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.
Bright cobblestone lichen

4. Bright cobblestone lichen

Redlead roundhead

5. 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.
Mica cap

6. Mica cap

The bell-shaped mica cap mushrooms grow in clusters on wood debris and stumps, from spring to autumn. The caps appear wet and inky once they mature and begin to release spores. At that point, they can be boiled with cloves to create a useful black ink.
Big sheath mushroom

7. 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.
Milky conecap

8. Milky conecap

A delicate little fairy-tale-looking mushroom, the milky conecap shows up in moist woodlands, fields, and lawns. The species' common name refers to its deep and pointed cap, which looks much like a garden gnome's hat. While the species is not known to be toxic, it is too small and delicate to bother with for culinary purposes.
Shaggy mane

9. 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.”
Ganoderma polychromum

10. Ganoderma polychromum

The ganoderma polychromum is a polypore mushroom that grows on wood. The members of the Ganoderma genus, including the Ganoderma polychromum, are so tough that they can be woodier than the tree or wood they feed on.
