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 1¼to 2¾ long, to 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.

Occurrence

 
 

Infrequent

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.

Glossary

Pellicle

A thin, outer, gelatinous membrane on the surface of the cap of a mushroom.

 

Saprobic

Obtaining nutrients from non-living organic matter, such as decaying plant or animal 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 stem, and a volva at the base of the stem.

What is Rhodotus?
A report all about Rhodotus for homework/assignment

Rhodotus is a genus in the Physalacriaceae family of fungi. It is a monotypic genus and consists of the single mushroom species Rhodotus palmatus, known in the vernacular as the netted Rhodotus, the rosy veincap, or the wrinkled peach. This uncommon species has a circumboreal distribution, and has been collected in eastern North America, northern Africa, Europe, and Asia; declining populations in Europe have led to its appearance in over half of the European fungal Red Lists of threatened species. Typically found growing on the stumps and logs of rotting hardwoods, mature specimens may usually be identified by the pinkish color and the distinctive ridged and veined surface of their rubbery caps; variations in the color and quantity of light received during development lead to variations in the size, shape, and cap color of fruit bodies.

10 Creepy Plants And Fungi That Look Like Human Body Parts, despite what many might think, 10 Creepy Plants And Fungi That Look Like Human Body Parts is well known across hundreds of nations all over the world. 10 Creepy Plants And Fungi That Look Like Human Body Parts has been around for several centuries and has a very important meaning in the lives of many. It would be safe to assume that 10 Creepy Plants And Fungi That Look Like Human Body Parts is going to be around for a long time and have an enormous impact on the lives of many people.

#10 Bleeding Tooth Fungus
The hood of Hydnellum pecki comes in various shapes, and when it oozes a red, sticky substance, it could easily be mistaken for a bloody tooth dropped on the ground.

#9 Doll’s Eye
We’ve already documented how deadly Actaea pachypoda is, but its white oblong berries are the truly bizarre part of the plant. The berries sit at the end of red stalks similar to the eyes of Spongebob Squarepants’s boss, Mr. Krabs. The sinister-looking berries are a warning.

#8 Girdled Dapperling
Several different mushrooms have caps that look strikingly like human nipples. Many of these belong to the Lepiota genus. Lepiota boudieri‘s flesh-white cap gradually darkens from ochre to dark brown in the center. The surface appears almost smooth like skin. Covering the surface are thin, brown hairs.

#7 Hooker’s Lips
Psychotria elata is a tree found in the tropical rain forests of Central and South America (Panama, Costa Rica, Colombia, and Ecuador). From December through March, bright red bracts—specialized leaves—look like puckered lips smeared with lipstick. The ruby color entices pollinators like hummingbirds and butterflies. As the bracts open, they reveal small, star-shaped blooms and oval berries.

#6 False Morels
For many American mushroom hunters, the morel (Morchella) is the beluga caviar of the fungus world. It’s so popular that morels are sold for a least $20 per pound while in season. The drawback is that inexperienced hunters do not know the difference between real and false morels, and the latter are highly toxic. About 20 percent of mushroom-related deaths occur after the person ingests a false morel. There are several species of false morels, and some are less toxic than others. Less toxic varieties are considered delicacies in Nordic countries, where people boil and rinse the morels several times.

#5 Wrinkled Peach Mushroom
The cap of the wrinkled peach takes on various shapes and colors depending on to the quality and quantity of light it receives in its juvenile stages. Also known as the netted rhodotus and the rosy veincap, the wrinkled peach can look strikingly like a human heart, a stomach, or even a spongy lung. The surface of the cap is gelatinous and has white ridges or veins with reticulated deep grooves, looking like an internal organ’s vascular system. Beneath the surface, the flesh is firm.

#4 Snapdragon Seed Pod
Antirrhinum majus is an annual flower with dragon-like jaws that snap when the sides are squeezed. It’s believed that the snapdragon was originally a wildflower in Spain and Italy, and it has several legends associated with it. One of them is that if a person conceals the flower on their person or in a room, they will appear fascinating to other people. Another legend has it that any house with snapdragons growing in its flower bed will be free of curses and witchcraft.

#3 Wood Ear
Also called the tree ear or the jelly ear, Auricularia auricula has jelly-like flesh and a cupped, reddish-brown, ear-shaped body. It sports tiny, very fine hairs, and the surface is irregularly veined. They usually grow in groups on rotting or living trees. It has a similar shape to the cup fungus, but the Auricularia auricula is rubbery, not brittle.

#2 Purple Jellydisc Fungus
When the jelly-like Ascocoryne sarcoides first grows on a dead deciduous log, it appears as spherical lobes. Later, it flattens into a saucer shape.

#1 Devil’s Fingers Mushroom
Clathrus archeri, better known as devil’s fingers or octopus stinkhorn, is a truly creepy mushroom. In its mature form, it has four to eight fingers as red as a fire engine with black spheres that resemble suction cups on an octopus’s tentacles.
