Collybia personata (also recognised as Lepista personata, Lepista saeva, Clitocybe saeva and Tricholoma personatum, and commonly known as the field blewit and blue-leg) is a species of edible fungus commonly found growing in grassy areas across Europe and is morphologically related to the wood blewit Collybia nuda (formerly Lepista nuda). This mushroom was moved to the genus Collybia in 2023. [1]
This species was originally proclaimed by Elias Fries in 1818, as Agaricus personatus. Cooke proposed in 1871 another name still in use until recently — Lepista personata. Other names were to follow, namely Lepista saeva by P.D. Orton in 1960 and Clitocybe saeva by H.E. Bigelow & A.H. Smith in 1969, the latter placing the fungus in the larger genus Clitocybe . [2] In Latin, the specific epithet sævus is an adjective meaning either fierce, outrageous, angry or strong. Likewise, personatus is a participle meaning disguised, pretended or false. [3]
The fruiting body of the mushroom resembles an agaric. The cap is at first hemispherical or convex, becoming almost flat with maturity, up to 16 cm in diameter. The cap cuticle is colored cream to light brown with a smooth texture to the touch, and is often seen glistening when fresh. Along the periphery, the cap ends in a thick incurved margin which may unfold as the mushroom expands. The white to pallid flesh is thick, firm and delicate upon slicing. The underside of the cap bears crowded pinkish, cream to light brown gills, which are free or emarginate in relation to the stem. The stem itself is cylindrical with a bulbous, or sometimes tapering base, and does not bear a ring. The stem is covered by a striking lavender or lilac-coloured fibrous skin which fades in older individuals, and has a thick, firm flesh concolorous with that of the cap. It is up to 6–7 cm tall and 2.5–3 cm in diameter. [4] [5]
Under a light microscope, the spores are seen hyaline to pink, ellipsoid in shape, and with fine warts. The spore dimensions are 6-8 by 4-5 μm. C. personata produces a pale pink spore print. [4] [5]
Collybia personata is found fruiting in open grasslands, parks, pastures, forest clearings, and in the vicinity of forest edges, unlike Collybia nuda which is commonly found in woodland. Collybia personata fruits gregariously, forming distinctive fairy rings. [4] [5] Its fruiting season extends from summer to the beginning of winter, and is widespread in Europe. [4] In the UK, the season extends from September through to December.
It has also been allegedly reported from California in North America. [6] The California field blewit has also been described as Clitocybe tarda . [7]
Field blewits are edible. [8]
Blewits can be eaten as a cream sauce or sautéed in butter; they can also be cooked like tripe or as an omelette filling. [9]
Field blewits are often infested with fly larvae and don't store very well; they should therefore be used soon after picking. They are also very porous, so they are best picked on a dry day. [9]
Clitocybe is a genus of mushrooms characterized by white, off-white, buff, cream, pink, or light-yellow spores, gills running down the stem, and pale white to brown or lilac coloration. They are primarily saprotrophic, decomposing forest ground litter. There are estimated to be around 300 species in the widespread genus.
Tricholoma is a genus of fungus that contains many fairly fleshy white-spored gilled mushrooms which are found worldwide generally growing in woodlands. These are ectomycorrhizal fungi, existing in a symbiotic relationship with various species of coniferous or broad-leaved trees. The generic name derives from Ancient Greek: τριχο-, romanized: tricho-, lit. 'hair' and Ancient Greek: λῶμα, romanized: loma, lit. 'fringe, border' although only a few species have shaggy caps which fit this description.
Collybia nuda, commonly known as the blewit or wood blewit and previously described as Lepista nuda and Clitocybe nuda, is an edible mushroom native to Europe and North America. Described by Pierre Bulliard in 1790, it was also known as Tricholoma nudum for many years. It is found in both coniferous and deciduous woodlands. It is a fairly distinctive mushroom that is widely eaten. It has been cultivated in Britain, the Netherlands and France. This species was reassigned to the genus Collybia in 2023.
Blewit refers to two closely related species of edible agarics in the genus Collybia, the wood blewit and the field blewit or blue-leg.
Lepista is a genus of mushroom-forming fungi. According to the Dictionary of the Fungi, the widespread genus contains approximately 50 species. In 1969, Howard Bigelow and Alex H. Smith designated the group as subgenus of Clitocybe.
Agaricus augustus, known commonly as the prince, is a basidiomycete fungus of the genus Agaricus.
Clitocybe nebularis or Lepista nebularis, commonly known as the clouded agaric, cloudy clitocybe, or cloud funnel, is an abundant gilled fungus which appears both in conifer-dominated forests and broad-leaved woodland in Europe and North America. Appearing in Britain from mid to late autumn, it is edible, but may cause gastrointestinal issues.
Ampulloclitocybe clavipes, commonly known as the club-foot or club-footed clitocybe, is a species of gilled mushroom from Europe and North America. The grey brown mushrooms have yellowish decurrent gills and a bulbous stalk, and are found in deciduous and conifer woodlands. Although considered edible, disulfiram-like reactions have been reported after consumption of alcohol after eating this mushroom.
Aspropaxillus giganteus, also Leucopaxillus giganteus, commonly known as the giant leucopax or the giant funnel, is a saprobic species of fungus in the order Agaricales. As its common names imply, the fruit body, or mushroom, can become quite large—the cap reaches diameters of up to 50 cm (20 in). It has a white or pale cream cap, and is funnel-shaped when mature, with the gills running down the length of the stem. Considered by some to be a choice edible when young, this species has a cosmopolitan distribution, and is typically found growing in groups or rings in grassy pastures, roadside hedges, or woodland clearings. It has been shown to contain a bioactive compound with antibiotic properties.
Collybia is a genus of mushrooms in the family Tricholomataceae. The genus has a widespread but rare distribution in northern temperate areas, and contains three species that grow on the decomposing remains of other mushrooms.
Dendrocollybia is a fungal genus in the family Tricholomataceae of the order Agaricales. It is a monotypic genus, containing the single species Dendrocollybia racemosa, commonly known as the branched collybia or the branched shanklet. The somewhat rare species is found in the Northern Hemisphere, including the Pacific Northwest region of western North America, and Europe, where it is included in several Regional Red Lists. It usually grows on the decaying fruit bodies of other agarics—such as Lactarius and Russula—although the host mushrooms may be decayed to the point of being difficult to recognize.
Clitocybe glacialis is a species of mushroom in the family Tricholomataceae. Formerly known as Lyophyllum montanum, this is a snowbank mushroom, always associated with melting snow along snowbanks and thus glacialis. Originally described by Alexander H. Smith in 1957, this North American species is typically found growing under conifers on mountains.
Pholiota flammans, commonly known as the yellow pholiota, the flaming Pholiota, or the flame scalecap, is a basidiomycete agaric mushroom of the genus Pholiota. Its fruit body is golden-yellow in color throughout, while its cap and stem are covered in sharp scales. As it is a saprobic fungus, the fruit bodies typically appear in clusters on the stumps of dead coniferous trees. P. flammans is distributed throughout Europe, North America, and Asia in boreal and temperate regions. Its edibility has not been clarified.
Hygrophorus bakerensis, commonly known as the Mt. Baker waxy cap, the brown almond waxy cap or the tawny almond waxy cap, is a species of fungus in the family Hygrophoraceae. It is characterized by its medium to large, relatively slender-statured fruit bodies with an almond odor, and growth often on or near rotting conifer wood. The slimy cap is brown in the center and cream to white near its curved edges. The gills and the stem are white, and in moist environments are often covered with droplets of a translucent liquid. The mushroom is known only from the United States, where it is common in coniferous forests throughout the Pacific Northwest. It was initially collected in Washington State on Mount Baker, a volcano. Although edible, the mushroom is not considered to be of high quality.
Collybia cookei is a species of fungus in the family Tricholomataceae, and one of three species in the genus Collybia. It is known from Europe, Asia, and North America. The fungus produces fruit bodies that usually grow on the decomposing remains of other mushrooms, like Meripilus giganteus, Inonotus hispidus, or species of Russula; occasionally fruit bodies are found on rich humus or well-decayed wood. The fungus produces small white mushrooms with caps up to 9 mm (0.35 in) in diameter, supported by thin stems that originate from a yellowish-brown sclerotium. The mushroom is difficult to distinguish from the other two species of Collybia unless an effort is made to examine the sclerotia, which is usually buried in the substrate. The edibility of the mushroom has not been determined.
Collybia cirrhata is a species of fungus in the family Tricholomataceae of the order Agaricales. The species was first described in the scientific literature in 1786, but was not validly named until 1803. Found in Europe, Northern Eurasia, and North America, it is known from temperate, boreal, and alpine or arctic habitats. It is a saprobic species that grows in clusters on the decaying or blackened remains of other mushrooms. The fruit bodies are small, with whitish convex to flattened caps up to 11 mm in diameter, narrow white gills, and slender whitish stems 8–25 mm long and up to 2 mm (0.08 in) thick. C. cirrhata can be distinguished from the other two members of Collybia by the absence of a sclerotium at the base of the stem. The mushroom is of unknown edibility.
Clitocybe tarda is a species of mushroom. It has a brownish pink cap with a smooth surface, the flesh is thin and brittle, and the cap tastes bitter. The stalk is slender and smooth. The spore print is pinkish gray. It is unknown if the species is edible, but it does not have a pleasant taste.
Volvariella surrecta, commonly known as the piggyback rosegill, is an agaric fungus in the family Pluteaceae. Although rare, the species is widely distributed, having been reported from Asia, North America, Northern Africa, Europe, and New Zealand. The fungus grows as a parasite on the fruit bodies of other gilled mushrooms, usually Clitocybe nebularis. V. surrecta mushrooms have white or greyish silky-hairy caps up to 8 cm (3.1 in) in diameter, and white gills that turns pink in maturity. The stipe, also white, is up to 9 cm (3.5 in) long, and has a sack-like volva at its base.
Paralepista flaccida is a species of mushroom found across the Northern Hemisphere. It is known to form fairy rings.
Collybia brunneocephala, also known as the brown blewit or brownit, is a species of gilled mushroom. Previously designated Clitocybe brunneocephala, the brownit and its lavender-colored cousin the wood blewit were reassigned to the genus Collybia in 2023.
