The colour of C. violaceus cannot be converted to a dye, unlike that of some other Cortinarius species, such as C. sanguineus and C. semisanguineus. Big, beautiful mushroom with a rich violet cap; browns with age. It is the type species of the genus Cortinarius, but is readily distinguished from other species in the genus by its dark colouration and distinct cystidia.

Stems: 6–15 cm long x 1–2 cm wide, distinctly longer than the cap is wide. It is an iron(III) complex of (R)-3′,4′-dihydroxy-β-phenylalanine [(R)-β-dopa]. Economically important fungi such as edible and medicinal mushrooms will be identified and their collection and local cultivation strategies will be planed. [5] French naturalist Jean-Baptiste Lamarck viewed it as a variety (violaceus) of a variable species he described as Amanita araneosa in 1783,[6] and Christiaan Hendrik Persoon placed it in the Section Cortinaria of Agaricus in his 1801 work Synopsis Methodica Fungorum. The species was first described by Carl Linnaeus in 1753, and has undergone several name changes. In 1891, his countryman Otto Kuntze published Revisio Generum Plantarum, his response to what he perceived as a poor method in existing nomenclatural practice. [14] Although widespread, it is not common anywhere in Europe,[17] and it is listed as endangered in the British Isles. (Edible.) MyCoPortal. Have a bunch of mushrooms and need some inspirational recipes? [2] The specific epithet violaceus refers to the deep violet colour of its cap. Cortinarius Violaceus. [13] A large number of cystidia are present, and, individually, they measure between 60 and 100 µm by between 12 and 25 µm. Its similarity to some other (inedible or toxic) webcaps renders it risky to eat.The taste after cooking is reportedly bitter.

[3], The colour of C. violaceus cannot be converted to a dye, unlike that of some other Cortinarius species, such as C. sanguineus and C. [14], A 2015 genetic study by evolutionary biologist Emma Harrower and colleagues of C. violaceus and its closest relatives suggests that the group (section Cortinarius) originated in Australasia and began diverging from a common ancestor around twelve million years ago in the Miocene, with C. violaceus itself diverging from its closest relative around 3.9 million years ago. [13] The species was one of only two placed in the Cortinarius subgenus Cortinarius by the Austrian mycologist Meinhard Moser. Violet webcaps are considered edible and they have not been implicated in the poisoning records of the North American Mycological Association. A drop of 3% KOH will turn the flesh blood red. Cortinarius violaceus mushroom. The fact that these species diverged relatively recently indicates that some form of dispersal must have taken place across large bodies of water.

Yet another from Eastern Australia has been named C. [13] The flesh is violet, but darker below the pileipellis and in the stipe. A popular guide to the identification and study of our commoner Fungi, with special emphasis on the edible varieties. Cup: none. Habitat: on the ground, in the Pacific northwest and BC often in mixed forests with Sitka spruce (Picea sitchensis), western hemlock (Tsuga heterophylla), pines (Pinus sp.) The dark flesh has a smell reminiscent of cedar wood. The stalk measures 6 to 12 centimetres (2 1⁄3 to 4 2⁄3 in) by 1 to 2 centimetres (3⁄8 to 3⁄4 in), sometimes with a thicker base. Though they are sometimes described as edible, the appearance of these mushrooms is more distinctive than their taste. The fruit bodies have small, slimy, purple caps up to 6 cm (2.4 in) in diameter that develop yellowish spots and streaks in maturity. aff. [7] Cortinarius was established as a genus by English botanist Samuel Frederick Gray in the first volume of his 1821 work A Natural Arrangement of British Plants, where the species was recorded as Cortinaria violacea, "the violet curtain-stool". These species are differentiated morphologically by the latter population's rounder spores. Cortinarius iodes, commonly known as the spotted cort or the viscid violet cort, is a species of agaric fungus in the family Cortinariaceae. A beautiful, little-known to a wide range of mushroom pickers and edible purple spiderweb (Cortinarius Violaceus), a representative of agaric mushrooms, included in the Spiderweb family and the Spiderweb genus, grows in deciduous and coniferous forests of Austria, England, Denmark, Czech Republic, Ukraine and Italy. Due to its swollen, bulbous nature, the base of the stipe can sometimes be as wide as 4 centimetres (1 1⁄2 in). British Columbia: 604-682-5050 or 1-800-567-8911. No records of association with oak (Quercus) are known from this region. Bui. [25], In North America, C. violaceus favours conifers, and, though rare over much of the continent, is relatively common in certain areas, including Mount Rainier National Park and Olympic National Park. There are some populations that seem to prefer deciduous trees and others that prefer pines, but no genetic divergence between the two has been found. In colour, it is a dark violet to blue-black, and is covered in fine, downy scales. [4][20] The taste after cooking is reportedly bitter. It grows with deciduous trees, but also found with conifers, often on acidic soil.
