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.
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.
Leratiomyces ceres, commonly known as the chip cherry or redlead roundhead, is mushroom which has a bright red to orange cap and dark purple-brown spore deposit. It is usually found growing gregariously on wood chips and is one of the most common and most distinctive mushrooms found in that habitat. It is common on wood chips and lawns in North America, Europe, Australia, New Zealand and elsewhere. The name Stropharia aurantiaca has been used extensively but incorrectly for this mushroom.
Stropharia aeruginosa, commonly known as the blue-green stropharia, or verdigris agaric, is a medium-sized green, slimy woodland mushroom, found on lawns, mulch and woodland from spring to autumn. The edibility of this mushroom is controversial - some sources claim that it is edible, while others claim it to be poisonous, although effects are little known and its toxic constituents undescribed.
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.
Leccinum manzanitae is an edible species of bolete fungus in the family Boletaceae. Described as new to science in 1971, it is commonly known as the manzanita bolete for its usual mycorrhizal association with manzanita trees. Its fruit bodies (mushrooms) have sticky reddish to brown caps up to 20 cm (8 in), and its stipes are up to 16 cm (6.3 in) long and 3.5 cm (1.4 in) thick. They have a whitish background color punctuated with small black scales known as scabers. Found only in the Pacific Northwest region of the United States and Canada, it is the most common Leccinum species in California. The mushroom is edible, although opinions vary as to its quality. L. manzanitae can be usually distinguished from other similar bolete mushrooms by its large size, reddish cap, dark scabers on a whitish stipe, and association with manzanita and madrone.
Caloboletus rubripes, commonly known as the red-stipe bolete or the red-stemmed bitter bolete, is a mushroom in the family Boletaceae. It was known as Boletus rubripes until 2014. Fruit bodies (mushrooms) are robust, with caps up to 18 cm in diameter, atop thick stipes 5–12 cm long. Mushrooms are non-toxic, but is so bitter as to be inedible. The mushroom flesh has a very strong bluing reaction when cut or damaged. and forms mycorrhizal relationships, primarily with conifers. It can be differentiated from similar boletes by its cap color and non-reticulate stipe.
Xeromphalina campanella is a species of mushroom. The common names of the species include the golden trumpet and the bell Omphalina. The genus name Xeromphalina means "little dry navel" and campanella means "bell-shaped", respectively describing the mature and young shapes of the pileus, or cap. The mushroom is also called fuzzy-foot.
Suillus tomentosus is a species of mushroom. The common names of the species are blue-staining slippery Jack, poor man's slippery Jack, and woolly-capped suillus.
Cortinarius traganus, also known as the gassy webcap or lilac conifer cortinarius, is a basidiomycete mushroom of the genus Cortinarius. The mushrooms are characterized by their lilac color, the rusty-brown gills and spores, and rusty-brown flesh in the stem.
Boletus fibrillosus is a basidiomycete fungus of the genus Boletus found in western North America. The fruiting bodies are found in mixed coastal forests in the fall, usually singly or in small groups. The cap is up to 17 cm wide, buff to brown to dark brown in color, and has a wrinkled to finely fibrous texture. The tubes are yellow, while the flesh is white to buff and does not stain when cut. The stem is yellowish at the top, brown otherwise, with a reticulate texture, and mycelium enshrouding the bottom. The holotype was collected in Mendocino County, California. The species is edible, but considered to have inferior taste to other edible boletes such as B. edulis, which it is often confused with.
Pholiota aurivella, commonly known as the golden pholiota, is a species of fungus in the family Strophariaceae that is found in native forest of New Zealand, southern Canada, and in the United States. It is frequently found in the American West and Southwest, especially in late summer and fall. Most field guides list it as inedible, with one reporting that it contains toxins which cause gastric upset. According to David Arora, the taste resembles "marshmallows without the sugar." It is sticky or slimy when moist and grows in clusters on live or dead trees.
Protostropharia semiglobata, commonly known as the dung roundhead, the halfglobe mushroom, or the hemispherical stropharia, is an agaric fungus of the family Strophariaceae. A common and widespread species with a cosmopolitan distribution, the fungus produces mushrooms on the dung of various wild and domesticated herbivores. The mushrooms have hemispherical straw yellow to buff-tan caps measuring 1–4 cm (0.4–1.6 in), greyish gills that become dark brown in age, and a slender, smooth stem 3–12 cm (1.2–4.7 in) long with a fragile ring.
Leccinum insigne, commonly known as the aspen bolete or the aspen scaber stalk, is a species of bolete fungus in the family Boletaceae. Described as new to science in 1966, it is found in North America, where its range extends from eastern Canada south to New Jersey and west to the northern Rocky Mountains. It is a good edible mushroom, but there have been documented cases of adverse reactions; these range from headaches to gastrointestinal distress, which may or may not be attributed to food sensitivities alone. The specific epithet insigne means "distinctive or outstanding".
Amanita pachycolea, commonly known as the western grisette or the Stuntz's great ringless amanita, is a species of agaric fungus in the family Amanitaceae.
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.
Pholiota astragalina, commonly known as the pinkish-orange pholiota, is a species of fungus in the family Strophariaceae. It was first described scientifically in 1821 by Elias Magnus Fries as a species of Agaricus. Rolf Singer transferred it to the genus Pholiota in 1951. The fruitbodies of the fungus have pinkish-orange caps measuring 2–5.5 cm in diameter. The flesh is orange, blackening in age, with a bitter taste. They produce a reddish-brown spore print, causing it to be placed in its genus rather than Hypholoma, which it resembles. The spores are oval to elliptical, smooth with thin walls, and measure 5–7 by 4–4.5 µm. In North America, the fungus is found in the United States and Canada. In Europe, it has been recorded from France, Sweden, and Switzerland. Its mushrooms usually grow singly or in small clusters, sometimes on conifer logs.
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.
Phlebia tremellosa, commonly known as trembling Merulius or jelly rot, is a species of fungus in the family Meruliaceae. It is a common and widely distributed wood-decay fungus that grows on the rotting wood of both hardwood and conifer plants.
