A very large and diverse family of mushrooms, pale-spore mushrooms (Tricholomataceae) includes some excellent edible species, but also some that are severely poisonous. As their common name suggests, all these mushrooms have a pale spore print. The large majority of these fungi are saprophytic, meaning they feed on dead and decomposing plant matter.
Pale-spore mushrooms includes both poisonous and nonpoisonous fungi. Tricholoma pardinum causes severe gastroenteritis if ingested. Other toxic members include Clitocybe dilatata, while some, like the Fairy ring mushroom (Marasmius oreades), are nontoxic.
