Variospora Cancarixiticola
''Variospora cancarixiticola'' is a species of saxicolous lichen, 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 species description, formally described in 2000 as a species of ''Caloplaca'' by Pere Navarro-Rosinés, José Egea, and Xavier Llimona. The type (biology), type specimen was collected from the Sierra de las Cabras between Agramón and Cancárix (province Albacete, Castilla–La Mancha), at an altitude of . 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 (biology)#type locality, type locality. The botanical name, species epithet ''cancarixiticola'' refers to the unique substrate (biology), substrate. The authors noted its similarity to ''Caloplaca aurea'', and considered it to b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Saxicolous Lichen
A saxicolous lichen is a lichen that grows on rock. The prefix "sax" from the Latin means "rock" or "stone". Characteristics Saxicolous lichens exhibit very slow growth rates. They may develop on rock substrates for long periods of time, given the absence of external disturbances. The importance of the mineral composition of the rock substrate, as well as the elemental geochemistry Geochemistry is the science that uses the tools and principles of chemistry to explain the mechanisms behind major geological systems such as the Earth's crust and its oceans. The realm of geochemistry extends beyond the Earth, encompassing the e ... is also important to the distribution of saxicolous lichens, but the relationship between the substrate influence on lichens, either chemical or textural, is still obscure. Communities of saxicolous lichens are often species-rich in terms of number. References Lichenology {{lichen-stub ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
