Taxonomy

Chinese mycologist Mu Zang, who circumscribed the genus in 1992 with Sinoboletus duplicatoporus as the type species, [1] has been a coauthor on every subsequent described species. The genus name refers to the affiliation with Boletus , and its Chinese distribution. Zang considered the genus to be similar to Boletus or Xerocomus , but suggested that the unique stratified pore arrangement precluded placement in either of these genera. [1]

Description

Sinoboletus species produce caps that range in shape from hemispheric, to convex, to flattened. The cap surface is dry, with a tomentose texture. The flesh of the cap is either thin or thick. The golden yellow to yellow pore surface features crossveins that are arranged in two distinct layers. The pores, initially round, become angular or irregular in age. The club-shaped stipes have a dry surface, with striations at the top but no reticulations. Spores have an ovoid to ellipsoid shape. [1]

Habitat and distribution

Sinoboletus species are suspected to be mycorrhizal with members of the families Fagaceae and Pinaceae, particularly Castanea calathiformis , and Castanea fleuryi . [1]

<span class="mw-page-title-main">Boletaceae</span> Family of fungi

The Boletaceae are a family of mushroom-forming fungi, primarily characterised by small pores on the spore-bearing hymenial surface, instead of gills as are found in most agarics. Nearly as widely distributed as the agarics, the family is renowned for hosting some prime edible species highly sought after by mushroom hunters worldwide, such as the cep or king bolete . A number of rare or threatened species are also present in the family, that have become the focus of increasing conservation concerns. As a whole, the typical members of the family are commonly known as boletes.

<i>Tylopilus felleus</i> Species of fungus

Tylopilus felleus, commonly known as the bitter bolete or the bitter tylopilus, is a fungus of the bolete family. Its distribution includes east Asia, Europe and eastern North America, extending south into Mexico and Central America. A mycorrhizal species, it grows in deciduous and coniferous woodland, often fruiting under beech and oak. Its fruit bodies have convex to flat caps that are some shade of brown, buff or tan and typically measure up to 15 cm (6 in) in diameter. The pore surface is initially white before turning pinkish with age. Like most boletes it lacks a ring and it may be distinguished from Boletus edulis and other similar species by its unusual pink pores and the prominent dark-brown net-like pattern on its stalk.

<i>Phlebopus marginatus</i> Species of fungus

Phlebopus marginatus, commonly known as the salmon gum mushroom in Western Australia, is a member of the Boletales or pored fungi. An imposing sight in forests of south-eastern and south-western Australia, it is possibly Australia's largest terrestrial mushroom, with the weight of one specimen from Victoria recorded at 29 kg (64 lb). Initially described in 1845 as Boletus marginatus, and also previously known by scientific names such as Phaeogyroporus portentosus and Boletus portentosus, it is not as closely related to typical boletes as previously thought.

<i>Suillellus luridus</i> Species of edible fungus of the bolete family, found in Asia, Europe, and eastern North America

Suillellus luridus, commonly known as the lurid bolete, is a fungus of the family Boletaceae, found in calcareous broadleaved woodlands in Europe. Fruit bodies appear in summer and autumn and may be locally abundant. It is a firm bolete with an olive-brown cap up to 20 cm (8 in) in diameter, with small orange or red pores on the underside. The stout ochre stem reaches 8–14 cm (3–6 in) high and 1–3 cm (0.4–1.2 in) wide, and is patterned with a red network. Like several other red-pored boletes, it stains blue when bruised or cut.

<i>Boletellus obscurecoccineus</i> Species of fungus

Boletellus obscurecoccineus, known as the rhubarb bolete, is a species of fungus in the family Boletaceae, found in Australia, New Guinea, Java, Borneo, Japan, Korea, and Taiwan. It is a distinctive and colourful bolete of the forest floor.

<i>Bothia</i> Genus of fungi

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.

<i>Rubroboletus rhodoxanthus</i> Species of fungus

Rubroboletus rhodoxanthus is a species of bolete in the family Boletaceae, native to Europe. Previously known as Boletus rhodoxanthus, it was transferred in 2014 to the newly erected genus Rubroboletus, based on DNA data.

It is a mycorrhizal species and typically grows in association with oak and beech trees.

<i>Boletus abruptibulbus</i> Species of fungus

Boletus abruptibulbus is a species of bolete mushroom in the family Boletaceae. Described as new to science in 2009, it is found only in the Gulf Coast of the Florida Panhandle, where it grows on the ground in coastal sand dunes, one of only three North American boletes known to favor this habitat. The fruit bodies have convex brownish caps up to 8 cm (3.1 in) in diameter, supported by solid yellowish to reddish stems measuring 3–5 cm (1.2–2.0 in) long by 10–15 mm (0.4–0.6 in) thick. The pores on the underside of the cap measure about 1–2 mm in diameter and are initially pale yellow before developing a greenish tinge in age. The mushroom's spores, about 20 micrometers long, are unusually long for a member of the Boletaceae. The stem base is bulbous, a diagnostic feature for which the species is named.

<i>Boletus subvelutipes</i> Species of fungus

Boletus subvelutipes, commonly known as the red-mouth bolete, is a bolete fungus in the family Boletaceae. It is found in Asia and North America, where it fruits on the ground in a mycorrhizal association with both deciduous and coniferous trees. Its fruit bodies (mushrooms) have a brown to reddish-brown cap, bright yellow cap flesh, and a stem covered by furfuraceous to punctate ornamentation and dark red hairs at the base. Its flesh instantly stains blue when cut, but slowly fades to white. The fruit bodies are poisonous, and produce symptoms of gastrointestinal distress if consumed.
