Turbinellus floccosus, commonly known as the scaly vase, or sometimes the shaggy, scaly, or woolly chanterelle, is a cantharelloid mushroom of the family Gomphaceae native to Asia and North America. It was known as Gomphus floccosus until 2011, [1] when it was found to be only distantly related to the genus's type species, G. clavatus . It was consequently transferred from Gomphus to Turbinellus . The orange-capped vase- or trumpet-shaped fruiting bodies may reach 30 cm (12 in) high and 30 cm (12 in) wide. The lower surface, the hymenium, is covered in wrinkles and ridges rather than gills or pores, and is pale buff or yellowish to whitish.
T. floccosus forms symbiotic (ectomycorrhizal) relationships with various types of conifer, growing in coniferous woodlands across Eastern Asia, from North Korea to Pakistan, and in North America, more frequently in the west, in late summer and autumn. Though mild-tasting, they generally cause gastrointestinal symptoms of nausea, vomiting and diarrhoea when consumed. T. floccosus is eaten by local people in northeastern India, Nepal and Mexico.
This species was first described as Cantharellus floccosus in 1834 by American mycologist Lewis David de Schweinitz, who reported it growing in beech woods in Mount Pocono, Pennsylvania. [2] Its specific epithet is derived from the Latin floccus, meaning "tuft, or flock, of wool". [3] In 1839, Miles Joseph Berkeley named a specimen from Canada as Cantharellus canadensis based on a manuscript by Johann Friedrich Klotzsch, noting its affinity to C. clavatus. [4] A large specimen collected in Maine by Charles James Sprague was described as Cantharellus princeps in 1859 by Berkeley and Moses Ashley Curtis. [5] In 1891, German botanist Otto Kuntze renamed Cantharellus canadensis as Trombetta canadensis, and C. floccosus as Merulius floccosus. [6] [lower-alpha 1]
Franklin Sumner Earle made C. floccosus the type species of the new genus Turbinellus in 1909, in which he placed two other North American species. He remarked that the three "constitute a striking and well-marked genus which seems to have more in common with the club-shaped species of Craterellus than with the following genus where they have always been placed." [8] This was not widely taken up, as Earle's new combination was not published validly according to nomenclatural rules. [9]
American mycologist Elizabeth Eaton Morse described Cantharellus bonarii in 1930. The type locality was General Grant National Park in Fresno County, California. [10] In 1945 C. floccosus and Morse's C. bonarii were transferred to Gomphus by Rolf Singer. [11] The generic name is derived from the Ancient Greek γομφος , gomphos, meaning "plug" or "large wedge-shaped nail". [12] Alex H. Smith treated the members of Gomphus as two sections—Gomphus and Excavatus—within Cantharellus in his 1947 review of chanterelles in western North America, as he felt there were no consistent characteristics that distinguished the genera. The shaggy chanterelle was placed in the latter section due to its scaly cap, lack of clamp connections and rusty-colored spores. [13] Roger Heim classified it in the genus Nevrophyllum, before E. J. H. Corner returned it to Gomphus in 1966. [14]
The genus Gomphus, along with several others in the Gomphaceae, was reorganized in the 2010s after molecular analysis confirmed that the older morphology-based classification did not accurately represent phylogenetic relationships. [14] [15] [16] Thus the genus Turbinellus was resurrected and the taxon became Turbinellus floccosus. Giachini also concluded G. bonarii was the same species. [14]
T. floccosus has been given the common names of scaly vase chanterelle, [17] scaly chanterelle, woolly chanterelle, [18] or shaggy chanterelle, [19] though it is more closely related to stinkhorns than true chanterelles. [20] In Nepal, in the Sherpa language, it is known as diyo chyau or khumbhe chyau, from the words diyo, meaning "oil lamp" and chyau, meaning "mushroom", as the fruit bodies have a shape similar to the local oil lamps. [21] In Mexico, it is known as corneta or trompeta , or by the indigenous words oyamelnanácatl ("fir mushroom", from Nahuatl oyametl "fir", and nanacatl "mushroom"), [22] tlapitzal (derived from tlapitzalli , Nahuatl for "trumpet") [22] or tlapitzananácatl in Tlaxcala. [23]
Adult fruit bodies are initially cylindrical, maturing to trumpet- or vase-shaped and reaching up to 30 cm (12 in) in height and width. [24] There is no clear demarcation between the cap and stipe. [13] The stipe can be up to 15 cm (6 in) tall and 6 cm (2+1⁄2 in) wide, though it tapers to a narrower base. It is solid in younger specimens, though is often hollowed out by insect larvae in older. [24] At higher elevations, two or three fruit bodies may arise from one stipe. Colored various shades of reddish- to yellowish-orange, the cap surface is broken into scales, with the spaces between more yellow and the scales themselves more orange. The most colorful specimens occur in warm humid weather. [13] Older specimens are often paler. [18]
The white flesh is fibrous and thick, though thins with age. [13] Somewhat brittle, it can sometimes turn brown when cut or bruised. The smell has been reported as indistinct or "earthy and sweet", and the taste "sweet and sour". [24] The spore-bearing undersurface is irregularly folded, forked or ridged rather than gilled and is pale buff or yellowish to whitish in color. [25] These ridges are up to 4 mm (1⁄8 in) high, [24] and are decurrent—they extend below and run down the cap's attachment to the stipe, though irregularly so. [13] The spore print is brownish, the spores ellipsoid with dimensions of 12.4–16.8 × 5.8–7.3 μm. [25] The spore surface is roughened with ornamentations that can be made visible under the microscope by staining with methyl blue. [26]
The fruit bodies can last for some considerable time, growing slowly over a month. Mushrooms in subalpine and alpine areas are typically heavy-set with a short stipe, their growth slower in the cold climate. This latter form is seen at lower altitudes in colder seasons. Smith gave this the name forma rainierensis. Conversely, mushrooms at low altitudes, such as in the redwood forests, can grow and expand rapidly with large caps that have prominent scales. Smith described a paler form with a solid stipe from the Sierra Nevada as forma wilsonii. [13] American mycologist R. H. Petersen described an olive-capped form that is otherwise identical to the typical form. [27] These forms are not recognised as distinct. [9]
The related Turbinellus kauffmanii , found in western North America, is similar-looking but has a pale brown cap. [20] Younger specimens of the latter species also have a pungent smell. [13] Turbinellus fujisanensis , found in Japan, is another lookalike that has smaller spores than T. floccosus. [28] Gomphus clavatus is superficially similar. [20]
The fungus appears to form symbiotic (ectomycorrhizal) relationships with various conifers including Douglas-fir (Pseudotsuga menziesii), fir (Abies) species such as momi fir ( Abies firma ), European silver fir ( A. alba ) and Khinghan fir ( A. nephrolepis ), pine (Pinus) species such as Pinus densiflora and western hemlock ( Tsuga heterophylla ). [24] [27] In Mexico, the fungus associates with Abies religiosa [29] —the mycorrhizal association between these two species has been synthesized under controlled laboratory conditions. [30] T. floccosus is more abundant in older stands of trees and places where there is more decomposed wood on the forest floor. [24]
The species occurs in coniferous forests in North America, particularly the western states in late summer and autumn. It is most abundant in rainy parts of the Pacific Northwest, [27] northern California and the Sierra Nevada. [18] It also occurs across Asia, having been recorded from Japan, [31] [32] North Korea, [33] China, [31] Tibet, [27] India, [34] Nepal and Pakistan. [13] [31] Turbinellus floccosus has been occasionally recorded from introduced conifer plantations in Australia. [35]
Turbinellus floccosus is poisonous to some people who eat it, but has been consumed without incident by others. [36] Nausea, vomiting and diarrhea may occur, though are sometimes delayed by up to 8–14 hours. A tricarboxylic acid known as α-tetradecylcitric acid may be responsible for the extreme gastrointestinal symptoms. [25] [37] Laboratory experiments showed it increased tone of guinea pig smooth muscle of the small bowel (ileum), and that when given to rats, it led to mydriasis, skeletal muscle weakness, and central nervous system depression. [37] Turbinellus floccosus contains more than double the amount of this acid than the related T. kauffmanii. [38]
Despite its toxicity, T. floccosus is one of the ten wild mushrooms most widely consumed by ethnic tribes in Meghalaya, northeast India, [39] and is highly regarded by the Sherpa people in the vicinity of Sagarmatha National Park in Nepal. [21] What is not known is whether the Indian populations of T. floccosus are nontoxic, or whether the local people have developed an immunity to it. [40] It is also enjoyed in Mexico. [23] American mycologist David Arora reported that some enjoyed it while he felt it had a strong sour taste. [18]
The fruit body of T. floccosus produces oxylipin (lipids generated by oxygenation of fatty acids) that are active against the fungal plant pathogens Colletotrichum fragariae , C. gloeosporioides , and C. acutatum . [41] Extracts of the fungus have shown in standard laboratory tests to have antimicrobial activity against several human pathogenic strains. [40] T. floccosus also contains the dicatechol spermidine derivative pistillarin, a compound that inhibits DNA damage by hydroxyl radicals generated by the Fenton reaction. [42] Pistillarin is responsible for the green color obtained when iron salts are applied to the fruit body surface. [26]
Chanterelle is the common name of several species of fungi in the genera Cantharellus, Craterellus, Gomphus, and Polyozellus. They are orange, yellow or white, meaty and funnel-shaped. On the lower surface, most species have rounded, forked folds that run almost all the way down the stipe, which tapers down from the cap. Many species emit a fruity aroma and often have a mildly peppery taste.
The Cantharellaceae are a family of fungi in the order Cantharellales. The family contains the chanterelles and related species, a group of fungi that superficially resemble agarics but have smooth, wrinkled, or gill-like hymenophores. Species in the family are ectomycorrhizal, forming a mutually beneficial relationship with the roots of trees and other plants. Many of the Cantharellaceae, including the chanterelle, the Pacific golden chanterelle, the horn of plenty, and the trumpet chanterelle, are not only edible, but are collected and marketed internationally on a commercial scale.
Cantharellus is a genus of mushrooms, commonly known as chanterelles, a name which can also refer to the type species, Cantharellus cibarius. They are mycorrhizal fungi, meaning they form symbiotic associations with plants. Chanterelles may resemble a number of other species, some of which are poisonous.
In mycology, a lamella, or gill, is a papery hymenophore rib under the cap of some mushroom species, most often agarics. The gills are used by the mushrooms as a means of spore dispersal, and are important for species identification. The attachment of the gills to the stem is classified based on the shape of the gills when viewed from the side, while color, crowding and the shape of individual gills can also be important features. Additionally, gills can have distinctive microscopic or macroscopic features. For instance, Lactarius species typically seep latex from their gills.
Craterellus is a genus of generally edible fungi similar to the closely related chanterelles, with some new species recently moved from the latter to the former. Both groups lack true gills on the underside of their caps, though they often have gill-like wrinkles and ridges.
Hygrophoropsis aurantiaca, commonly known as the false chanterelle, is a species of fungus in the family Hygrophoropsidaceae. It is found across several continents, growing in woodland and heathland, and sometimes on woodchips used in gardening and landscaping. Fruit bodies (mushrooms) are yellow–orange, with a funnel-shaped cap up to 8 cm across that has a felt-like surface. The thin, often forked gills on the underside of the cap run partway down the length of the otherwise smooth stipe. Reports on the mushroom's edibility vary – it is considered poisonous, but has historically been eaten in parts of Europe and the Americas.
Craterellus tubaeformis is an edible fungus, also known as the winter chanterelle, yellowfoot, winter mushroom, or funnel chanterelle. It was reclassified from Cantharellus, which has been supported by molecular phylogenetics.
Gomphus clavatus, commonly known as pig's ears or the violet chanterelle, is an edible species of fungus in the genus Gomphus native to Eurasia and North America. Described by Jacob Christian Schäffer in 1774, G. clavatus has had several name changes and many alternative scientific names, having been classified in the genus Cantharellus, though it is not closely related to them. The fruit body is vase- or fan-shaped with wavy edges to its rim, and grows up to 15–16 cm wide and 17 cm tall. The upper surface or cap is orangish-brown to lilac, while the lower spore-bearing surface, the hymenium, is covered in wrinkles and ridges rather than gills or pores, and is a distinctive purple color.
Polyozellus is a fungal genus in the family Thelephoraceae, a grouping of mushrooms known collectively as the leathery earthfans. Previously considered a monotypic genus, it now contains the Polyozellus multiplex species complex. The genus name is derived from the Greek poly meaning many, and oz, meaning branch. It is commonly known as the blue chanterelle, the clustered blue chanterelle, bluefan, or, in Alaska, the black chanterelle. The distinctive fruit body of this species comprises blue- to purple-colored clusters of vase- or spoon-shaped caps with veiny wrinkles on the undersurface that run down the length of the stem.
Polyozellus multiplex is a species complex of fungi first described in 1899. P. multiplex is commonly known as the blue chanterelle, the purple chanterelle, or, in Alaska, the black chanterelle. However, this mushroom is not closely related to true chanterelles. While this name used to refer to a group of species, it is now used to describe only one species that held onto the name P. multiplex. The fruiting bodies of this species are blue- to purple-colored clusters of vase- or spoon-shaped caps, with veiny wrinkles on the underside which run down the length of the stem. P. multiplex was considered the monotypic species of the genus Polyozellus until recent molecular research divided the P. multiplex species complex into five species. The genus name is derived from the Greek poly meaning many, and oz, meaning branch. The specific epithet multiplex means "in many pieces," referring to the compound nature of the fruiting body.
Cantharellus lateritius, commonly known as the smooth chanterelle, is a species of edible fungus in the mushroom family Cantharellaceae. The species has a complex taxonomic history, and has undergone several name changes since its first description by American mycologist Lewis David de Schweinitz in 1822. The fruit bodies of the fungus are brightly colored yellow to orange, and usually highly conspicuous against the soil in which they are found. At maturity, the mushroom resembles a filled funnel with the spore-bearing surface along the sloping outer sides. The texture of the fertile undersurface (hymenium) of the caps is a distinguishing characteristic of the species: unlike the well-known golden chanterelle, the hymenium of C. lateritius is much smoother.
Cantharellus formosus, commonly known as the Pacific golden chanterelle, is a fungus native to the Pacific Northwest region of North America. It is a member of the genus Cantharellus along with other popular edible chanterelles. It was distinguished from C. cibarius in the 1990s. It is orange to yellow, meaty and funnel-shaped. On the underside of the smooth cap, it has gill-like ridges that run down onto its stipe, which tapers down from the cap. The false gills often have a pinkish hue. It has a mild, sweet odor.
Cantharellus subalbidus, the white chanterelle, is a fungus native to western North America. It is a member of the genus Cantharellus along with other popular edible chanterelles. It is similar in appearance to other chanterelles except for its cream to white color and orange bruising.
Cantharellus californicus, also called the California golden chanterelle, mud puppy, or oak chanterelle, is a fungus native to California, United States. It is a member of the genus Cantharellus along with other popular edible chanterelles. It is generally similar in appearance to C. cibarius and C. formosus except for its large size at maturity.
Cantharellus cascadensis, commonly known as the cascade chanterelle or hybrid chanterelle, is a fungus native to the Pacific Northwest region of North America. It is considered a choice edible mushroom.
Turbinellus is a genus of five species of fungi in the family Gomphaceae.
Turbinellus kauffmanii, commonly known as the scaly vase false chanterelle, is a species of mushroom native to North America.
Turbinellus stereoides, previously known as Gomphus stereoides, is a mushroom in the family Gomphaceae. It was originally described in 1996 by E. J. H. Corner as a species of Gomphus. The type collection was made in 1930 in Slim River, Malaysia.
Turbinellus fujisanensis, previously known as Gomphus fujisanensis, is a mushroom in the family Gomphaceae. It was originally described in 1941 by Sanshi Imai as a species of Cantharellus. Admir Giachini transferred it to Turbinellus in 2011. The genus Gomphus, along with several others in the Gomphaceae, was reorganized in the 2010s after molecular analysis confirmed that the older morphology-based classification did not accurately represent phylogenetic relationships.
Gloeocantharellus purpurascens, commonly known as the Indian Creek mushroom or violet-staining chanterelle, is a species of fungus in the family Gomphaceae native to North America and French Guiana.
