Entoloma murrayi

Entoloma murrayi, commonly known as the yellow unicorn Entoloma or the unicorn pinkgill, is a species of fungus in the Entolomataceae family. It was first described from New England in 1859. The fungus produces yellow mushrooms that have a characteristic sharp umbo on the top of a conical cap. Other similar species can be distinguished from E. murrayi by differences in color, morphology, or microscopic characteristics. The species is found throughout the Americas and in southeast Asia, growing on the ground in wet coniferous and deciduous forests. The mushroom is inedible and may be poisonous. ...read more on Wikipedia.
