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.
Symptoms can vary from slight gastrointestinal discomfort to death in about 10 days. Mushroom toxins are secondary metabolites produced by the fungus. Mushroom poisoning is usually the result of ingestion of wild mushrooms after misidentification of a toxic mushroom as an edible species.
Amatoxin is the collective name of a subgroup of at least nine related cyclic peptide toxins found in three genera of deadly poisonous mushrooms (Amanita, Galerina and Lepiota) and one species of the genus Pholiotina. [1] Amatoxins are very potent, as little as half a mushroom cap can cause severe liver injury if swallowed.
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.
The spores are 4–7 by 2–3 μm, oblong-elliptical, smooth, and embedded in the gleba. [9] A 1982 study revealed that spores of species in the family Phallaceae , including Mutinus elegans , have a hilar scar (0.2–0.3 μm diameter) that is observable with scanning electron microscopy .
The fruiting body, or mushroom, is an irregular brain-shaped cap dark brown in colour that can reach 10 centimetres (4 inches) high and 15 cm (6 in) wide, perched on a stout white stipe up to 6 cm (2 + 1 ⁄ 2 in) high.
The fruitbodies (mushrooms) grow on rotting wood, especially wood chips used in garden landscaping. The caps of the mushrooms are brown to buff , broadly convex to flattened and have a diameter up to 9 cm (3.5 in), while the white stipes are up to 9 cm (3.5 in) long and 0.7 cm (0.3 in) thick.
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.
