Amanita calida is illustrated and described from collections made in Andalusia Catalonia, a Mediterranean environment, associated with Quercus. Macroscopically, this species characterized by whitish, beige to grayish cuticle, sometimes prominent darker brown umbo, widely striated margin of the pileus, very elongated stipe proportion diameter whitish or similar but fainter shades those pileus; s...

The determination of the two isomers amavadin and other V species in Amanita muscaria with HPLC-ICPMS.

This article presents a comprehensive review of amatoxin poisoning. The article discusses the biochemistry of amatoxin, as well as the clinical manifestations of amatoxin ingestion. In addition, the evaluation of the patient with amatoxin ingestion is discussed, along with the treatment – including newer therapy – and the ultimate prognosis of the syndrome. *Corresponding author: Bobby Desai, D...

Ingestion of mushrooms from the genus Amanita can present detrimental consequences to the human body. The mushroom is frequently found in the coastal Pacific Northwest, Pennsylvania, New Jersey, and Ohio. Amanitin, one of the two distinct toxins isolated from the Amanita mushroom, is responsible for the majority of symptoms and signs seen with mushroom poisoning. Clinically, ingestion of these ...

<em>Amanita indogrisea</em> is described here as a new species from coniferous forests in the Union Territory of Jammu and Kashmir, India based on morpho-anatomy molecular data. This characterized by its small to medium-sized basidiomata, ash grey lilac-grey pileal surface with greyish brown pulverulent-floccose felted veil remnants, greyish-white stipes ovoid ellipsoid basal bulb, ...

The accurate classification of Amanita is helpful to its research on biological control and medical value, it can also prevent mushroom poisoning incidents. In this paper, we constructed the Bilinear convolutional neural networks (B-CNN) with attention mechanism model based transfer learning realize Amanita. When trained, weight ImageNet used for pre-training, Adam optimizer update network para...

The peptide toxins of poisonous Amanita mushrooms are bicyclic octapeptides (amatoxins) or heptapeptides (phallotoxins). In Amanita bisporigera, alpha-amanitin and phallacidin are synthesized as 35- and 34-amino acid proproteins, respectively, in which the amino acid sequences found in the mature toxins are flanked by conserved amino acid sequences. The presence of invariant Pro residues immedi...
