[Clinical importance of the Gavornik classification of mushroom poisoning].

The lack of experience and fundamental knowledge about mycology by some mushroomers is one of the leading causes of increasing occurrence of fatal mushroom poisonings. Mushroom intoxications are caused not only by poisonous mushrooms (true primary intoxications), but under certain conditions also by edible mushrooms (secondary intoxications, false intoxications, pseudo-intoxications). Apart from fresh mushrooms intoxications may result also from preserved mushrooms (sterilized in pickles, soured, dried, used for preparation of mushroom extracts, powders, etc.), which are used as garnish.
