Most Common Mushrooms

False parasol

1. False parasol

Though the false parasol appears unassuming, the species is famous—or, infamous—for its toxicity. It looks unfortunately similar to Agericus campestrus, a commonly eaten mushroom, but the false parasol can be distinguished by its highly unusual green spore print. Although they are no good to eat, they can be pretty to look at. The species may grow in ring-shaped groups in meadows and on forest floors in what are sometimes called "fairy circles."
Chicken-of-the-woods

2. Chicken-of-the-woods

Chicken-of-the-woods is a brightly-colored polypore related to the famed Chicken-of-the-Woods (Laetiporus sulphereus). The species are so closely related, that it was not until the 2000s that mycologists considered them to be distinct. Unlike its famed relative, the species is not considered a choice edible - there are conflicting reports as to its edibility, with some probable cases of gastrointestinal distress noted.
Split gill

3. Split gill

Split gill(Schizophyllum commune) can be found across the globe. Uniquely, it is the only mushroom species known to display the capability to retract by movement. It is considered inedible, although not necessarily toxic. Furthermore, it is not recommended to smell this species, as the spores are capable of sprouting and growing in nasal passages.
Hairy curtain crust

4. Hairy curtain crust

This clustered, overlapping fungus is found all over the world, and is considered native across both the northern and southern hemispheres. Both its common name, hairy curtain crust, and its scientific name, Stereum hirsutum, aptly describe its most obvious features: it is quite tough (stereum) and the younger fruitbodies are notably hairy (hirsutum).
Yellow fieldcap

5. Yellow fieldcap

Yellow fieldcap can be found across Europe and North America, with dung patties or heavily-manured fields being its favorite fruiting habitat. The species sometimes goes by the common name Yellow Fieldcap because its young cap sports a bold yellow or golden hue (that color often fades as the mushroom cap matures and flattens). Yellow fieldcap is not know to be edible.
Bright cobblestone lichen

6. Bright cobblestone lichen

Turkey tail

7. Turkey tail

The distinctively-striped turkey tail fungus grows on stumps and logs all over the forests of the northern hemisphere. It is, in fact, probably the most common species you will find. That doesn't mean this mushroom is plain, however; each cap is uniquely patterned. Look for bands of alternating textures as well as color.
Big sheath mushroom

8. Big sheath mushroom

These large white mushrooms bloom all over cleared, harvested fields, as well as pastures and roadsides. The scientific species name comes from Greek words meaning “glue” (glioio) and “head” (cephalus), in reference to the sticky surface of this mushroom’s cap. The big sheath mushroom looks so similar to the poisonous Deathcap and Destroying Angel mushrooms that it should always be left alone.
Western jack-o'-lantern mushroom

9. Western jack-o'-lantern mushroom

The western jack-o'-lantern mushroom (Omphalotus olivascens) may be the most visually striking mushroom of the forest during day and night. During the day, brilliant large orange flat caps grow from both the ground and decaying stumps. At night, these mushrooms may glow in the dark, depending on location and maturity.
Redlead roundhead

10. Redlead roundhead

This colorful mushroom grows most commonly on woodchip mulch and in sandy pine forests of coastal areas around the world. The redlead roundhead is believed to have originated in Australia. It may look pretty enough to eat, but don’t; it is bitter, toxic, non-digestible, and likely to cause an upset stomach.
