Pluteus leoninus
Species of fungus
From Wikipedia, the free encyclopedia
Pluteus leoninus, commonly known as the lion pluteus[1] or lion shield, 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
This description is combined from several references.[2][3][4][5]
- 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, approximately 7×6 μm.
Many authorities consider Pluteus fayodii to be a synonym of P. leoninus,[6][3][7] but according to Species Fungorum, they are distinct.[8]
