Description
 
 

Orange Peel Fungus is a conspicuous, widespread, and very common cup fungus.

It is found in summer and fall, usually on bare, often clayey soil, on roadsides, trails, and other disturbed areas. It is sometimes found on moss or grass. It may be scattered but usually grows in clusters of caps that sometimes fuse together.

There is no stalk.

The cap is round and cup-shaped when it first emerges, becoming saucer-shaped and flat or wavy when mature. When clustered, the caps are often irregularly shaped, contorted. Mature caps may be ¾ to 4 in diameter. The upper side is bright orange and hairless, fading to yellowish-orange with age. The underside is paler and densely covered with minute, white, downy hairs when young, becoming hairless as it ages. The margin is often wavy or lobed. There is no fringe of dark hairs on the margin.

The flesh is thin and brittle. It is edible but bland, fragile, and insubstantial.
