Lecanora albellula
species of fungus
Lecanora albellula is a species of crustose lichen in the family Lecanoraceae. It grows tightly attached to the bark and wood of trees in both coniferous and mixed forests. First described in 1866 by the Finnish lichenologist William Nylander from material collected in Russian Lapland, it is widely distributed across Asia, Europe, and North America. The species is easily recognised by its pale, finely granular thallus—which can appear somewhat wart-like—and its small, round, light brick-coloured apothecia. Its name, referring to its whitish appearance, is based on traditional morphological observations used to distinguish it from similar species.
Research has refined the understanding of L. albellula through both modern genetic studies and detailed chemical analyses. These studies have clarified its placement within a well-defined clade of related lichens and revealed that some North American specimens previously identified as this species actually represent a closely related taxon, provisionally known as "Lecanora sp. D". Lecanora albellula produces characteristic secondary metabolites, notably isousnic acid, which, together with its distinctive anatomical and reproductive features, aids in distinguishing it from its congeners. Its occurrence on various tree barks and wood, particularly in temperate to subalpine regions, highlights its specific ecological requirements and the ongoing need for careful taxonomic verification.
The public source identifies “Lecanora albellula” as species of fungus. This brief keeps that definition visible, then builds a research path around Lecanora, albellula and species.
Why this record matters
A short description can identify a subject without explaining its stakes. For “Lecanora albellula”, the useful work is to connect “species of fungus” to the records capable of establishing context and consequence.
Stable identifiers, scientific names and standards terminology offer the best bridge between this overview and specialist evidence. The source revision retrieved here is dated Oct 23, 2025. The linked authority identifier is Q10555640. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1866.
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.
