Cortinarius erythraeus
species of fungus

Cortinarius erythraeus, sometimes known as the Jammie Dodger, is a basidiomycete fungus of the genus Cortinarius native to Australia.
English botanist Miles Joseph Berkeley described this species as a "blood red" mushroom, "clothed with a thick gelatinous coat" in 1845, from the writings and specimens of James Drummond, from the vicinity of the Swan River Colony in Western Australia. The species name is derived from the Ancient Greek word erythros "red". John Burton Cleland described Cortinarius ruber in 1928 from a collection in Kinchina, South Australia. Later analysis indicated it was the same species as C. erythraeus.
The fruitbodies of this fungus have hemispherical to convex brick- to brown-red caps, with diameters up to 5 cm (2.0 in) and covered with a layer of slime. The cap centre may be depressed or raised (umbonate) with a boss. The cap margins are curved inwards and smooth. The gills on the cap underside have a subdecurrent attachment to the stipe. Initially light tan or clay-coloured, they deepen to rusty brown as the spores mature.

Why this record matters
“Cortinarius erythraeus” is worth following because a concise public description often conceals a longer documentary argument. Here, Cortinarius, erythraeus 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 Feb 1, 2026. The linked authority identifier is Q4036565. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1845 and 1928.
A general summary may omit uncertainty, sample limits or methodological disagreement that is explicit in the technical record. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
