Hypomyces cervinigenus is a parasitic ascomycete fungus that grows on elfin saddle ( Helvella ) mushrooms in Europe and North America.
The species was described as new to science in 1971 by Clark Rogerson and Horace Simms. The type collection was made in Pierce County, Washington, where the fungus was found growing on the stipe and cap of what they identified as a fruit body of Helvella lacunosa . (Later molecular work demonstrated that the European H. lacunosa is not found in North America, and that the corresponding species are H. dryophila and H. vespertina .) [1]
H. cervinigenus has perithecia that are white to pale buff with a waxy texture. The ascospores are two-celled, smooth-walled, and measure less than 25 µm long. [2] The anamorph form of the fungus is known as Mycogone cervina. [3]
H. cervinigenus can be found growing on elfin saddle ( Helvella ) mushrooms in Europe and North America.
Hypomyces lactifluorum, the lobster mushroom, contrary to its common name, is neither a mushroom nor a crustacean, but rather a parasitic ascomycete fungus that grows on certain species of mushrooms, turning them a reddish orange color that resembles the outer shell of a cooked lobster. H. lactifluorum specifically attacks members of the genera Lactarius and Lactifluus (milk-caps), and Russula (brittlegills), such as Russula brevipes and Lactifluus piperatus in North America. At maturity, H. lactifluorum thoroughly covers its host, rendering it unidentifiable. Lobster mushrooms are widely eaten and enjoyed freshly foraged and cooked. They are commercially marketed and sometimes found in grocery stores; they have been made available at markets in Oregon. They have a seafood-like flavor and a firm, dense texture.
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.
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.
Gyromitra is a genus of about 18 species of ascomycete fungi. They are a false morel - a frequently toxic mushroom that can be mistaken for edible mushrooms of the genus Morchella (morels).
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.
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.
Chorioactis is a genus of fungi that contains the single species Chorioactis geaster. The mushroom is commonly known as the devil's cigar or the Texas star in the United States, while in Japan it is called kirinomitake (キリノミタケ). This extremely rare mushroom is notable for its unusual appearance and disjunct distribution; it is found only in select locales in Texas and Japan. The fruit body, which grows on the stumps or dead roots of cedar elms or dead oaks, somewhat resembles a dark brown or black cigar before it splits open radially into a starlike arrangement of four to seven leathery rays. The interior surface of the fruit body bears the spore-bearing tissue known as the hymenium, and is colored white to brown, depending on its age. The fruit body opening can be accompanied by a distinct hissing sound and the release of a smoky cloud of spores.
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.
Suillus spraguei is a species of fungus in the family Suillaceae. It is known by a variety of common names, including the painted slipperycap, the painted suillus or the red and yellow suillus. Suillus spraguei has had a complex taxonomical history, and is also frequently referred to as Suillus pictus in the literature. The readily identifiable fruit bodies have caps that are dark red when fresh, dry to the touch, and covered with mats of hairs and scales that are separated by yellow cracks. On the underside of the cap are small, yellow, angular pores that become brownish as the mushroom ages. The stalk bears a grayish cottony ring, and is typically covered with soft hairs or scales.
Hypomyces chrysospermus, the bolete eater, is a parasitic ascomycete fungus that grows on bolete mushrooms, turning the afflicted host a whitish, golden yellow, or tan color. It is found in Eurasia and North America, as well as southwest Western Australia.
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.
Xylobolus frustulatus, commonly known as the ceramic fungus or ceramic parchment, is an inedible species of crust fungus in the Stereaceae family. The fruit body forms small, hard, flat crust-like aggregations that resemble broken pieces of ceramic tile. These pieces are initially whitish before turning yellow-brown to gray-brown in age. The spore-bearing cells cover the upper surfaces of the fruit body. A saprobic species, it grows on well-decayed oak wood in Asia, northern Europe, and North America.
Clark Thomas Rogerson,, was an American mycologist. He was known for his work in the Hypocreales (Ascomycota), particularly Hypomyces, a genus of fungi that parasitize other fungi. After receiving his doctorate from Cornell University in 1950, he went on to join the faculty of Kansas State University. In 1958, he became a curator at The New York Botanical Garden, and served as editor for various academic journals published by the Garden. Rogerson was involved with the Mycological Society of America, serving in various positions, including president in 1969. He was managing editor (1958–89) and editor-in-chief (1960–65) of the scientific journal Mycologia.
Glutinoglossum is a genus of six species of earth-tongue fungi in the family Geoglossaceae. The widespread type species, G. glutinosum, is commonly known as the "glutinous earth tongue". G. heptaseptatum is known only from the Czech Republic. Four additional species were described in 2015.
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 completus is a parasitic ascomycete in the order Hypocreales. The fungus grows on boletes, typically Suillus spraguei in North America, although the type collection was found on growing on Boletinus oxydabilis in Siberia. The color of its subiculum ranges from white initially to yellow-brown to greenish-brown to brown to black; the fruitbodies (perithecia) range from pale brown to dark brown to black. Spores measure 35–40 by 4–6 μm.
Hypomyces lateritius is a parasitic ascomycete fungus that grows on certain species of Lactarius mushrooms, improving their flavor and densifying the flesh. Hosts include L. camphoratus, L. chelidonium, L. controversus,L. deliciosus, Lactarius indigo, L. rufus, L. salmonicolor, L. sanguifluus, L. semisanguifluus, L. tabidus, L. trivialis, and L. vinosus.
