Reichlingia (lichen)

Reichlingia is a genus of lichenized fungi belonging to the family Teloschistaceae. These lichens are typically crustose, meaning they form a crust-like layer tightly adhered to their substrate. Reichlingia species are characterized by their bright orange to yellow color, attributed to the presence of parietin and other anthraquinone pigments in their tissues.

The genus is relatively small, encompassing a limited number of species. Key distinguishing features used in their identification include the morphology of the apothecia (fruiting bodies), the structure of the ascospores, and the chemical composition of the thallus.

Reichlingia lichens are primarily found growing on calcareous substrates, such as limestone and mortar, in open and well-lit environments. They have a distribution that includes parts of Europe.

The taxonomy of Reichlingia has undergone some revisions, reflecting ongoing research into the phylogenetic relationships within the Teloschistaceae family. Molecular studies have played a significant role in clarifying the placement of Reichlingia and its relationship to other related lichen genera.
