The Boletales are an order of Agaricomycetes containing over 1300 species with a diverse array of fruiting body types. The boletes are the best known members of this group, and until recently, the Boletales were thought to only contain boletes. The Boletales are now known to contain distinct groups of agarics, puffballs, and other fruiting-body types.
Paxillus involutus, also known as the brown roll-rim or the common roll-rim, is a basidiomycete fungus that is widely distributed across the Northern Hemisphere. It has been inadvertently introduced to Australia, New Zealand, South Africa, and South America, probably transported in soil with European trees. Various shades of brown in colour, the fruit body grows up to 6 cm high and has a funnel-shaped cap up to 12 cm wide with a distinctive inrolled rim and decurrent gills that may be pore-like close to the stipe. Although it has gills, it is more closely related to the pored boletes than to typical gilled mushrooms. It was first described by Pierre Bulliard in 1785, and was given its current binomial name by Elias Magnus Fries in 1838. Genetic testing suggests that Paxillus involutus may be a species complex rather than a single species.
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.
Hygrophoropsis aurantiaca, commonly known as the false chanterelle, is a species of fungus in the family Hygrophoropsidaceae. It is found across several continents, growing in woodland and heathland, and sometimes on woodchips used in gardening and landscaping. Fruit bodies (mushrooms) are yellow–orange, with a funnel-shaped cap up to 8 cm across that has a felt-like surface. The thin, often forked gills on the underside of the cap run partway down the length of the otherwise smooth stipe. Reports on the mushroom's edibility vary – it is considered poisonous, but has historically been eaten in parts of Europe and the Americas.
The Paxillaceae are a family of mushroom-forming fungi bearing close affinity to the boletes. Collectively, the family contains nine genera and 78 species. The type genus is Paxillus, containing fungi with decurrent gills, and Gyrodon, which has members with decurrent pores, among others. French mycologist René Maire had erected the family in 1902, placing it between the agarics and boletes and recognizing the groups' similarities with the latter group. Maire's usage of the name was later deemed to be invalid, and the genus authority is attributed to Johannes Paulus Lotsy. Molecular research confirms the relations of Gyrodon, with the decurrent-pored mushroom G. lividus, Paragyrodon, with the type species P. sphaerosporus, and Paxillus as sister groups, together lying near the base of a phylogenetic tree from which the genus Boletus arises. The name Gyrodontaceae, published by Belgian botanist Paul Heinemann in 1951, is considered synonymous with Paxillaceae.
The Sclerodermataceae are a family of fungi in the order Boletales, containing several genera of unusual fungi that little resemble boletes. Taxa, which include species commonly known as the ‘hard-skinned puffballs’, ‘earthballs’, or 'earthstars', are widespread in both temperate and tropical regions. The best known members include the earthball Scleroderma citrinum, the dye fungus Pisolithus tinctorius and the 'prettymouths' of the genus Calostoma.
Gyrodon lividus, commonly known as the alder bolete, is a pored mushroom bearing close affinity to the genus Paxillus. Although found predominantly in Europe, where it grows in a mycorrhizal association with alder, it has also recorded from China, Japan and California. Fruit bodies are distinguished from other boletes by decurrent bright yellow pores that turn blue-grey on bruising. G. lividus mushrooms are edible.
Gyrodon is a genus of pored mushroom bearing close affinity to the genus Paxillus. Recent molecular research has confirmed this relationship of the two genera as sister taxa, together diverging as one of the most basal lineages in the Boletineae, and sister to the Boletaceae.
Calostoma is a genus of 29 species of gasteroid fungi in the suborder Sclerodermatineae. Like other gasteroid fungi, Calostoma do not have the spore discharge mechanism associated with typical gilled fungi (ballistospory), and instead have enclosed spore-bearing structures. Resembling round puffballs with raised, brightly colored spore openings (ostioles), elevated on a thick, gelatinous stalks, species have been collected in regions of deciduous, temperate, tropical or subtropical forests. Their distribution includes eastern North America, Central America, Asia, and Australasia. The common name given to some species, "prettymouth", alludes to the brightly colored raised openings (ostioles) that may somewhat resemble lips. Other common names include "hotlips" and "puffball in aspic".
Phlebopus is a genus of fungi in the family Boletinellaceae. The genus has a widespread distribution in subtropical and pantropical regions, and contains 12 species. The species are saprobic, with some possibly able to form mycorrhizae with exotic trees in certain conditions. It contains the gigantic Phlebopus marginatus, the cap of which can reach 1 m (3.3 ft) in diameter.
Aureoboletus mirabilis, commonly known as the admirable bolete, the bragger's bolete, and the velvet top, is an edible species of fungus in the Boletaceae mushroom family. The fruit body has several characteristics with which it may be identified: a dark reddish-brown cap; yellow to greenish-yellow pores on the undersurface of the cap; and a reddish-brown stem with long narrow reticulations. Aureoboletus mirabilis is found in coniferous forests along the Pacific Coast of North America, and in Asia. Unusual for boletes, A. mirabilis sometimes appears to fruit on the wood or woody debris of Hemlock, suggesting a saprobic lifestyle. Despite occasional appearances to the contrary, Aureoboletus mirabilis is mycorrhizal, and forms close mutualistic associations with hemlock roots.
Suillus brevipes is a species of fungus in the family Suillaceae. First described by American mycologists in the late 19th century, it is commonly known as the stubby-stalk or the short-stemmed slippery Jack. The fruit bodies (mushrooms) produced by the fungus are characterized by a chocolate to reddish-brown cap covered with a sticky layer of slime, and a short whitish stipe that has neither a partial veil nor prominent, colored glandular dots. The cap can reach a diameter of about 10 cm, while the stipe is up to 6 cm long and 2 cm thick. Like other bolete mushrooms, S. brevipes produces spores in a vertically arranged layer of spongy tubes with openings that form a layer of small yellowish pores on the underside of the cap.
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.
Calostoma cinnabarinum, commonly known as the stalked puffball-in-aspic,gelatinous stalked-puffball, or red slimy-stalked puffball, is a species of gasteroid fungus in the family Sclerodermataceae, and is the type species of the genus Calostoma. The fruit body has a distinctive color and overall appearance, featuring a layer of yellowish jelly surrounding a bright red, spherical head approximately 2 centimeters (0.8 in) in diameter atop a red or yellowish brown spongy stipe 1.5 to 4 cm tall. The innermost layer of the head is the gleba, containing clear or slightly yellowish elliptical spores, measuring 14–20 micrometers (µm) long by 6–9 µm across. The spore surface features a pattern of small pits, producing a net-like appearance. A widely distributed species, it grows naturally in eastern North America, Central America, northeastern South America, and East Asia. C. cinnabarinum grows on the ground in deciduous forests, where it forms mycorrhizal associations with oaks.
Sclerodermatineae is a suborder of the fungal order Boletales. Circumscribed in 2002 by mycologists Manfred Binder and Andreas Bresinsky, it contains nine genera and about 80 species. The suborder contains a diverse assemblage fruit body morphologies, including boletes, gasteroid forms, earthstars, and puffballs. Most species are ectomycorrhizal, although the ecological role of some species is not known with certainty. The suborder is thought to have originated in the late Cretaceous (145–66 Ma) in Asia and North America, and the major genera diversified around the mid Cenozoic (66–0 Ma).
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.
Strobilomyces glabriceps is a species of bolete fungus in the family Suillaceae found in China. It was described as new to science in 1948 by Wei-Fan Chiu. The type collection was made in Kunming in June, 1938.
Aureoboletus betula is a species of mushroom producing fungus in the family Boletaceae. It is commonly known as the Shaggy Stalked Bolete.
Hypsizygus ulmarius, also known as the elm oyster mushroom, and less commonly as the elm leech, elm Pleurotus, is an edible fungus. It has often been confused with oyster mushrooms in the Pleurotus genus but can be differentiated easily as the gills are either not decurrent or not deeply decurrent. While not quite as common as true oyster mushrooms, they have a wide range globally in temperate forests. The mushrooms and vegetative hyphae of this species have been studied in recent years for their potential benefits to human health, and mycoremediation.
Pulveroboletus sinensis is a species of blue staining bolete fungus of the family Boletaceae and the genus Pulveroboletus found in the Guangdong Province in China. It is characterized by its yellow to vivid-yellow pulverulent cap which can darken to a deep orange at the center, and is covered with deep-orange to brown-orange conico-pyramidal scales. The cap is cyanescent when cut or bruised, while the stem does not stain. These scales distinguish P. sinensis from a closely related species Pulveroboletus brunneopunctatus.
