Numerous severe cases of neurotoxic mushroom poisoning worldwide are caused by ibotenic acid and muscimol produced by specific species belonging to section Amanita of the genus Amanita. Recent studies have demonstrated that both toxins are produced through the ibotenic acid biosynthetic gene cluster (iboBGC) in these species. In addition to these two toxins, section Amanita is also thought to...

Globally, many species of Amanita sect. Amanita (Amanitaceae, Agaricales) cause poisoning after consumption. Amanita flavomelleicepssp. nov. and Amanita parvisychnopyramissp. nov., two new species of A. section Amanita from China, are described here. Morphology and molecular phylogenetic analyses based on five genes (ITS, nrLSU, RPB2, TEF1-α, and TUB2) revealed these two taxa as distinct...

The genus Amanita sect. Amanita harbors approximately 150 species in the world, and 27 species have been recognized in China. Some of the species in China have continuously caused poisoning. The responsible toxins should be ibotenic acid (IBO) and muscimol (MUS). However, species of the section Amanita containing IBO and MUS and their systematic positions are unclear. In this study, the...

Many species of Inosperma cause neurotoxic poisoning in humans after consumption around the world. However, the toxic species of Inosperma and its toxin content remain unclear. In the present study, we proposed five new Inosperma species from China, namely, I. longisporum, I. nivalellum, I. sphaerobulbosum, I. squamulosobrunneum, and I. squamulosohinnuleum. Morphological and molecular...
