Mushroom toxins have appeared and disappeared many times throughout their evolutionary history. [32] Many scientists believe that the toxins evolved in mushrooms are used to deter predation, either from fungivores or mammals. [33] If mushrooms are consumed, it can negatively affect their ability to disperse spores, survive, and
Previous studies have demonstrated that younger mushrooms can contain a higher concentration of toxins than is found in mature specimens. [28] The combined weight of the caps of these two mushrooms was 43.4g fresh or 4.3g when dry and when tested were found to contain a total of 21.3 mg of amatoxin distributed as 11.9 mg alpha-amanitin, 8.4 mg ...
Terana coerulea with Puntelia lichen. The blue pigment of this fungus was shown to be a mixture of polymers structurally related to thelephoric acid. [10]When activated by external treatments such as high temperature (42 °C (108 °F)), exposure to vapors of toxic solvents, or contact with a water-toluene mixture, T. caerulea produces an antibiotic named cortalcerone (2-hydroxy-6H-3-pyrone-2 ...
The species was first described scientifically by American mycologist Howard James Banker in 1913. [2] Italian Pier Andrea Saccardo placed the species in the genus Hydnum in 1925, [3] while Walter Henry Snell and Esther Amelia Dick placed it in Calodon in 1956; [4] Hydnum peckii (Banker) Sacc. and Calodon peckii Snell & E.A. Dick are synonyms of Hydnellum peckii.

Hypholoma fasciculare, commonly known as the sulphur tuft or clustered woodlover, is a common woodland mushroom, often in evidence when hardly any other mushrooms are to be found. This saprotrophic small gill fungus grows prolifically in large clumps on stumps, dead roots or rotting trunks of broadleaved trees.
Amanita verna, commonly known as the fool's mushroom or the spring destroying angel (see destroying angel), [2] is a deadly poisonous basidiomycete fungus, one of many in the genus Amanita. Occurring in Europe in spring, A. verna associates with various deciduous and coniferous trees.
The genus Amanita was first published with its current meaning by Christian Hendrik Persoon in 1797. [1] Under the International Code of Botanical Nomenclature, Persoon's concept of Amanita, with Amanita muscaria (L.) Pers. as the type species, has been officially conserved against the older Amanita Boehm (1760), which is considered a synonym of Agaricus L. [2]
