In mycology, a partial veil is a temporary structure of tissue found on the fruiting bodies of some basidiomycete fungi, typically agarics. Its role is to isolate and protect the developing spore-producing surface, represented by gills or tubes, found on the lower surface of the cap. A partial veil, in contrast to a universal veil, extends from the stem surface to the cap edge. The partial veil later disintegrates, once the fruiting body has matured and the spores are ready for dispersal. It might then give rise to a stem ring, or fragments attached to the stem or cap edge. In some mushrooms, both a partial veil and a universal veil may be present.
Cryptoporus volvatus, commonly known as the veiled polypore or cryptic globe fungus, is a polypore fungus that decomposes the rotting sapwood of conifers. It is an after effect of attack by the pine bark beetle. The fungus was originally described by American mycologist Charles Horton Peck in 1875 as Polyporus volvatus. Cornelius Lott Shear transferred it to the genus Cryptoporus in 1902. The species is inedible.
Agaricus bernardii, commonly called the salt-loving agaricus, or salty mushroom, is an agaric fungus in the family Agaricaceae. The mushroom's thick stem is usually shorter than the diameter of the cap, which ranges from 5–15 centimetres and is convex to flattened. The cap surface is whitish to buff, and can develop scales or warts in age. The gills are initially pink before turning brown when the spores mature. The flesh turns reddish when it is cut or bruised. It resembles species such as A. bitorquis.
Agaricus silvicola, also known as the wood mushroom or woodland agaricus, is a species of Agaricus mushroom related to the button mushroom. A. silvicola is a member of Agaricus section Arvenses, a group of morphologically similar mushrooms. A. silvicola, like other species in Agaricus section Arvenses, exhibits a positive Schäffer's reaction and potassium hydroxide reaction, and smells of almonds or anise.
Calostoma is a genus of 29 species of gasteroid fungi in the suborder Sclerodermatineae. Like other gasteroid fungi, Calostoma do not have the spore discharge mechanism associated with typical gilled fungi (ballistospory), and instead have enclosed spore-bearing structures. Resembling round puffballs with raised, brightly colored spore openings (ostioles), elevated on a thick, gelatinous stalks, species have been collected in regions of deciduous, temperate, tropical or subtropical forests. Their distribution includes eastern North America, Central America, Asia, and Australasia. The common name given to some species, "prettymouth", alludes to the brightly colored raised openings (ostioles) that may somewhat resemble lips. Other common names include "hotlips" and "puffball in aspic".
Geastrum saccatum, commonly known as the sessile earthstar or rounded earthstar, or star of the land, is a species of mushroom belonging to the genus Geastrum. The opening of the outer layer of the fruiting body in the characteristic star shape is thought to be due to a buildup of calcium oxalate crystals immediately prior to dehiscence. G. saccatum is distinguished from other earthstars by the distinct circular ridge or depression surrounding the central pore.
Astraeus hygrometricus, commonly known as the hygroscopic earthstar, the barometer earthstar, or the false earthstar, is a species of fungus in the family Diplocystaceae. Young specimens resemble a puffball when unopened. In maturity, the mushroom displays the characteristic earthstar shape that is a result of the outer layer of fruit body tissue splitting open in a star-like manner. The false earthstar is an ectomycorrhizal species that grows in association with various trees, especially in sandy soils. A. hygrometricus was previously thought to have a cosmopolitan distribution, though it is now thought to be restricted to Southern Europe, and Astraeus are common in temperate and tropical regions. Its common names refer to the fact that it is hygroscopic (water-absorbing) and can open up its rays to expose the spore sac in response to increased humidity, then close them up again in drier conditions. The rays have an irregularly cracked surface, while the spore case is pale brown and smooth with an irregular slit or tear at the top. The gleba is white initially, but turns brown and powdery when the spores mature. The spores are reddish-brown and roughly spherical with minute warts, measuring 7.5–11 micrometers in diameter.
Astraeus is a genus of fungi in the family Diplocystaceae. The genus, which has a cosmopolitan distribution, contains nine species of earthstar mushroom. They are distinguished by the outer layer of flesh (exoperidium) that at maturity splits open in a star-shape manner to reveal a round spore sac. Additionally, they have a strongly hygroscopic character—the rays will open when moist, but when hot and dry will close to protect the spore sac. Species of Astraeus grow on the ground in ectomycorrhizal associations with trees and shrubs. Despite their similar appearance to the Geastrum earthstars Astraeus is not closely related.
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, 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.
Geastrum triplex is a fungus found in the detritus and leaf litter of hardwood forests around the world. It is commonly known as the collared earthstar, the saucered earthstar, or the triple earthstar—and less commonly by the alternative species name Geastrum indicum. It is the largest member of the genus Geastrum and expanded mature specimens can reach a tip-to-tip length of up to 12 centimeters.
Gastropila fumosa is a species of puffball in the family Agaricaceae. It was first described as Calvatia fumosa by American mycologist Sanford Myron Zeller in 1947, and later transferred to Gastropila in 1976. Some authors place it instead in the genus Handkea, circumscribed by Hanns Kreisel in 1989.
Amanita franchetii, also known as the yellow veiled amanita, or Franchet's amanita, is a species of fungus in the family Amanitaceae.
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.
Myriostoma coliforme, commonly known as the saltshaker earthstar or pepper pot, is a fungal species in the family Geastraceae. Basidiocarps resemble earthstars, but the spore sac is supported by multiple columns and has multiple ostioles instead of a single, apical ostiole. It has also been called "salt-shaker earthstar". The fungus has a north temperate distribution, but was formerly thought to be more widespread due to confusion with related Myriostoma species. Myriostoma coliforme is an uncommon species and appears on the Red Lists of 12 European countries. In 2004 it was one of 33 species proposed for protection under the Bern Convention by the European Council for Conservation of Fungi.
Montagnea arenaria, commonly known as the gasteroid coprinus, is a species of secotioid fungus in the family Agaricaceae. Originally named Agaricus arenarius by Augustin Pyramus de Candolle in 1815, it was transferred to the genus Montagnea by Sanford Myron Zeller in 1943. The species is characterized by a cap that has an apical disc, radial gills, a hymenophore, and spores with a prominent germ pore. It is inedible.
Suillus ochraceoroseus, commonly known as the rosey larch bolete, is a species of mushroom in the genus Suillus. It appears with larch in early summer, is edible, and similar in appearance to S. lakei.
Agaricus inapertus, commonly known as the mountain gasteroid agaricus, is a species of secotioid fungus in the genus Agaricus. It was first described by American mycologists Rolf Singer and Alexander H. Smith in 1958 as Endoptychum depressum. Molecular analysis later proved it to be aligned with Agaricus, and it was formally transferred in a 2003 publication.
Boletus subalpinus, commonly known as the gasteroid king bolete, is a species of fungus in the family Boletaceae. The species was first described scientifically in 1969 by American mycologists Harry Delbert Thiers and James M. Trappe. It is found in California and Oregon. It was originally named as a species of Gastroboletus but was found to be in Boletus sensu stricto in a 2013 molecular phylogenetics study.
Gomphidius subroseus, commonly known as the rosy gomphidius is a gilled mushroom found in Europe and North America. It was first described by Calvin Henry Kauffman in 1925. It was once thought to be mycorrhizal with Pinus sylvestris. However, Olson et al. (2002) found it to be more likely to be parasitic on Suillus bovinus, which is mycorrhizal with Pinus sylvestris, Pinus sylvestris or both. It is considered edible but of low quality. As with other species of the genus, removing the glutinous cuticle improves the taste.
Cortinarius sanguineus, commonly known as the blood red webcap or blood red cortinarius, is a species of fungus in the genus Cortinarius.
