specimen was collected from the Sierra de las Cabras between Agramón and Cancárix (province Albacete, Castilla–La Mancha), at an altitude of 671 m (2,201 ft). There, it was found growing on cancarixite, an alkaline igneous rock of the lamproite group found only in southeast Spain. The lichen is only known to occur at the type locality. The species epithet cancarixiticola refers to the unique substrate. The authors noted its similarity to Caloplaca aurea , and considered it to belong to the subgenus Gasparrinia of genus Caloplaca. [2]

The taxon was transferred to the newly circumscribed genus Variospora in 2013, as part of a molecular phylogenetics-directed reorganisation of the family Teloschistaceae. [3]

Description

Variospora cancarixiticola has a crustose thallus with a placodioid growth form, and forms yellowish-orange to reddish-orange rosettes up to 4 cm (1.6 in) in diameter. It produces roundish, zeorine apothecia (i.e., in which the proper exciple is enclosed in the thalline exciple) measuring 0.5–1.7 mm (0.02–0.07 in) in diameter that occur scattered on the thallus surface, or in groups of 2 to 5. Ascospores number eight per ascus, and are colourless, narrowly ellipsoid, and polarilocular (i.e. divided into two compartments), with typical dimensions of 16–22 by 4.5–6  μm. [2]

Teloschistaceae Family of lichen-forming fungi

The Teloschistaceae are a large family of mostly lichen-forming fungi belonging to the class Lecanoromycetes in the division Ascomycota. The family, estimated to contain over 1800 species, was extensively revised in 2013, including the creation or resurrection of 31 genera. It contains three subfamilies: Xanthorioideae, Caloplacoideae, and Teloschistoideae. A fourth subfamily, Brownlielloideae, proposed in 2015, has been shown to be part of the Teloschistoideae.

Neobrownliella brownlieae is a species of saxicolous (rock-dwelling), crustose lichen in the family Teloschistaceae. It is widely distributed in Australia.

Fulgogasparrea decipioides is a species of lichen in the family Teloschistaceae. It is found in Gangwon Province, South Korea. This species was originally described in 2011by Ulf Arup as a member of the large genus Caloplaca. The specific epithet decipioides refers to its similarity with Caloplaca decipiens. Arup and colleagues transferred it to genus Wetmoreana in 2013, before it was again transferred to Fulgogasparrea that same year, a genus in which it is the type species.

Cerothallia yorkensis is a species of crustose lichen in the family Teloschistaceae. Found in Australia, where it grows on limestone outcrops, it was described as new to science in 2011. The specific epithet yorkensis refers to the type locality, Yorke Peninsula. It was originally described as a member of the genus Caloplaca, but transferred to Cerothallia in 2013.
