Russula ochroleuca
species of fungus

Russula ochroleuca is a member of the genus Russula. A group that have become known as brittlegills. It has been commonly known as the common yellow russula for some years, and latterly the ochre brittlegill. It is widespread, and common in mixed woodland.
Taxonomy
Russula ochroleuca was first noted and named as a species of Agaricus by the pioneering South African mycologist Christian Hendrik Persoon in 1801.
Description
The cap is dull yellow and 5–12 cm (2–4.5 in) wide, initially convex, later flat, or slightly depressed. The cap margin becomes furrowed when mature, and it is two-thirds peeling. The gills are white to greyish white, and are adnexed. The stipe is 3–7 cm (1–3 in) long, 1–2 cm (0.5–1 in) wide, cylindrical, white or later greyish. The taste is mild to moderately hot.
Begin with the source’s own compact description: “Russula ochroleuca” is species of fungus. The dossier treats that line as a proposition to test through Russula, ochroleuca and species, not as a finished interpretation.
Why this record matters
The phrase “species of fungus” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
Datasets, specimens, observations and peer-reviewed methods provide the appropriate test for the technical claims summarized here. The source revision retrieved here is dated Jul 21, 2026. The linked authority identifier is Q206438. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1801.
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.
How to read it
