Wild mushroom poisoning from the genus Amanita is a medical emergency, with Amanita phalloides being the most common offender. Patients may complain of nausea, vomiting, diarrhea and/or abdominal pain. If not aggressively treated, fulminant hepatic failure may develop within several days of ingestion. In this case report, a patient poisoned with Amanita bisporigera is described, along with the ...

We collected nearly 70 specimens of Amanita species during a diversity study of Korean mushrooms conducted in 2012. In this study, we primarily investigated 23 Amanita specimens belonging to sections Amanita and Vaginatae. Based on sequence data of the internal transcribed spacers and partial large subunit of ribosomal RNA and morphological characteristics, we identified the following 15 phylog...

The heavy metals (Cd, Cr, Ni, Pb, Zn, Cu, Fe, Mn) content of some edible wild mushrooms (Amanita caesarea, Amanita rubescens, Amanita vaginata, Amanita spissa) and soil samples, of ten sites from Dambovita county Romania, were analyzed. Elements concentrations were determined by Flame Atomic Absorption (FAA) spectrometry and Energy Dispersive X-ray spectrometry (EDXRF) in 40 samples of Amanita ...

Amanita Pers. is a well-known monophyletic mushroom genus with a broad distribution. However, the diversity of Korean Amanita species has been underestimated, and most taxonomic studies conducted in Korea have only investigated their morphological characteristics. This approach is frequently insufficient for correct identification in fungal classification; therefore, we constructed a phylogeny ...

Conclusions: Amanita phalloides intoxication can be successfully treated with N-acetylcysteine in addition to the standard regimen. Significantly, the simplicity of administration, good tolerance, and an affordable cost make N-acetylcysteine a viable option for the treatment of Amanita phalloides intoxication. The low mortality rate presented in the study group may be ascribed to N-acetylcystei...

The phylogenetic relationships, taxonomy and biogeography of the genus Amanita with emphasis on eastern Asian species were estimated using sequence data from both internal transcribed spacer (ITS) regions and large subunit (nLSU) of nuclear ribosomal DNA. The separation of the two traditionally accepted subgenera was not well supported. Each section of Amanita, Vaginatae, Caesareae, Phalloideae...

Amanita phalloides-type mushroom poisoning is well recognized as causing acute liver injury and often death. Less is known, however, of whether maternal Amanita poisoning is associated with fetal damage or not. In August 1991 four members of a family were hospitalized with food intoxication caused by Amanita phalloides and Amanita verna. One of them died from hepatic and renal failure. The surv...

The genus Amanita has been divided into two monophyletic taxa, Amanita, an ectomycorrhizal genus, and Aspidella, a saprotrophic genus. The controversies and histories about recognition of the two genera based on trophic status are discussed. The name Aspidella E.-J. Gilbert is shown to be illegitimate and a later homonym of Aspidella E. Billings, a well-known generic name for an enigmatic fossi...

The genus Amanita encompasses both symbiotic, ectomycorrhizal fungi and asymbiotic litter decomposers; all species are derived from asymbiotic ancestors. Symbiotic species are no longer able to degrade plant cell walls. The carbohydrate esterases family 1 (CE1s) is a diverse group of enzymes involved in carbon metabolism, including decomposition and carbon storage. CE1 genes of the ectomycorrhi...
