Xerocomellus chrysenteron, formerly known as Boletus chrysenteron or Xerocomus chrysenteron and commonly known as the red cracking bolete, is a species of fungus in the family Boletaceae. The small mushroom has tubes and pores instead of gills beneath their caps. It is edible but not choice.

Tapinella atrotomentosa, commonly known as the velvet roll-rim or velvet-footed tap, is a species of fungus in the family Tapinellaceae. Although it has gills, it is a member of the pored mushroom order Boletales. August Batsch described the species in 1783. It has been recorded from Eurasia and North America. Tough and inedible, it grows on tree stumps of conifers. The mushroom contains several compounds that act as deterrents of feeding by insects.

Hemileccinum impolitum is a basidiomycete fungus of the family Boletaceae, native to Europe. It is commonly referred to as the iodine bolete, because its fruit bodies tend to emit an iodine-like odour when cut, more detectable in the stem base or overripe specimens. Like other members of the family, H. impolitum has tubes and pores instead of gills in the hymenial surface of its fruit bodies. It is widely distributed in temperate and southern Europe, where it grows in mycorrhizal symbiosis with broad-leaved trees, particularly oak (Quercus).

Pseudoboletus parasiticus, previously known as Boletus parasiticus and Xerocomus parasiticus, and commonly known as the parasitic bolete, is a rare bolete mushroom found on Scleroderma citrinum earthballs in North America.

Xerocomellus pruinatus, commonly known as the matte bolete and formerly known as Boletus pruinatus or Xerocomus pruinatus, is a mushroom in the family Boletaceae native to Europe. It was transferred to the new genus Xerocomellus described by Czech mycologist Josef Šutara in 2008.

Xerocomellus porosporus is a small wild mushroom in the family Boletaceae. These mushrooms have tubes and pores instead of gills beneath their caps. It is commonly known as the sepia bolete.

Xerocomellus is a genus of fungi in the family Boletaceae. The genus, as it was described in 2008, contained 12 species. However X. rubellus and X. engelii were transferred to the new genus Hortiboletus and X. armeniacus was transferred to the new genus Rheubarbariboletus in 2015. Molecular analysis supports the distinction of Xerocomellus species from Boletus and Xerocomus, within which these species were formerly contained. Xerocomellus in fact is only distantly related to Xerocomus and is most closely related to Tylopilus, Boletus sensu stricto, Porphyrellus, Strobilomyces, and

Pseudoboletus is a genus of fungus in the family Boletaceae. The genus contains two species found in north temperate areas that grow in a parasitic association with species of Scleroderma and Pisolithus, or Astraeus.

Hemileccinum is a genus of fungi in the family Boletaceae. It was erected in 2008 by Josef Šutara to contain two species united by a number of shared morphological features: H. depilatum and the type H. impolitum. In 2014, Wu et al. found it to be distinct from other bolete genera in a molecular phylogenetic study and found it to be most closely related to Corneroboletus. In 2015, H. subglabripes was transferred to Hemileccinum from Boletus based on DNA evidence, while subsequent studies further confirmed the monophyly of the genus.

Butyriboletus roseogriseus is a pored mushroom in the family Boletaceae found in Europe, originally described as a species of Boletus in 2014 before being transferred to the newly created genus Butyriboletus later that same year. The fungus produces large caps 70–120 mm in diameter that start light pink or greyish-pink when young before shifting to grey, ochraceous or brown, with bright yellow tubes and pores that bruise greenish-blue on contact, and a stout yellow stipe featuring a distinctive net-like pattern. It is known only from a few localities in the Maple Mountains of eastern Moravia,

Caloboletus kluzakii is a bolete mushroom native to Europe, primarily found in southern Bohemia in the Czech Republic. First described in 2006, this distinctive fungus was originally classified as Boletus kluzakii before being transferred to the genus Caloboletus in 2014 based on genetic studies. Named in honour of the Czech mycologist Zdeněk Kluzák, who had attempted to describe it earlier, this uncommon mushroom is characterised by its unique colour progression from whitish to rose-pink or purplish-pink as it matures, with a cap surface that quickly turns red when touched. It grows
