Angles captured. Twelve frames: several fine low profiles of one large fruitbody, two clean gill views, and wide shots showing many caps scattered across the slope with a hand for scale.

Morphology

The largest of the six populations — a dozen or more fruitbodies visible across one hillside. Mature cap 5–7 cm, expanding to plane with a low umbo, pale silvery-lilac with a warmer buff centre. Gills violet-grey, close, thin, adnexed. Stipe 6–8 cm, white-lilac, fibrillose.

Habitat & substrate

Oak litter on a slope beneath Rhododendron and wintergreen, near a fallen log. Widely gregarious rather than clustered.

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.

Notes

The scale here is the point: this many fruitbodies of one species across a single slope indicates one large, well-established mycelium.
