Gastroboletus amyloideus is a species of fungus in the family Boletaceae. The species was first described scientifically in 1969 by American mycologist Harry Delbert Thiers. Characterized by its amyloid spore staining reaction, the fungus is found in California. [1]
Alexander Hanchett Smith was an American mycologist known for his extensive contributions to the taxonomy and phylogeny of the higher fungi, especially the agarics.
Gymnopilus luteoviridis is a widely distributed mushroom-forming fungus of the Eastern United States that contains the hallucinogens psilocybin and psilocin.
Gastroboletus is a genus of fungi in the family Boletaceae. Species in the genus have misshapen caps, poorly developed or absent stipes, and are often buried or partially buried. Gastroboletus has tubes arranged irregularly, rather than vertically as in typical boletes. The edibility of most species is unknown, and those known to be edible are not highly rated.
Gastroleccinum is a fungal genus in the family Boletaceae. It is a monotypic genus, represented by the single species Gastroleccinum scabrosum. The genus was circumscribed by Harry Delbert Thiers in 1989.
Gymnogaster is a genus of fungi in the family Boletaceae. It is a monotypic genus, containing the single secotioid species Gymnogaster boletoides, found in Australia. The fungus produces bright yellow fruit bodies with a light brown internal gleba, and the fruit bodies turn blue then dark brown after bruising or handling.
Boletus regineus, commonly known as the queen bolete, is an edible and highly regarded fungus of the genus Boletus that inhabits southwestern North America. It was considered a variant of the similarly edible B. edulis for many years until declared a unique species in 2008. Phylogenetic analysis has shown B. regineus as a member of a clade, or closely related group, with B. subcaerulescens, Gastroboletus subalpinus, B. pinophilus, B. fibrillosus, and B. rex-veris.
Suillus pungens, commonly known as the pungent slippery jack or the pungent suillus, is a species of fungus in the genus Suillus. The fruit bodies of the fungus have slimy convex caps up to 14 cm (5.5 in) wide. The mushroom is characterized by the very distinct color changes that occur in the cap throughout development. Typically, the young cap is whitish, later becoming grayish-olive to reddish-brown or a mottled combination of these colors. The mushroom has a dotted stem (stipe) up to 7 cm (2.8 in) long, and 2 cm (0.8 in) thick. On the underside on the cap is the spore-bearing tissue consisting of minute vertically arranged tubes that appear as a surface of angular, yellowish pores. The presence of milky droplets on the pore surface of young individuals, especially in humid environments, is a characteristic feature of this species. S. pungens can usually be distinguished from other similar Suillus species by differences in distribution, odor and taste. The mushroom is considered edible, but not highly regarded.
Saproamanita thiersii, commonly called Thiers' lepidella, is a North American saprotrophic basidiomycete fungus in the genus Saproamanita. It is a white, small mushroom. Its cap is convex, measuring 3.5–10 centimetres across, and the stipe is 8–20 cm (3–8 in) long. The spore print is white.
Omphalotus olivascens, commonly known as the western jack-o'-lantern mushroom, is an orange to brown-colored gilled poisonous mushroom native to California and Mexico. It is sometimes mistaken for chanterelles.
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.
Boletus subcaerulescens is a basidiomycete fungus of the genus Boletus found in northeastern North America. The fruiting bodies are found associated with pine and spruce. The cap is up to 18 cm wide, convex to flat, and brown in color. The tubes are yellow and stain blue when bruised, while the flesh is white to buff and does not stain when cut. The stem is brown like the cap and has a light-colored reticulate texture.
Boletus subalpinus 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.
Gastroboletus xerocomoides 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 Trappe. It is found in California, usually near Red Fir trees.
Pluteus phaeocyanopus is an agaric fungus in the family Pluteaceae. Described as a new species in 2010, it has only been collected from California, where it grows singularly or in groups on the decaying wood of oak. The fruit body has a smooth brown cap measuring 2–4 cm (0.8–1.6 in) in diameter. The stipe is 2–5 cm (0.8–2.0 in) long by 0.4–0.8 cm (0.16–0.31 in) thick, and roughly equal in width throughout. It is whitish but becomes grayish-green near the base. The thin and fragile gills are free from attachment to the stipe, close to somewhat distantly placed, and interspersed with several tiers of lamellulae. The flesh has no distinctive taste or odor. The spores are spherical or nearly so and measure 6.2–8.4 by 5.7–7.9 μm.
Tricholoma vernaticum is an agaric fungus of the genus Tricholoma native to the Pacific Northwest region of the United States. The fungus was originally described in 1976 as a species of Armillaria when that genus was more inclusive; it received its current name twenty years later. The stout fruit bodies (mushrooms) have moist white to grayish caps, a membranous ring on the stipe, and an odor resembling cucumbers. Mycorrhizal with conifers, the fungus fruits in the spring or early summer, with its mushrooms appearing on the ground singly or in groups at high elevations, often at the edge of melting snowbanks. The edibility of the mushroom is unknown, but it has a strong unpleasant odor and a mealy taste.
The Boletineae are a suborder of the fungal order Boletales. Families in the Boletineae include the Boletaceae and the Paxillaceae.
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.
Amanita breckonii is a species of agaric fungus in the genus Amanita. It is known from California and Washington, where it associates with Monterey pine, ponderosa pine, and spruce. The species was described as new to science in 1982 by mycologists Harry Delbert Thiers and Joseph Ammirati. The holotype specimen was collected in 1966 on the campus of San Francisco State University by then graduate student Gary Breckon, for whom the species is named.
Boletus amyloideus is a rare species of bolete fungus in the family Boletaceae. It was described as new to science in 1975 by mycologist Harry D. Thiers, from collections made in California. It fruit bodies have a convex to somewhat flattened reddish-brown cap measuring 3–6 cm (1.2–2.4 in) in diameter. The pore surface on the cap underside is bright yellow, with small angular pores and tubes measuring 4–8 mm long. The spore print is olive-brown; basidiospores are smooth, amyloid, spindle shaped to ellipsoid, and have dimensions of 13–16 by 4.5–5.5 µm. The bolete is known only from coastal California, where it grows on the ground in mixed forests. Its edibility is unknown.
Calonarius verrucisporus is a species of mushroom producing fungus in the family Cortinariaceae.
