Stropharia aeruginosa (Curtis:Fr.) Quél. |
The cap is blue-green to emerald green then yellowish, hemispherical then convex and ultimately flattened, often with an obtuse umbo; its margin is inrolled for a long time, with white flakes overhanging in the youth. The cap surface is covered with short-lasting white flakes, especailly towards the margin, viscid, sticky when dry, entirely peelable. The stem is white to greenish-blue, with white erect whitish scales on a blueish background under the ring, smooth above it, and often with white mycelial strands at its base, with a membranous, superior and spreading ring. The flesh is whitish (cap) to blue-green (stem base), unchanging; its taste is faint, sometimes slightly bitter; the odour is faint, of old barrel, radish or grassy; its texture is fibrous. The gills are white then purple grey then brown, with a white edge for a long time, adnate to emarginate, crowded (nb of gills per 90° ~ 28 ). The spore print is purple brown. This species is saprophytic. It grows on the ground, sometimes also on buried wood, in the woods, forest edges, parks and paths. The fruiting period takes place from June to December.
