Armillaria mellea (Vahl.:Fr.) P. Kumm. |
The cap is dark yellowish, honey to brown, hemispherical, then conical, expanded to depressed, with an umbo more or less marked; its margin is inrolled, then wavy and striate. The cap surface is covered with dark fibrillose scales especially towards centre, ultimately disappearing, not viscid nor sticky. The stem is beige yellowish, flexible, thin, turning black towards base, with a membranous white or yellow sheathing ring. The flesh is white, unchanging; its taste is bitter to acidic; the odour is faint, not very pleasant: acid, mushroomy, or of camembert cheese; its texture is fibrous. The gills are white to yellowish, stained with brown, adnate, crowded (nb of gills per 90° ~ 22 ). The spore print is white. This species is parasitic or saprophytic. It grows on wood (also on the ground, on buried wood), coming in dense tufts, in broad-leaved woods (more frequently) but also with conifers, in parks, gardens, with oak, willow, fir, larch, blackberry bush. The fruiting period takes place from June to December.
