Top 20 Most Common Toxic or Poisonous Mushrooms in Greece

During the reproductive phase of its life cycle, Spinellus fusiger grows throughout the cap of the mushroom host, eventually breaking through to produce radiating reproductive stalks (sporangiophores) bearing minute, spherical, terminal spore-containing structures called sporangia. Ultimately, the spores in the sporangia are released after the breakdown of the outer sporangial wall, becoming passively dispersed to new locations via wind, water, and insects. The sporangia contain non-motile mitospores known as aplanospores. Like other Spinellus species, S. fusiger is homothallic, a condition where sexual zygospores can be produced union of branches from the same mycelium and so can be produced by the growth from a single spore.

The woolly chanterelle, which looks only vaguely similar to its famed, edible chanterelle cousins, is vase-shaped and has large, pale folds and wrinkles on its underside (as opposed to having gills, like those of more sought-after chanterelles). Woolly chanterelles can cause upset stomach, vomiting, and diarrhea in some who eat them, while leaving others completely unaffected. Needless to say, the species is not considered a "choice edible".

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.

Angel wings(Pleurocybella porrigens) is a delicate, almost ethereal mushroom most commonly found on decaying conifer logs and stumps. In spite of its disarming name, this species is highly toxic and should not be consumed under any circumstances; once considered edible, it has been responsible for numerous deaths in Japan.

The onion earthball is a member of the "tough-skinned puffball" family, a group of mushrooms that are typically bulbous and puff-ball like in form but have a tough outer layer. In the onion earthball's case, that outer layer often fissures, giving the mushroom a cracked appearance. Also distinctive is the stark contrast between this mushroom's skin, usually a pale white or yellow color, and its inner spore tissue, which is nearly black. Onion earthballs are poisonous.

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.

Small funnel-veil amanita thrives primarily in deciduous forests but is also found growing underneath conifers. Its umbrella-shaped cap covered with small warts makes it easy to spot, along with its cream-colored stem.

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.

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.

The black bulgar is an unusual fungus that looks a bit like black gumdrops. While some authorities classify it in an "unknown edibility" group, others claim it's a poisonous mushroom. Either way, its unappealing appearance surely makes it an easy choice not to consume the black bulgar.
