Most Common Toxic or Poisonous Mushrooms
1. Powdered sunshine lichen
Vulpicida pinastri usually has few, broad, irregular lobes whose edges are lined with yellow Bortensoralen. On the underside, the lichen is pale yellowish with few rhizins. Fruit bodies (Apotheciens) are very rarely trained and then have a brown disc with bearing edge. The unicellular spores are ellipsoidal to almost spherical. The yellow color is caused by the highly toxic vulpinic acid in the marrow, which probably serves as a feeding protection against snails.
2. Yellow stainer
The yellow stainer grows across North America and Europe and has been imported to Australia. It can be distinguished from other common white mushrooms by the bright chrome yellow color it turns when bruised. It is known to be poisonous, causing cramps, nausea, and purging. Unfortunately, it often gets accidentally eaten as it looks similar to several edible white mushrooms.
3. Mower's mushroom
The mower's mushroom, also referred to as the lawnmower's mushroom, is so named because it frequently crops up in lawns. The species is rather nondescript, and it is considered a member of the infamously hard-to-distinguish "Little Brown Mushroom" (LBM) family. While the mower's mushroom is not known to be toxic to humans or dogs, several of these close look-alikes are.
4. 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.
5. 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."
6. Common ink cap
Common ink cap mushrooms grow in clumps from buried wood or tree stumps. They come up with such strength that they have been known to lift pavement or break through asphalt. As they age, their gills will turn black and liquefy, creating the "inky" substance for which they are named.
7. Wolf lichen
The thallus, or vegetative body, has a fructicose shape — that is, shrubby and densely branched — and a bright yellow to yellow-green, or chartreuse color, although the color will fade in drier specimens. Its dimensions are typically 2 to 7 cm (0.8 to 3 in) in diameter. The vegetative reproductive structures soredia and isidia are present on the surface of the thalli, often abundantly. 
8. 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.
9. Shaggy parasol
The shaggy parasol grows singly or in groups from spring to fall. It can be found in lawns and gardens as well as the forest. It has a tendency to cause allergic reactions. Take care with identification as it is difficult to distinguish from the more deadly Amanitas.
10. False chanterelle
The common name of this mushroom refers to the fact that it looks very similar to the edible and highly prized Chanterelle. This species, however, tastes bitter and may cause poisoning symptoms. False chanterelle occurs around the northern hemisphere in autumn and winter, growing on coniferous detritus, and is more likely to fruit in dry conditions rather than the usual wet.
