Stellarangia elegantissima, the showy Namib firedot, is a species of saxicolous (rock-dwelling), crustose lichen in the family Teloschistaceae.
Having been shuffled to various genera in its taxonomic history, it was finally placed in genus Stellarangia in 2013 by Patrik Frödén and colleagues, following a molecular phylogenetics-based restructuring of the family Teloschistaceae.
This finding suggested that Nylander's description likely included a mixed collection predominantly of C. namibensis but also contained elements of C. elegantissima.
The provisions of Article 69 of the International Code of Nomenclature for algae, fungi, and plants, which would call for the rejection of a name if widely used for a taxon not including its type, were deemed inapplicable.
[4] In their 2024 popular work on lichens, Robert Lücking and Toby Spribille gave the species a vernacular name reflecting its striking appearance: the "showy Namib firedot".
The lichen's colour ranges from scarlet and orange-red to pale orange, with larger specimens typically showing lighter pigmentation at the margins.
The medulla, measuring 200 to 250 μm in thickness, is made of more lax hyphae, often containing numerous small granules that are fluorescent under interference contrast microscopy.
