The cap is blue-green then greenish ochre-yellow, convex then flattened, often with an obtuse umbo; its margin is inrolled for a long time, with short-lived and scarce white flakes. The cap surface is covered with short-lasting flaky scales at the margin, viscid, sticky when dry. The stem is concolorous with cap, with white erect scale below the ring zone, and often with white mycelial strands at its base, with a membranous ring, not well formed and short lived. The flesh is whitish (cap) to blue-green (stem base), unchanging; its taste is faint, mild; the odour is faint; its texture is fibrous. The gills are reddish cream-ochre then chocolate brown, without a grey tinge and without a white edge, adnate to emarginate, crowded . The spore print is purple brown. This species is saprophytic. It grows on the ground, in parks, gardens, pathsides or roadsides, on a rather rich soil, often with stinging nettles. The fruiting period takes place from July to November.
Distinctive features : blueish viscid cap, with whitish short-lived cottony scales at the margin; stem with a ring zone, covered with whitish cottony scales on a blue-green background below; gills without a white edge; in parks, gardens, rich soils Stropharia cyanea is quite rare and localised in the forest of Rambouillet, and is occasional, more generally speaking . | ||
