Kuettlingeria furax
species of lichen
Kuettlingeria furax is a species of lichenicolous (lichen-dwelling) crustose lichen in the family Teloschistaceae. It grows as a parasite on other lichens in the genus Aspicilia that are found on silica-rich rock surfaces. Originally described in 1983 as Caloplaca furax from specimens found in southeastern Spain, it forms small, circular patches of deep brownish-grey colour with lobed edges.
Taxonomy
It was first formally described as a new species in 1983 by José María Egea Fernández and Xavier Llimona; they classified it in the genus Caloplaca. The type specimen was discovered in the eastern part of the Sierra Morena mountains in Albacete, Spain, growing parasitically on lichens in the genus Aspicilia found on silica-rich surfaces. The species name furax comes from Latin, meaning 'inclined to steal', alluding to its parasitic nature. It was collected in the Sierra del Relumbrar growing on metamorphic schist at an elevation of 830 m in a sparse holm oak woodland habitat.
Kuettlingeria furax appears as small, circular patches that are a deep brownish-grey colour. It has a somewhat lobed edge, and its reproductive structures (apothecia), quickly lose their thalline margin. The authors compared it to Caloplaca conglomerata, but noted the distinctness of its spores, which are broader and have a bulged middle.

Why this record matters
“Kuettlingeria furax” is worth following because a concise public description often conceals a longer documentary argument. Here, Kuettlingeria, furax and species provides the most credible route into that argument.
The date and method of observation matter as much as the stated conclusion, especially where classification or consensus has changed. The source revision retrieved here is dated Jun 26, 2025. The linked authority identifier is Q124473626. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1983.
Scientific names, classifications and consensus can change while older terminology persists in catalogues and historical literature. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
