Potential benefits and harms: a review of poisonous mushrooms in the world

Abstract

Mushrooms have long been considered as delicacies as well as used as important dietary supplements and food. However, there are major concerns with poisonous mushrooms as these pose threats to public health and safety. In this paper, we provide a review focusing on poisonous mushrooms, their toxins, symptoms and utilizations. In addition, this paper establishes a poisonous mushroom list which includes 643 species from two phyla, 16 orders, 51 families and 148 genera. The toxicity of all these species was verified and 332 species were ranked as P1 signifying that these species have toxic studies and or clinical poisoning case records and 311 species were P2 meaning they had previously been recorded as poisonous in other studies. Furthermore, we discuss advances in technology including how genomic studies could be used as a breakthrough tool in the field of toxic mushrooms. With this comprehensive review, we aim to promote public awareness of poisonous mushrooms, including how to avoid mushroom poisoning, and how to better utilize poisonous mushroom resources.
