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.
Neoboletus luridiformis, also previously known as Boletus luridiformis and (invalidly) as Boletus erythropus, is a fungus of the bolete family, all of which produce mushrooms with tubes and pores beneath their caps. It is found in Northern Europe and North America, and is commonly known as the scarletina bolete, for its red pores, which are yellow when young. Other common names include the red foot bolete, dotted stemmed bolete, or dotted stem bolete.
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.
Aureoboletus is a genus of bolete fungi in the family Boletaceae. It was circumscribed by Czech mycologist Zdeněk Pouzar in 1957. A taxonomic monograph was published in 2010 by Wolfgang Klofac.
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.
Suillellus queletii, commonly known as the deceiving bolete, is an uncommon, edible mushroom in the genus Suillellus.
Exsudoporus floridanus is a species of edible bolete mushroom in the family Boletaceae. In 1945, American mycologist Rolf Singer described a species he found in Florida during his 1942–3 tenure of a Guggenheim Memorial Fellowship. He originally described it as a subspecies of the eastern North American species Boletus frostii, but later considered it worthy of distinct species status in a 1947 publication. Based on morphological and phylogenetic data, Vizzini and colleagues transferred this species to a newly described genus Exsudoporus in 2014. Due to lack of sufficient sequences, Wu et al. (2016) were reluctant to accept Exsudoporus and considered it a synonym of Butyriboletus, so they proposed a new combination Butyriboletus floridanus. However, following phylogenetic and morphological analyses clearly resolved Exsudoporus as a monophyletic, homogenous and independent genus that is sister to Butyriboletus.
Sutorius is a genus of fungi in the family Boletaceae. Its type species is the widely distributed Sutorius eximius. The Asian Boletus obscureumbrinus, found in Japan and China, was described by Japanese mycologist Tsuguo Hongo in 1968, moved to genus Sutorius in 2016, but then reclassified into genus Neoboletus in 2019. The Australian Sutorius australiensis and the southern Chinese Sutorius subrufus also belong to the genus.
Neoboletus pseudosulphureus is a species of bolete fungus in the family Boletaceae. It is found in Europe, Central America, North America, and India, where it grows in deciduous and mixed forests. Initially uniformly yellow in color, all external surfaces of the fruit body undergo a variety of discolorations as it matures.
Butyriboletus is a genus of fungi in the family Boletaceae. The genus was circumscribed in 2014 by mycologists David Arora and Jonathan L. Frank to accommodate "butter bolete" species that were shown by molecular analysis to be phylogenetically distinct from Boletus. Butyriboletus contains 24 ectomycorrhizal species found in Asia, Europe, North America and north Africa.
Butyriboletus fuscoroseus is a pored mushroom in the family Boletaceae. It was formerly considered a species of Boletus, but in 2014 was transferred to the newly created genus Butyriboletus. Boletus pseudoregius, a European taxon originally described as a subspecies of Boletus appendiculatus in 1927, is a synonym. B. fuscoroseus is considered critically endangered in the Czech Republic.
Suillellus hypocarycinus is a species of bolete fungus found in North America. Originally described as a species of Boletus by Rolf Singer in 1945, it was transferred to Suillellus by William Alphonso Murrill in 1948.
Suillus kunmingensis is a species of bolete fungus in the family Suillaceae. It was described as new to science in 1948 by Wei-Fan Chiu as a species of Boletinus; Wang and Yao transferred it to the genus Suillus in a 2004 nomenclatural revision of several Chinese boletes. The species epithet alludes to the type locality—Kunming, China—where the first scientific collections of the bolete were made in November, 1941. It has also been recorded from Sichuan. Similar Suillus species include S. pinetorum and S. punctatipes.
Rubroboletus is a genus of bolete fungi in the family Boletaceae. It was circumscribed by Chinese mycologists in 2014 with Rubroboletus sinicus as the type species. Species are characterized by having a reddish cap surface, yellow tubes on the underside of the cap, and an orange-red to blood-red pore surface. Pinkish to red spots (reticula) are present on the stipe surface, and a bluish color change occurs when the bolete flesh is injured. Rubroboletus mushrooms have an olive-brown spore print, and produce smooth spores. Eight species were included in the original circumscription ; five were added in 2015, and another in 2017.
Rubroboletus haematinus is a fungus of the genus Rubroboletus. First described scientifically in 1976 by Roy Halling as a species of Boletus, in 2015 it was transferred to Rubroboletus, a genus circumscribed the year previously to contain other allied reddish colored, blue-staining bolete species. It is found in the western United States.
Neoboletus venenatus, known until 2015 as Boletus venenatus, is a species of bolete fungus in the family Boletaceae native to Japan and China. It was transferred to the new genus Neoboletus by Chinese mycologists Gang Wu and Zhu L. Yang in 2015.
Caloboletus is a fungal genus in the family Boletaceae. It was circumscribed by Italian mycologist Alfredo Vizzini with Caloboletus calopus as the type species. The erection of Caloboletus follows recent molecular studies that outlined a new phylogenetic framework for the Boletaceae. Boletus peckii was also transferred to this genus by Vizzini, but was subsequently moved to the genus Butyriboletus based on molecular evidence. The generic name Caloboletus, derived from the Greek calos "nice", refers to the attractive red coloring of the stipe.
Caloboletus frustosus is a bolete fungus native to North America. Until 2014, it was known as Boletus frustosus. Recent changes in the phylogenetic framework of the family Boletaceae prompted the transfer of this species, along with several other related boletes, including Caloboletus calopus, to the genus Caloboletus. It was first described scientifically in 1941 by mycologists Wally Snell and Esther Dick.
Sutorius eximius, commonly known as the lilac-brown bolete, is a species of fungus in the family Boletaceae. This bolete produces fruit bodies that are dark purple to chocolate brown in color with a smooth cap, a finely scaly stipe, and a reddish-brown spore print. The tiny pores on the cap underside are chocolate to violet brown. It is widely distributed, having been recorded on North America, South America, and Asia, where it grows in a mycorrhizal relationship with both coniferous and deciduous trees.
Sutorius magnificus, known until 2014 as Boletus magnificus, is a species of bolete fungus in the family Boletaceae native to Yunnan province in China. It was transferred to the new genus Neoboletus in 2014, and then Sutorius in 2016.
