This attractive and distinctive mushroom can occasionally be found growing on dead wood in Europe and North Africa. The underside of the cap is typical of the genus Pluteus - the gills are pale, soon becoming pink when the spores ripen. But the upper surface is a bright tawny or olivaceous yellow. The species name leoninus (meaning leonine) refers to this cap colour.
Description
- The golden to olive-yellow convex cap is 3-7 cm in diameter, is hygrophanous, and usually has a grooved edge. The darker central disc has a slight velvety tomentum.
- The gills are yellowish at first, then salmon pink (the colour of the spore powder).
- The stipe is up to about 7 cm, often striate, being white to cream, and often darker near the base.
- The mushroom grows on stumps and wood debris of broad-leaved trees and sometimes of conifers.
- At the microscopic level, the filamentous cap cuticle is a trichoderm. The gills have scanty bladder-shaped pleurocystidia, and abundant fusiform cheilocystidia. The spores are smooth, almost globular, approx. 7×6μ.
