Gyalolechia fulgens
species of Lecanoromycetes
Gyalolechia fulgens, the scrambled egg lichen, is a species of terricolous (ground-dwelling), squamulose lichen in the family Teloschistaceae. The lichen comprises overlapping, slightly pruinose lemon-yellow scales with a lobed margin. It grows on highly calcareous substrates such as chalk, limestone and shell sand, often in association with the moss species Trichostomum crispulum.
Taxonomy
The species was first formally described by the Swedish taxonomist Olof Swartz in 1784, as Lichen fulgens. In its long taxonomic history, it has been proposed for inclusion in several genera, including Biatora, Caloplaca, Fulgensia, and Lecanora, among others. It was transferred to the genus Gyalolechia in 2013 by Ulrik Søchting and colleagues, as part of a molecular phylogenetics-based restructuring of the Teloschistaceae. Its common name, "scrambled egg lichen'", alludes to its overlapping yellow scales with white margins. The species epithet fulgens is Latin for "shining". Another vernacular name is "yellow ground lichen".
Description
Gyalolechia fulgens has a distinctive appearance and colouration, which makes it readily identifiable.
“Gyalolechia fulgens” enters the record as species of Lecanoromycetes. Crown Archives preserves that source wording while asking what Gyalolechia, fulgens and species can confirm, complicate or overturn.
Why this record matters
“Gyalolechia fulgens” is worth following because a concise public description often conceals a longer documentary argument. Here, Gyalolechia, fulgens and species provides the most credible route into that argument.
Stable identifiers, scientific names and standards terminology offer the best bridge between this overview and specialist evidence. The source revision retrieved here is dated Jul 17, 2025. The linked authority identifier is Q26260500. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1784 and 2013.
Current terminology should not be projected backward without checking the classification used when the underlying evidence was created. 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.
