Violet agaric, collected and examined
Cortinarius or Laccaria Genus
Angles captured. The most informative of the six. Five in-situ frames, then four with a fruitbody lifted and turned to show the gills and cap face directly.
Morphology
Cap 4–5 cm, lilac-violet fading paler toward the margin, dry and silky. Gills close, thin, and pinkish-brown to dull violet — the colour of a rusty spore deposit settling on a violet gill face. Stipe pale lilac, fibrillose, tapering slightly, base whitish.
Habitat & substrate
Oak leaf litter on level ground among low evergreen groundcover.
Lookalikes & what rules them out
Two genera stay in play. Laccaria amethystina and L. ochropurpurea have thick, widely spaced, waxy gills; Cortinarius has thinner, closer gills and a rusty spore print. Frames #4233, #4234 and #4243 show gills that are close and thin, with a distinctly pinkish-brown cast suggesting a rusty deposit — which points to Cortinarius. The blewit (Collybia nuda, long Lepista nuda; pale pinkish print) and Laccaria ochropurpurea are both common violet lookalikes here and stay on the list until a print exists.
To confirm this identification
A print from this collection settles this collection. The violet entries span four sites and three months; treating them as one species is exactly the assumption a print exists to test. Rusty brown = Cortinarius, white = Laccaria, pale pink = blewit.
Notes
Picking one up was the right call — the gill colour visible here is the single strongest piece of evidence in the violet group, and it favours Cortinarius.
