This is a classic Gliophorus in the lilac–green complex: a medium‑sized, strongly glutinous, colour‑shifting forest waxgill with a distinctive lilac stipe apex, green‑blue pileus, and a gelatinised cheilocystidial thread forming a sterile gill edge.

Note: As with other Gliophorus, colour shifts arise from water‑soluble pigments, underlying less soluble pigments, and UV‑labile dyes. The green‑blue → blue‑ lilac transitions fading are consistent with pigment leaching in wet conditions and photodegradation in exposed basidiomes. This is independent of hygrophany.
Pileus: 15-45 mm diam., initially hemispherical, later plano‑convex; very old specimens broadly umbilicate. Colour deep green‑blue when fresh, fading to blue‑brown or greenish‑blue, typically darker at centre. Surface glutinous, glabrous, strongly hygrophanous; margin striate when moist.
Lamellae: broadly adnate to decurrent, distant, lilac‑blue to greenish-blue, fading with age. Gill edge distinctly sterile, bearing a gelatinised grey thread formed by densely interwoven cheilocystidia.
Stipe: 20-60 x 2-5 mm, cylindric, equal or slightly attenuated upwards, apex lilac; base yellowish to ochraceous. Entire stipe glutinous; hollow; single.
Context: deep lilac in upper stipe, becoming reddish on drying. Odour and taste not distinctive.
Odour/tast: Not recorded

These pink ones are rather interesting. It's possible that the lilac colouring is dominating the fruiting body.
