Top 20 Most Common Toxic or Poisonous Mushrooms in Marietta

1. Peach-colored fly agaric

If you're looking for peach-colored fly agaric (Amanita persicina), start by hunting around in the leaf litter of hemlock, pine, and oak trees on the eastern coast of North America. Their rotund cap can commonly be overlooked, but well worth seeking out just to view the freckles and color. This species is poisonous, so take nothing but a photograph.

2. Flowerpot parasol

This tropical/subtropical mushroom is known to be toxic. If eaten it causes a very unpleasant stomachache with the risk of fatal complications. In temperate zones, flowerpot parasol is only found in hothouses and greenhouses, so the risk of accidental foraging is low, but it may occur with potted plants and indoor landscaping and pose a risk to curious children.

3. 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."

4. Jack-o'lantern mushroom

The jack-o'lantern mushroom is so-called because of its bright orange color, and because it often appears in the fall (usually before Halloween, though). This vibrant little mushroom can be found growing on decaying hardwood stumps and logs. The species does have some superficial resemblances to the highly edible chanterelle (Cantharellus cibarius), but it is toxic and should be avoided!

5. Rufous rubber cup

The rufous rubber cup is a tiny, cup-shaped, reddish-brown mushroom that commonly grows on twigs and fallen branches. The species is considered inedible, and its modest look almost certainly wouldn't attract anyone to consume it.

6. Fragile dapperling

The fragile dapperling is a tropical and subtropical woodland species. As its name suggests, this mushroom is so tender and fragile that picking it becomes a real challenge. The stem is very thin and it easily snaps. The edibility of the fragile dapperling is unknown, but the mushroom is probably insufficient for any kind of meal.

7. Dead man's hand

Sometimes referred to as a "false Truffle", a trained eye could not easily mistake the dead man's hand for these highly-valued mushrooms. This large puffball-like mushroom develops in the ground, emerging gradually until it finally cracks up and forms a star-shaped fruiting body. The dead man's hand is considered toxic and newbie mushroom hunters should be careful not to confuse it with edible puffballs.

8. Yellow patches

The yellow patches is a gorgeous, striking species with a deep marigold or vermillion cap that sometimes appears as a blend of the two. Like some other members of the Amanita genus, it also sports patchy white worts - when it's cap is still very convex, it somewhat resembles the famous white and red mushrooms from the Mario Bros video games. While beautiful to look at, this species is toxic and should not be harvested.

9. Ravenel's bolete

The ravenel's bolete is an unusual and unmistakable mushroom — unlike all other bolete mushrooms, this species has a powdery veil that covers the pores and the part of the stem when still young. The veil is bright yellow, almost fluorescent. Ravenel's bolete has been used for making mushroom-based dyes.

10. Sulphur tuft

The sulphur tuft grows on rotting wood of all types of trees; it is a particularly efficient decomposer of hardwoods. The mushrooms appear from spring to autumn and are often so tightly packed that they interfere with each other’s shape. This poisonous mushroom can cause temporary paralysis, distorted vision, and stomach pain if consumed.

11. Coker's amanita

Coker's amanita may appear similar to other Amanita mushrooms but can be distinguished through careful observation of its features. The large size of this mushroom is one of its most distinctive features. This mushroom can be found in a variety of situations, growing alone or in groups, forming connections with hardwoods or conifers, and growing in the summer to fall season.

12. Onion-stalk parasol mushroom

This generalist mushroom, found across North America, can be found in all sorts of moist woodland settings. The species appears to be particularly fond of wood chips or mulch, and so it is often found in garden or park settings. The onion-stalk parasol mushroom, despite the word "onion" in its name, is inedible.

13. Common earthball

With an appearance similar to a crusty potato, the common earthball blooms from acidic soils, including compacted paths on the forest floor. It matures to a yellowish tinge and is found across the northern hemisphere. It is a close cousin to bolete mushrooms but is considered to be poisonous and is never eaten.

14. Brick cap

This tufting mushroom grows on hardwood stumps and deadwood. The brick cap seems particularly fond of oak wood. It is similar in most respects to the Sulfur Tuft or Conifer Tuft, except that its cap is a brick red color. Brick caps should be regarded as inedible and are likely to cause stomach problems if consumed.

15. Cleft-footed amanita

The cleft-footed amanita is a North American mushroom species that was once classified as the notorious Amanita phalloides (the Death cap). Although later found to be less deadly, the cleft-footed amanita is a highly variable species that is not considered safe to forage for consumption.

16. Eastern american floury amanita

Eastern american floury amanita can be found during the late summer to fall in woodland areas. As hinted by its name, young mushrooms are covered in a flour-like powder that may wear off in older mushrooms. Other Amanitas can appear similar, but these mushrooms often have a ring of flesh around the stem and a cup-shaped structure at the base of the stem, which eastern american floury amanita lacks.

17. Yellowdrop milkcap

The yellowdrop milkcap is a severely toxic mushroom that causes gastrointestinal disturbances. When cut or bruised, it produces the white milky latex that dries yellow on damaged places just in a few seconds. These bright yellow spots are the best way to distinguish the species.

18. American abrupt-bulbed amanita

American abrupt-bulbed amanita looks almost indistinguishable from other Amanita species in most ways. However, as hinted by its name, american abrupt-bulbed amanita has a distinctively shaped base. This unique appearance has been described as a mushroom stem growing from the lower half of an egg.

19. Cinnamon bracket

The cinnamon bracket (Hapalopilus rutilans) is a fungus that causes a white rot on dead wood. Its poisonous fruit bodies appear as brackets, and tend to grow in a dull orangish shade. A chemical reaction with ammonia, however, turns it purple. This fact can be exploited for the creation of wool dyes, with colors ranging from light lavender to deep purple.

20. Freckled dapperling

Freckled dapperling grows on decaying wood most commonly in woodlands but also on mulch or in gardens. Unfortunately, this mushroom may be indistinguishable from other species in the same genus, Echinoderma, without close inspection. However, its pyramid-shaped scales, as referenced by its name, are one aspect that can help differentiate freckled dapperling.
