Helvella crispa, also known as the white saddle, elfin saddle or common helvel, is an ascomycete fungus of the family Helvellaceae. The mushroom is readily identified by its irregularly shaped whitish cap, fluted stem, and fuzzy undersurfaces. It is found in eastern North America and in Europe, near deciduous trees in summer and autumn.
The fungus was originally described as Phallus crispus by the naturalist Giovanni Antonio Scopoli in 1772. [1] Its specific epithet is Latin adjective crispa 'wrinkled' or 'curly'. The generic name was originally a type of Italian herb but became associated with morels. [2]
Helvella crispa is creamy white in colour, 6–13 cm (2½–5 in) in length, with a cap 2–5 cm (1–2 in) in diameter. It is striking due to its irregularly shaped lobes on the cap, but with a robust creamy-white base (2–8×1–2.5 cm in size). Its flesh is thin and brittle. The stem is 3–10 cm (1¼–4 in) long, white or pinkish in colour and ornately ribbed. It gives off a pleasant aroma, but is not edible raw. The spore print is white, the oval spores average 19 x 11.5 μm. [3] Occasionally white capped forms are found. It can be distinguished from occasional white forms of Helvella lacunosa by its furry cap undersurface and inrolled margins when young. [4]
Helvella crispa grows in grass as well as in humid hardwoods, such as beech, (not so well in resinous ones) along the side of pathways, in hedges and on the talus of meadows. They can be spotted from the end of summer until the end of autumn. [5]
It is found in China, [6] Japan, [7] Europe and eastern North America, though is replaced by the related Helvella lacunosa in western parts. [8]
Although some guidebooks list this species as edible, [3] [5] there is speculation that it may contains monomethylhydrazine, which can cause severe intoxication, and may be carcinogenic.[ citation needed ] It has been reported to cause gastrointestinal symptoms when eaten raw. [4]
Also recent evidence suggests that this fungus and similar species may cause the potentially fatal disease amyotrophic lateral sclerosis (ALS) after many years or even decades. [9] [10]
Laccaria laccata, commonly known as the deceiver, lackluster laccaria, or waxy laccaria, is a white-spored species of small edible mushroom found throughout North America and Europe. It is a highly variable mushroom, and can look quite washed out, colorless and drab, but when younger it often assumes red, pinkish brown, and orange tones. The species is often considered by mushroom collectors to be a 'mushroom weed' because of its abundance and plain stature.
Macrolepiota procera, the parasol mushroom, is a basidiomycete fungus with a large, prominent fruiting body resembling a parasol. It is a fairly common species on well-drained soils. It is found solitary or in groups and fairy rings in pastures and occasionally in woodland. Globally, it is widespread in temperate regions.
Hypomyces is a genus of parasitic ascomycete fungi found in Europe, North America, Australia, and parts of China. The genus contains 53 species. Better known species include the lobster mushroom and the bolete eater.
Sarcoscypha coccinea, commonly known as the scarlet elf cup, scarlet elf cap, or the scarlet cup, is a species of fungus in the family Sarcoscyphaceae of the order Pezizales. The fungus, widely distributed in the Northern Hemisphere, has been found in Africa, Asia, Europe, North and South America, and Australia. The type species of the genus Sarcoscypha, S. coccinea has been known by many names since its first appearance in the scientific literature in 1772. Phylogenetic analysis shows the species to be most closely related to other Sarcoscypha species that contain numerous small oil droplets in their spores, such as the North Atlantic island species S. macaronesica. Due to similar physical appearances and sometimes overlapping distributions, S. coccinea has often been confused with S. occidentalis, S. austriaca, and S. dudleyi.
Gyromitra infula, commonly known as the hooded false morel or the elfin saddle, is a fungus in the family Helvellaceae. The dark reddish-brown caps of the fruit bodies develop a characteristic saddle-shape in maturity, and the ends of both saddle lobes are drawn out to sharp tips that project above the level of the fruit body. The stipe is white or flushed pale brown, smooth on the outside, but hollow with some chambers inside. It is found in the Northern Hemisphere, usually in the late summer and autumn, growing on rotting wood or on hard packed ground. G. infula is considered inedible as it contains the toxic compound gyromitrin which, when metabolized by the body, is converted into monomethylhydrazine, a component of some rocket fuels. The toxin may be removed by thorough cooking. Gyromitra fungi are included in the informal category "false morels".
Helvella is a genus of ascomycete fungus of the family Helvellaceae. The mushrooms, commonly known as elfin saddles, are identified by their irregularly shaped caps, fluted stems, and fuzzy undersurfaces. They are found in North America and in Europe. Well known species include the whitish H. crispa and the grey H. lacunosa. They have been reported to cause gastrointestinal symptoms when eaten raw.
Gyromitra caroliniana, known commonly as the Carolina false morel or big red, is an ascomycete fungus of the genus Gyromitra, within the Pezizales group of fungi. It is found in hardwood forests of the southeastern United States, where it fruits in early spring soon after snowmelt.
The common name elfin saddle is given to a number of Ascomycete fungi in the order Pezizales. These medium to small fungi often have irregular saddle-shaped caps. Species include:
Helvella lacunosa, known as the slate grey saddle or fluted black elfin saddle in North America, simply as the elfin saddle in Britain, is an ascomycete fungus of the family Helvellaceae. It is one of the most common species in the genus Helvella. The mushroom is readily identified by its irregularly shaped grey cap, fluted stem, and fuzzy undersurfaces. It is usually found in Eastern North America and in Europe, near deciduous and coniferous trees in summer and autumn.
Lactifluus piperatus, commonly known as the blancaccio, is a semi-edible basidiomycete fungus of the genus Lactifluus. Despite being edible, it is not recommended by some because of its poor taste, though can be used as seasoning when dried. The fruiting body is a creamy-white mushroom which is funnel-shaped when mature, with exceptionally crowded gills. It bleeds a whitish peppery-tasting milk when cut. Widely distributed across Europe and eastern North America, Lactifluus piperatus has been accidentally introduced to Australia. Mycorrhizal, it forms a symbiotic relationship with various species of deciduous tree, including beech, and hazel, and fruiting bodies are found on the forest floor in deciduous woodland.
Helvella acetabulum is a species of fungus in the family Helvellaceae, order Pezizales. This relatively large cup-shaped fungus is characterized by a tan fruit body with prominent branching ribs resembling a cabbage leaf; for this reason it is commonly known as the cabbage leaf Helvella. Other colloquial names include the vinegar cup and the brown ribbed elfin cup. The fruit bodies reaches dimensions of 8 cm (3.1 in) by 4 cm (1.6 in) tall. It is found in Asia, Europe, and North America, where it grows in sandy soils, under both coniferous and deciduous trees.
Helvella corium is a species of fungus in the family Helvellaceae of the order Pezizales. This inedible cup-shaped fungus is black, and grows on the ground often near willows in deciduous or mixed forests.
Helvella elastica, commonly known as the flexible Helvella, or the elastic saddle, is a species of fungus in the family Helvellaceae of the order Pezizales. It is found in Asia, Europe, and North America. It has a roughly saddle-shaped yellow-brown cap atop a whitish stipe, and grows on soil in woods. Another colloquial name is the brown elfin saddle.
Dissingia leucomelaena, commonly known as the white-footed elf cup, is a species of fungus in the family Helvellaceae of the order Pezizales. As its common name implies, it is characterized by the white coloring of its stem.
Helvella macropus is a species of fungus in the family Helvellaceae of the order Pezizales. Ascocarps are found in summer and autumn in woodland, usually associated with broad-leaved trees.
Helvella ephippium is a species of fungus in the family Helvellaceae, Pezizales order. It appears in summer and autumn as an upright white stem up to 5 centimetres tall supporting a greyish-brown saddle-shaped cap. It is found in woodland and is variously listed as inedible or "edible but uninspiring".
Strobilomyces strobilaceus, also called Strobilomyces floccopus and commonly known as old man of the woods, is a species of fungus in the family Boletaceae. It is native to Europe and North America. Fruit bodies are characterized by very soft dark grey to black pyramidal and overlapping scales on the cap surface.
Leotia lubrica, commonly referred to as a jelly baby, is a species of fungus in the family Leotiaceae. The species produces small fruit bodies up to 6 centimetres (2.4 in) in height, featuring a "head" and a stalk. Ochre with tints of olive-green, the heads are irregularly shaped, while the stalk, of a similar colour, attaches them to the ground. The appearance can be somewhat variable and is similar to a number of other species, including Cudonia confusa, C. circinans, L. atrovirens and L. viscosa. L. lubrica was first validly described by Giovanni Antonio Scopoli, but it was later transferred to Leotia by Christiaan Hendrik Persoon. Its relationship with other members of the genus, of which it is the type species, is complicated.
Helvella vespertina is a species of fungus in the family Helvellaceae. It is found in Western North America under conifers. Some specimens have a white moldy appearance, having been colonised by the parasitic Ascomycete fungus Hypomyces cervinigenus.
Hypomyces cervinigenus is a parasitic ascomycete fungus that grows on elfin saddle (Helvella) mushrooms in Europe and North America.
