Description |
Wrinkled Peach is a small to medium-sized, easily recognized but infrequently found gill mushroom. It is found scattered or in small groups on fallen, rotting hardwoods, especially on elm but occasionally also on basswood and maple. It is saprobic, getting its nutrients from well-decayed wood. The stalk (stipe) is 1¼″to 2¾″ long, ⅜″ to ⅝″ in diameter, solid, tough, dry, and slightly hairy. It is white to pinkish, the color determined by the amount and color of light it receives. It is often curved due to its appearance on the side of a fallen log. It is attached to the bottom of the cap centrally, slightly off-center, or almost laterally. It sometimes exudes red or orange sap. There are no remnants of a universal veil clinging to the stalk. The cap is ¾″ to 4″ in diameter, thick, and tough. It is pink and convex at first. As it ages it flattens out and becomes salmon, peach-colored, pink, or red. Like the stipe, the color is determined by the amount and color of light it receives. The margin is curved under. The skin in the upper surface (pellicle) is gelatinous and sometimes slimy to the touch. It is usually, but not always, conspicuously wrinkled with a network of whitish, cross-linked ridges. The presence of wrinkles is indicative of alternating wet and dry conditions. In an always wet environment, the surface will be smooth, puffy, and gelatinous. The pellicle peels off easily and completely. The flesh is pinkish, firm, and rubbery. It is considered inedible due to its bitter taste, but at least one source (Roger’s Mushrooms) lists the taste as mild. The gills are thick, closely spaced, and broadly attached to the stipe. They are similar in color to, but slightly paler than, the cap. The spore print is pinkish. |

Taxonomic Status & Future Revision
This species was long cataloged in North American field guides and regional databases as Rhodotus palmatus (or R. palmatus var. subpalmatus). Recent genetic analysis of Midwestern North American collections of Rhodotus showed that they are phylogenetically divergent from the European species. The resulting publication (Birkebak et al., 2026) formally recombined Montagne’s original species epithet (reticeps) under Rhodotus as Rhodotus reticeps to represent the distinct North American taxon.

Glossary
Pellicle
A thin, outer, gelatinous membrane on the surface of the cap of a mushroom.
Saprobic
A term often used for saprotrophic fungi. Referring to fungi that obtain their nutrients from decayed organic matter.
Stipe
A supporting stalk-like structure lacking vascular tissue: in fungi, the stalk supporting the mushroom cap; in ferns, the stalk connecting the blade to the rhizome; in flowering plants, the stalk connecting the flower’s ovary to the receptacle; in orchids; the band connecting the pollina with the viscidium.
Universal veil
An egg-like structure that envelopes all or most of a developing gill mushroom. Remnants of the universal veil sometimes visible on a mature mushroom are patchy warts on the cap, a ring on the stalk, and a volva at the base of the stalk.
Increasing
Before the middle of the twentieth century this mushroom was rare in North America. With the advance of Dutch elm disease, the number of dead elms has greatly increased, as has the population of this mushroom.
