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.
Clitocybe odora, commonly known as the blue green anise mushroom, or aniseed toadstool, is a blue-green mushroom that grows near deciduous and coniferous trees. They can be found growing in small groups along the side of tree roots. This mushroom is edible, but a few expert mushroom hunters insist that young specimens should be avoided as they can be confused with Stropharia aeruginosa. The anise odor is due to the presence of p-anisaldehyde and a small amount of benzaldehyde. This odor can give away the mushroom's presence before it is observed by eye.
Stropharia rugosoannulata, commonly known as the wine cap stropharia, "garden giant", burgundy mushroom, king stropharia, or wine-red stropharia, is an agaric of the family Strophariaceae native to Europe and North America. Unlike many other members of the genus Stropharia, it is regarded as a choice edible and is commercially cultivated.
The genus Stropharia is a group of medium to large agarics with a distinct membranous ring on the stipe. Well-known members of this genus include the edible Stropharia rugosoannulata and the blue-green verdigris agarics. Stropharia are not generally regarded as good to eat and there are doubts over the edibility of several species. However the species Stropharia rugosoannulata is regarded as prized and delicious when young, and is now the premier mushroom for outdoor bed culture by mycophiles in temperate climates.
Chlorophyllum molybdites, commonly known as the green-spored parasol, false parasol, green-spored lepiota and vomiter, is a widespread mushroom. Poisonous and producing severe gastrointestinal symptoms of vomiting and diarrhea, it is commonly confused with the shaggy parasol or shaggy mane, and is the most commonly misidentified poisonous mushroom in North America. Its large size and similarity to the edible parasol mushroom, as well as its habit of growing in areas near human habitation, are reasons cited for this. The nature of the poisoning is predominantly gastrointestinal.
Agaricus bitorquis, commonly known as torq, banded agaric, spring agaric, banded agaricus, urban agaricus, or pavement mushroom, is an edible white mushroom of the genus Agaricus, similar to the common button mushroom that is sold commercially. The name supersedes Agaricus rodmani.
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.
Hygrocybe coccinea, sometimes called the scarlet hood, scarlet waxcap or righteous red waxy cap, is a colourful member of the mushroom genusHygrocybe. These waxcaps are found across the Northern Hemisphere from China and Japan to Europe and North America. The small bright red mushroom is a familiar sight in unimproved grasslands in Europe in late summer and autumn, and woodlands in North America in winter.
Russula aeruginea, also known as the grass-green russula, the tacky green russula, or the green russula, is an edible Russula mushroom. Widely distributed in northern temperate regions, it is usually found under birch, mostly in pine forests. The very poisonous death cap can have a similar appearance, especially from above.
Leucoagaricus leucothites, commonly known as the smooth parasol, woman on motorcycle, ma'am on motorcycle, white dapperling, or white agaricus mushroom, is a species of agaric fungus. The species was originally described as Agaricus leucothites by Carlo Vittadini in 1835, and bears similarity to species of that genus. Solomon Wasser transferred it to Leucoagaricus in 1977. While sometimes regarded as edible, the species is suspected of being poisonous due to gastric-upset-causing toxins. It could also be confused with the deadly Amanita ocreata.
Stropharia ambigua, sometimes known as the questionable Stropharia, is a saprotrophic agaric mushroom, commonly fruiting in leaf litter and wood chips in the Pacific Northwest.
Cortinarius mucosus, commonly known as the orange webcap or the slimy cortinarius, is a species of mushroom in the family Cortinariaceae. In North America, the species is more commonly associated with northern coniferous forests. The specific epithet is derived from the Latin word mucosus, meaning mucus.
Lepiota castanea, commonly known as the chestnut dapperling or petite parasol, is a deadly poisonous, uncommon, gilled mushroom of the genus Lepiota in the order Agaricales. It is known to contain amatoxins and consuming this fungus can be a potentially lethal proposition. It was described by French mycologist Lucien Quélet in 1881.
Russula albidula is a species of mushroom in the genus Russula. The species, known in the vernacular as the boring white russula or the whitish brittlegill, is nondescript, with a small or medium dirty white fruit body, and a highly acrid taste. It is found in eastern North America.
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.
Tricholoma saponaceum, also known as the soap-scented toadstool, soapy tricholoma, soapy knight or soap tricholoma is an inedible mushroom found in woodlands in Europe and North America.
All That the Rain Promises, and More... is a wild mushroom identification and field guide by American mycologist David Arora and published in 1991 by Ten Speed Press in Berkeley, California. The book includes detailed descriptions of more than 200 edible and poisonous mushroom species, as well as recipes, stories, and information on uses of various species such as for dying hair and clothing or playing games. In the preface, Arora writes, "In leafing through these pages, you may wonder what all the 'fanciful,' 'foolish,' or (shudder) 'extraneous' material is doing in a factual guide. After all, it is the practical, hands-on, how-to-identify information that makes this book useful and gives it substance. But I ask: is it any stranger or less desirable to sprinkle the facts with flakes of fancy than it is to liven up solemn, substantial fare like potatoes with something fancier and more flavorful, like wild mushrooms?"
Amanita magniverrucata, commonly known as the pine cone amanita, or great pine jewel, is a species of agaric mushroom in the family Amanitaceae. First described scientifically by American mycologists Harry Delbert Thiers and Joseph Ammirati in 1982, it is mycorrhizal and associates with the tree Pinus radiata.
Stropharia caerulea, commonly known as the blue roundhead, is a species of mushroom forming fungus in the family Strophariaceae. It is a somewhat common species found in Europe and North America, where it grows as a saprophyte in meadows, roadsides, hedgerows, gardens, and woodchip mulch. S. caerulea was officially described to science in 1979, although it was known to be a distinct species for about two centuries before that. The scientific name Stropharia cyanea, as defined by Tuomikoski in 1953, and used by several later authors, is a synonym of S. caerulea.
Stropharia coronilla, commonly known as the garland roundhead or garland stropharia, is a species of mushroom native to Europe and North America. It is considered poisonous, and is sometimes mistaken for species of Agaricus.
