Top 20 Edible Mushrooms Popular in Boulder

1. Shaggy mane

The shaggy mane mushroom is commonly found in North American and European grasslands. Some peoples foraged for its young egg-shaped caps, but it has more recently been found to be a bioaccumulator of heavy metals, meaning it pulls toxic metals up from the soil where it grows. As a result, shaggy manes should not be eaten. The mushrooms usually appear in clusters or “fairy rings.”

2. Dryad's saddle

A familiar sight to spring morel hunters, dryad's saddle is noteworthy for its large size, striking scales, and watermelon-like smell. Similar to other mushrooms in the bracket fungi family, dryad's saddle can be used to make paper. Younger mushrooms are better suited for this purpose due to their smaller and more consistent fibers.

3. Fairy ring mushroom

Fairy ring mushrooms may dry out completely in the sun, but will “resurrect” during the next rain and regain their ability to make new spores. This is due to a sugar called trehalose which protects their cells. They appear in lawns and fields, sometimes in “fairy ring” configurations.

4. Shingled hedgehog

Shingled hedgehog(Sarcodon imbricatus) is often found in the company of fir trees, and it is therefore partial to mountainous or hilly regions. Endemic to Europe and North America, the species is prone to forming fairy rings. It fruits in early autumn.

5. Blue-staining slippery jack

If you come across a blue-staining slippery jack (Suillus tomentosus) in the wilderness, chances are you're adventuring through a conifer forest after heavy rain. True to the common name, the caps can stain your hands a brownish-blue color. The surface area of the cap has a velvety texture when young.

6. Short-stemmed slippery jack

The semi-viscous cap of the short-stemmed slippery jack (Suillus brevipes) is one of the older species of classified mushrooms and was first noted in scientific journals over 140 years ago. They grow quickly in fallen pine needles and are a favorite snacks of Grizzly bears.

7. Orange-capped bolete

Orange-capped bolete (Leccinum aurantiacum) is easily recognizable for its thick stalk and colorful red-orange cap. Bruised skin may turn burgundy before becoming gray. It sprouts in summer and autumn throughout North America and Europe, where it is particularly associated with the poplar tree.

8. Oyster mushroom

Oyster mushrooms grow wild but are also cultivated for sale in supermarkets. They can even be cultivated at home. They will grow on coffee grounds and spent grain, and are occasionally even fashioned into an environmentally-friendly substitute for styrofoam. There are several toxic look-alike species, so it is best to buy these mushrooms at the store.

9. Blotched woodwax

Blotched woodwax has a bright white to pink cap that helps distinguish it from similar species. The gills have a reddish-pink discoloration and juveniles do not have partial veils. Blotched woodwax thrives in spruce and conifer forests and grows in chalky soil.

10. Western giant puffball

The western giant puffball is the largest puffball in North America, reaching up to 70 cm in diameter. It is as large as its European counterpart the Giant puffball (Calvatia gigantea), although it features a more irregular shape than its European cousin.

11. Giant sawgill

The impressively large caps of the giant sawgill (Neolentinus ponderosus) can spread up 30 cm across and encompass entire decaying stumps and logs. Unlike other mushrooms, the giant sawgill thrives in the hotter, drier months. Look for them near Ponderosa Pines.

12. Purple coral

The purple coral is a tiny, but beautiful and impressive fungus that can be immediately distinguished from other Alloclavaria and Clavaria species by its distinctive purple colour. This mushroom grows in large clusters, but it's still unclear whether it's a saprobic or mycorrhizal species.

13. Common stinkhorn

The common stinkhorn (Phallus impudicus) grows incredibly quickly, sometimes nearing 30 cm in a single afternoon. Their caps are pitted in a way which makes them reminiscent of morels. However, there's little mistaking the common stinkhorn for a morel; the former, in addition to sporting a much longer stalk, has a clear and pungent odor.

14. Salt-loving mushroom

The salt-loving mushroom (Agaricus bernardii) is a globally-distributed species that has a fondness for microhabitats that are, you guessed it, salty! Salt marshes, coastal grasslands, and even recently salted roads and sidewalks play host to this agaric species, which is stocky in stature and has a white or off-white cap.

15. Lung oyster

Developing all around the northern hemisphere, lung oyster mushrooms grow in overlapping shelf-like clusters on deciduous branches, trunks, and fallen logs in the wild. They are easy to cultivate on other substrates, like spent coffee grounds and sawdust, for commercial production. They are generally considered safe to eat, although some people may develop allergies.

16. Meadow mushroom

The meadow mushroom grows in meadows and pastures around the world—especially those rich in manure—when the weather is warm and wet. They are known to appear in “fairy ring” shapes. Originally identified in Europe, it is possible that North American specimens identified as meadow mushrooms may genetically belong to other species.

17. Pig's ears

The pig's ears (Gomphus clavatus) forms unusual-looking fruitbodies. Several mushroom caps develop from a single stem, and often fuse the edges of their caps together. This growth pattern creates a shape reminiscent of the folds of an ear. Unfortunately, it is listed as a threatened species in some parts of the world, due to destruction of old-growth forests.

18. Saffron milk cap

Growing wild in the northern hemisphere and introduced to Australia, the saffron milk cap is found in pine forests during autumn. As the name implies, these mushrooms have been harvested for cooking for a long time. They have been known to cause stomach upset in some individuals, however, and carry a risk of being contaminated with heavy metals, so forage with caution.

19. Clustered collybia

Clustered collybia is the only species within the Connopus genus. As its name implies, the Clustered collybia grows in remarkably dense clusters on rotting conifer logs and stumps. The cap is somewhat slippery, and it fades from reddish-brown to greyish-tan.

20. Sculpted puffball

Sculpted puffball is an eye-catching and unique puffball that appears to have been sculpted with pyramidal warts, giving rise to its name. Sculpted puffball fruits during the late spring/early summer in the soil of conifer forests at altitude. It can be mistaken for the larger C. subsculpta.
