BACKGROUND Although some Japanese Galerina species poisonings manifest as gastrointestinal symptoms followed by late-onset hepatorenal failure (phalloides syndrome), the toxin responsible for this has not been determined. CASE REPORT We report a 6-year-old boy who developed characteristic cholera-like diarrhea and late-onset severe hepatic deterioration after eating mushrooms, later identifie...

A bisabolane type of sesquiterpene was isolated from the culture medium of Amanita virgineoides BAS, together with two known compounds, including lignoren, and harziandion. The structure of the new compound "virgineol" was established using a combination of different NMR spectroscopy techniques, whereas the chemical structure of the known compound was identified as lignoren, and the structure o...

The article describes the red toadstool, Amanita muscaria, in mirror of history, natural medicine, content substances, and toxicity, as well within context shamanic, ritual, religious practices. Based on scientific reasons, a strong warning against any experimentation with consumption mushroom itself, or preparations prepared from it, is delivered.

Ectomycorrhizal (ECM) fungi are often considered to be most prevalent under conditions where organic sources of N predominate. However, ECM fungi are increasingly exposed to nitrate from anthropogenic sources. Currently, the ability of ECM fungi to metabolize this nitrate is poorly understood. Here, growth was examined among 106 isolates, representing 68 species, of ECM fungi on nitrate as the ...

Mushroom intoxication due to Amanita proxima poisoning is characterized by moderate gastrointestinal symptoms, followed by severe acute renal failure and sometimes by hepatic cytolysis. This syndrome was described in the 1990s in the southeast of France; we report here the first pediatric case, requiring dialysis but achieving complete recovery. The mother of this 11-year-old boy, who had eaten...
