Description
 
 

Orange-gilled Waxy Cap is a medium-sized, easily identified, wax cap mushroom. It is widespread in North America but not common in the Midwest and northeast. It grows on the ground in humus, sometimes on very rotten wood, in coniferous, deciduous, and mixed forests. It may be found singly, scattered, or in small groups.

The cap is to 2 in diameter. When it first appears it is broadly cone-shaped or convex and bright orange. As it ages it flattens out at the margins but retains a broad, low bump in the center (umbonate). Mature specimens are almost flat, sometimes with upturned margins. As they age they fade to yellow. The cap is smooth and hairless. It appears watery when wet and opaque when dry. It may be tacky but is not slimy.

The flesh is thin, fragile, waxy, and the same color as the cap.

The stalk is 1½ to 4¾ long, to ¼ thick, and more or less equal from top to bottom. It is hollow, smooth, fragile, and often curved. It may be orange, pale orange, orangish yellow, yellow, or buff.

There is no universal veil.

The gills are broad, thick, well spaced, soft, waxy, and orange. They retain their orange color even long after the cap has faded to yellow. They are broadly attached (adnate) and may very slightly run down the stalk (decurrent), but sometimes they pull away from the stalk (free). The sport print is white.

It is edible but insubstantial and watery.

Orange-gilled Waxy Cap mushroom was originally classified as Hygrophorus marginatus. In 1916 it was transferred to Hygrocybe marginata, in 1958 to Humidicutis marginata. All three names are in current use in print and online sources.

Three varieties are recognized; var. marginata, with an orange cap, described here; var. concolor, with a yellow cap, more common in the northeast; and var. olivacea, with a olive-colored cap, more common in the west.

Glossary

Umbonate

On mushrooms, having a distinct, raised, knob-like projection in the center of the cap.
