Lecanora solaris
species of lichen
Lecanora solaris is a species of saxicolous (rock-dwelling) crustose lichen in the family Lecanoraceae. Found in the Altai Mountains in Russia, the lichen was described as new to science in 2019 by Lydia Yakovchenko and Evgeny Davydov. The lichen is similar in general morphology to Lecanora somervellii, but can be distinguished from that species by its small, squamulose (scaly) to marginally lobate umbilicate thallus and the persistent margin of its apothecia. The species epithet makes reference to the bright yellow (solaris = "sunny") colour of the lichen.
Description
Lecanora solaris is a lichen characterized by a squamulose (scale-like) thallus that forms roughly circular patches up to 10–15 mm in diameter. The individual squamules measure 0.7–1.3–1.9 mm across, are crowded together, and appear moderately to strongly convex. Initially rounded, they soon become incised with irregular outlines, and sometimes develop a peltate (shield-like) form attached at a central point. The surface is distinctively bright yellow and shiny, initially smooth but becoming strongly rugose (wrinkled) with age. The thallus lacks vegetative propagules (structures for asexual reproduction), with its yellow colouration resulting from the presence of calycin and usnic acid.
Apothecia (fruiting bodies) are common and typically concentrated in the centre of the thallus.

Why this record matters
“Lecanora solaris” is worth following because a concise public description often conceals a longer documentary argument. Here, Lecanora, solaris and species provides the most credible route into that argument.
Datasets, specimens, observations and peer-reviewed methods provide the appropriate test for the technical claims summarized here. The source revision retrieved here is dated May 5, 2025. The linked authority identifier is Q106706282. None of the 0 selected statements returned an explicit reference. The first chronological checks are 2019.
A general summary may omit uncertainty, sample limits or methodological disagreement that is explicit in the technical record. 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.
