Leccinellum griseum is a common, edible mushroom in the bolete family. It is found below hornbeam, usually in small groups. Young mushrooms with firm flesh are very palatable.

The Suillaceae are a family of fungi in the order Boletales (suborder Suillineae), containing the boletus-like Suillus, the small truffle-like Truncocolumella, as well as the monotypic genus Psiloboletinus. As of 2008, there are 54 species in the family. Gastrosuillus, once considered a distinct genus, has been shown with molecular analysis to be a recent evolutionary derivative of Suillus. Fuscoboletinus, described by Pomerleau and Smith in 1962, has also been subsumed into Suillus.

The Omphalotaceae are a family of fungi in the order Agaricales. Basidiocarps (fruit bodies) are most frequently agarics (gilled mushrooms), but occasionally corticioid (in the genus Brunneocorticium) or poroid (in the genus Hymenoporus).

Leccinellum lepidum is a species of bolete in the family Boletaceae. Originally described as Boletus lepidus in 1965, the fungus has gone through controversial taxonomic treatments over the years and was subsequently transferred to genus Krombholziella in 1985, to genus Leccinum in 1990, and to genus Leccinellum in 2003. It is the sister-species of Leccinellum corsicum, with which it had been erroneously synonymised by some authors in the past. Like other species of Boletaceae, it has tubes and pores instead of gills in its hymenial (fertile) surface and produces large, fleshy fruit bodies up

Leccinellum is a genus of fungi in the family Boletaceae. Mycologists Andreas Bresinsky and Manfred Binder circumscribed the genus in 2003 to contain Leccinum species with a yellow pore surface and a trichoderm-like cap cuticle. Leccinellum nigrescens (originally Leccinum nigrescens Singer 1947) was designated the type species; this taxon has since been renamed to Leccinellum crocipodium (Letell.) Della Maggiora & Trassinelli. The oak-associating Leccinellum quercophilum was described from the United States in 2013.

The Serpulaceae are a family of fungi in the Boletales order. According to the Dictionary of the Fungi (10th edition, 2008), the family contains 4 genera and 20 species. However, a molecular phylogenetics study showed that the genus Neopaxillus, which was formerly placed in this family, belongs in the family Crepidotaceae in the order Agaricales.

Omphalotus illudens, commonly known as the eastern jack-o'lantern mushroom, is a North American species of fungus.

Leratiomyces is a genus of mushroom-forming basidiomycetes first proposed three times under invalid names, and finally validated in 2008. It includes several formerly described, variously, from the genera Stropharia, Hypholoma, and Weraroa. It was formerly classified as Stropharia section Stropholoma, though some authorities placed this section in the genus Hypholoma, as these species often have features that are intermediate between the two genera. The genus name of Leratiomyces is in honour of Auguste Le Rat (1872-1910), who was a French teacher, and in 1904 was the curator of the Museums

Leccinellum corsicum is a species of bolete fungus in the family Boletaceae. It grows in mycorrhizal symbiosis exclusively with rockroses (Cistus species) in Mediterranean Europe and North Africa. The fungus was originally described as new to science in 1896 by French mycologist Léon Louis Rolland as a species of Boletus. Andreas Bresinsky and Manfred Binder transferred it to the newly circumscribed genus Leccinellum in 2003. The bolete is edible, and is especially appreciated in Portugal.

The Gyroporaceae are a family of fungi in the order Boletales. The family is monogeneric, containing the single genus Gyroporus, which, according to a 2008 estimate, contains ten widely distributed species, though a more recent study suggested the species-level diversity to be far higher. As of January 2026, according to Index Fungorum and Mycobank databases, the genus had 46 species.

Retiboletus ornatipes, commonly known as the ornate-stalked bolete or goldstalk, is a species of bolete fungus in the family Boletaceae. Originally named Boletus ornatipes by American mycologist Charles Horton Peck in 1878, it was transferred to Retiboletus in 2002. The convex cap is 4–20 centimetres (1+1⁄2–8 in) wide and yellow, gray, or brown, staining orangish. The stem is 6–12 cm (2+1⁄4–4+3⁄4 in) tall and 1–2.5 cm (1⁄2–1 in) thick. The flesh is yellow with a mild to bitter taste. The spore print is tannish brown. It can be found under oak and beech in eastern North America from July to

Retiboletus is a genus of fungi in the family Boletaceae. The genus, first described in 2002, contained six species distributed in north temperate regions.

Leccinellum albellum is a species of bolete fungus in the family Boletaceae.

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 (genus Astraeus), 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

Retiboletus griseus, commonly known as the gray bolete, is a species of bolete fungus in the family Boletaceae.

Porpolomopsis calyptriformis, commonly known as the pink wax cap, ballerina waxcap or salmon waxy cap, is a species of agaric (gilled mushroom) in the family Hygrophoraceae. The species has a European distribution, occurring mainly in agriculturally unimproved grassland. Threats to its habitat have resulted in the species being assessed as globally "vulnerable" on the IUCN Red List of Threatened Species. A similar but as yet unnamed species occurs in North America.

Austropaxillus infundibuliformis (formerly Paxillus infundibuliformis) is a species of fungus in the family Serpulaceae. A mycorrhizal species, it grows in the eucalypt forests of southeastern Australia. It is readily recognised by its tawny yellow colour, large size (relative to other Australian mushrooms) and forked decurrent gills.

Porpolomopsis is a genus of fungi in the family Hygrophoraceae. It was circumscribed in 2008 by Andreas Bresinsky to contain P. calyptriformis. Bresinsky separated it from the genus Hygrocybe based on its color and the absence of DOPA pigments. P. lewelliniae was transferred to the genus based on DNA and morphology. Three undescribed species also belong in the genus. Species of Porpolomopsis have also formerly been placed in the genus Humidicutis, to which they are closely related but differ in having narrowly attached or free gills and the shape of the hyphae in their cap. Species of
