Pulveroboletus is a genus of fungi in the family Boletaceae. The genus has a cosmopolitan distribution and contains 41 species. [1]
The genus was first described by American mycologist William Alphonso Murrill in 1909. He defined species in the genus as having a cap and stem "clothed with a conspicuous sulphur-yellow, powdery tomentum, which may be the remains of a universal veil: context white, fleshy; tubes adnate, yellowish, covered with a large veil: spores oblong-ellipsoid, ochraceous-brown: stipe solid, annulate, not reticulate." Murrill set Pulveroboletus ravenelii as the type species . [2]
The genus consists of the following species: [1]
Index Fungorum is an international project to index all formal names in the fungus kingdom. As of 2015 the project is based at the Royal Botanic Gardens, Kew, one of three partners along with Landcare Research and the Institute of Microbiology, Chinese Academy of Sciences.
Buchwaldoboletus is a genus of bolete fungi in the family Boletaceae. It was circumscribed by mycologist Albert Pilát in 1969. According to a 2011 survey of the genus, Buchwaldoboletus contains about a dozen species that are saprotrophic and lignicolous.
Asteridiella is a genus of fungi in the family Meliolaceae. The genus was first described by Daniel McAlpine in 1897, who differentiated it from various other fungal genera:
"Asterula, Sacc, has continuous hyaline spores (Hyalosporae), Asteronia, Sacc, has continuous brown spores (Phaeosporae). Asterina, Lev., has two-celled hyaline spores (Hyalodidymae). Asterella, Sacc, has two-celled brown spores (Phaeodidymae). Asteridium, Sacc, has multi-septate hyaline spores (Hyalophragmiae). And in the case of the specimen on Solanum viride with multi-septate brown spores, I have ventured to use Asteridiella (Phaeophragmiae)".
Bothia is a fungal genus in the family Boletaceae. A monotypic genus, it contains the single species Bothia castanella, a bolete mushroom first described scientifically in 1900 from collections made in New Jersey. Found in the eastern United States, Costa Rica, China, and Taiwan, it grows in a mycorrhizal association with oak trees. Its fruit body is chestnut brown, the cap is smooth and dry, and the underside of the cap has radially elongated tubes. The spore deposit is yellow-brown. The edibility of the mushroom is unknown. Historically, its unique combination of morphological features resulted in the transfer of B. castanella to six different Boletaceae genera. Molecular phylogenetic analysis, published in 2007, demonstrated that the species was genetically unique enough to warrant placement in its own genus.
Flaviporus is a genus of poroid fungi in the family Steccherinaceae.
Carlo Luigi Spegazzini, in Spanish Carlos Luis Spegazzini, was an Italian-born Argentinian botanist and mycologist.
Mackintoshia is a fungal genus in the family Boletaceae. It was originally placed in Cortinariaceae. The genus is monotypic, containing the single truffle-like species Mackintoshia persica, found in Zimbabwe. This fungus, eaten by both the common duiker and the Karanga people, is little known outside the Midlands Province of Zimbabwe. Mackintoshia was circumscribed by Giovanni Pacioni and Cathy Sharp in 2000. The genus name honors British-Rhodesian farmer Robbie Mackintosh, who collected and documented some early specimens. The specific epithet persica is Latin for peach, referring to its odor.
Boletus curtisii is a species of fungus in the family Boletaceae. It produces small- to medium-sized fruit bodies (mushrooms) with a convex cap up to 9.5 cm (3.7 in) wide atop a slender stem that can reach a length of 12 cm (4.7 in). In young specimens, the cap and stem are bright golden yellow, although the color dulls to brownish when old. Both the stem and cap are slimy or sticky when young. On the underside of the cap are small circular to angular pores. The mushroom is edible, but not appealing. It is found in eastern and southern North America, where it grows in a mycorrhizal association with hardwood and conifer trees. Once classified as a species of Pulveroboletus, the yellow color of B. curtisii is a result of pigments chemically distinct from those responsible for the yellow coloring of Pulveroboletus.
Boletinellus merulioides, commonly known as the ash-tree bolete, is a species of bolete fungus in the family Boletinellaceae. Described as new to science in 1832, it is found in Asia and eastern North America, where it grows on the ground near ash trees.
Pulveroboletus ravenelii, commonly known as Ravenel's bolete or the powdery sulfur bolete, is a species of bolete fungus in the family Boletaceae. Described as new to science in 1853, the widely distributed species is known from Asia, Australia, North America, Central America, and South America. Mycorrhizal with oak, the fungus fruits on the ground singly, scattered, or in groups in woods. Fruit bodies (mushrooms) have convex to flat, yellowish to brownish-red caps up to 10 cm (4 in) in diameter. On the cap underside, the pore surface is bright yellow before turning dingy yellow to grayish brown with age; it stains greenish blue then grayish brown after injury. A cottony and powdery partial veil remains as a ring on the stipe. The mushrooms are edible, and have been used in traditional Chinese medicine and for mushroom dyeing.
Buchwaldoboletus lignicola is a species of bolete fungus in the family Boletaceae native to Europe and North America. Found on wood, it is actually parasitic on the fungus Phaeolus schweinitzii. It has a convex yellow- to rusty brown cap, yellow to yellow-brown pores and stipe, and a brown spore print. Its edibility is unknown.
Butyriboletus peckii is a fungus of the genus Butyriboletus native to eastern North America. It was first described by Charles Christopher Frost in 1878. Until 2014, it was known as Boletus peckii. Recent changes in the phylogenetic framework of the Boletaceae prompted the transfer of this species, along with several other related boletes, including Caloboletus calopus, to the genus Caloboletus. In 2015, Kuan Zhao and colleagues published analysis that demonstrated that the bolete belongs to Butyriboletus, closely related to Butyriboletus pulchriceps.
Peziotrichum is a genus of ascomycete fungus. It is an entomogenous fungus, meaning that it is found growing on the body of insects.
Cystoagaricus strobilomyces is a species of mushroom producing fungus in the family Psathyrellaceae and the type species of the Cystoagaricus genus
Hygronarius is a genus of fungi in the family Cortinariaceae.
Buchwaldoboletus acaulis is a species of bolete fungus in the family Boletaceae native to Lesser Antilles and Martinique. Found on wood in xero-mesophytic forests, it has a convex bright yellow cap, sulfur-yellow pores and stipe, and a brown spore print. Its edibility is unknown.
Buchwaldoboletus xylophilus is a species of bolete fungus in the family Boletaceae native to Asia, found on wood. It has a convex brown cap, and a red-brown stipe. Its edibility is unknown.
Buchwaldoboletus duckeanus is a species of bolete fungus in the family Boletaceae native to South America.
Buchwaldoboletus brachyspermus is a species of bolete fungus in the family Boletaceae native to Martinique.
Buchwaldoboletus parvulus is a species of bolete fungus in the family Boletaceae native to India. It grows on dead bamboo stumps, has a convex bright yellow cap, yellow to red-brown pores, and a yellow above, reddish below stipe.
