Most Common Mushrooms
1. Lobster mushroom
The lobster mushroom is actually not a species of mushroom, per-se. When Hypomyces lactifluorum mold attacks one of several common species of Russula mushrooms, it transforms them into lobster mushrooms: they shrivel, harden slightly, and turn bright orange or vermillion. Surprisingly, this only makes them more flavorful. Lobster mushrooms are highly sought after for their distinctive, seafood-like flavor when cooked. Upset stomachs have been reported when eaten raw.
2. Fly agaric
In Northern Asia and Europe, fly agaric grows under trees near the winter solstice and is collected for ritual use tied to the season. Its characteristic shape and coloring are still ubiquitous in many European fairy tale illustrations and Christmas traditions. It is highly toxic.
3. Shaggy scalycap
These mushrooms are most commonly found in clusters underneath old broadleaf trees and on their stumps. Their scientific name, Pholiota squarrosa, means “scaly with upright scales,” and that is exactly how the surface of the mushrooms appears. They are sometimes mistaken for honey fungus, as they share the same color, but the shaggy scalycap is definitely not edible.
4. Artist's conk
This shelf fungus can live for several consecutive years and can be dated by the growth ridges seen on its dark surface. Artist's conk grows in tiered groups at the bases of oak, beech, and conifers, as well as deadwood. When its spores release, they cover the area with visible brown dust. Scratches in the white undersurface create dark lines.
5. 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.”
6. Bitter false funnelcap
Bitter false funnelcap (Leucopaxillus gentianeus) is most commonly found beneath conifers in Europe and North America. An exceptionally bitter mushroom, it is prone to forming so-called fairy rings or, alternatively, broken arcs. It is considered inedible.
7. Aspen bracket
As hinted by its name, aspen bracket only grows on live aspen trees, causing trunk rot. Despite its negative reputation with aspen trees, this mushroom serves as nesting sites for some birds. The fruiting bodies of aspen bracket add on a new layer each growing season and can persist for several years.
8. Dyer's polypore
This shelf fungus grows annually on living coniferous trees and may kill its host if left untreated. As the name suggests, dyer's polypore can be used to produce dye for yarn in a variety of shades from yellow to orange to brown, depending on the age of the mushroom used and also the type of metal it’s processed in. It is not considered edible.
9. Suillus kaibabensis
Suillus kaibabensis is a hardy yellow member of the genus Suillus. While yellow is the primary color, it can also include brown and white tones in varying degrees as well. This mushroom has a stem around 2–4 cm long, and 1–2 cm thick. The cap is broad and convex to flat, typical of many species of boletes. The stipe is bare, spotted with olive brown and can be reddish-brown at the base. The pores are yellowish-brown that can turn a salmon color with age. 
10. White king bolete
The habitat of the white king bolete is restricted to southwestern North America, but being a warm-weather species, it is most abundant in Arizona and New Mexico. The mushroom was given its scientific name Boletus barrowsii after the self-taught amateur mycologist Charles "Chuck" Barrows, who discovered the species just a few decades ago.
