“…A. smithiana contains A. smithiana toxin. Amanita boudieri, A. echinocephala, and A. gracilior also contain A. smithiana toxin and present similarly [4,5,129,[135][136][137][138][139]. A. smithiana toxin is not present in A. proxima , but the presentation, is nonetheless, similar [5,46].…”

“…Tubulointerstitial nephritis is characteristic. Mild cytolytic hepatitis can also be seen and the liver enzymes may rise before the creatinine rises [4,15,32,129,[135][136][137][138]. De Haro et al [140] reported on 53 patients poisoned by A. proxima and found 38 % had an increased creatinine, 32 % were oliguric or anuric, and 24.5 % required hemodialysis.…”

Approximately 100 of the known species of mushrooms are poisonous to humans. New toxic mushroom species continue to be identified. Some species initially classified as edible are later reclassified as toxic. This results in a continually expanding list of toxic mushrooms. As new toxic species are identified, some classic teachings about mycetism no longer hold true. As more toxic mushrooms are identified and more toxic syndromes are reported, older classification systems fail to effectively accommodate mycetism. This review provides an update of myscetism and classifies mushroom poisonings by the primary organ system affected, permitting expansion, as new, toxic mushroom species are discovered.

“…Amanita proxima or Amanita smithiana are known to cause accelerated renal failure, which is usually reversible and responds well to treatment. 4,5 In contrast, the onset of gastrointestinal symptoms caused by Cortinarius species of mushrooms containing orellanine can take several days, with the majority of cases progressing to chronic renal failure. 6 The fact that our patient responded well to treatment and recovered with no residual kidney damage lends credence to Amanita proxima or Amanita smithiana being the causative mushrooms (Figure 1).…”

A wild mushroom grows abundantly in the tropical belts of India, and they form part of the diet among the ethnic tribes. However, wild mushrooms are toxic, and some cause organ failure, namely fulminant hepatitis and kidney injury. Mushroom poisoning is frequently diagnosed based on clinical suspicion, and death has been reported commonly because of the consumption of amatoxin-containing mushrooms. In this article, we discuss three cases of amatoxin-induced mushroom poisoning that resulted in acute kidney and liver failure, requiring intensive medical management and renal replacement therapy. One of these patients died from irreversible fulminant hepatitis.

“…[ 1 ] The latter is morphologically similar to A. proxima , a nephrotoxic species containing the amino acid allenic norleucine, implicated in several poisonings. [ 2 - 5 ] Li Cavoli et al . (2019)[ 1 ] based their conclusions on the opinion of a single mycologist (the identity of whom is not disclosed, nor is the exact method of determination), who reportedly examined “remaining parts” of the collected basidiomes and identified the species as “ A. ovoidea .” The authors also provide two ex situ photographs of at least five collected basidiomes, none of them in pristine condition.…”
