Suillus lakei, commonly known as the matte Jack, Lake's bolete, or the western painted Suillus, is a species of fungus in the family Suillaceae. It is characterized by the distinctive reddish-brown tufted fibers or small scales on the cap, and the presence of a woolly veil on the stem. The caps can reach diameters of up to 15 cm, while the stems are between 6 and 12 cm long and usually 1–3 cm thick. On the underside of the cap is a layer of spongy yellow to yellow-brown angular pores; these pores are covered with a whitish partial veil when young. A mycorrhizal fungus, S. lakei grows in association with Douglas fir, and is found where this tree occurs. It is native to northwestern North America, but has been introduced to Europe, South America, and New Zealand. The mushroom is edible, but opinions vary considerably as to its quality.
Skeletocutis is a genus of about 40 species of poroid fungi in the family Polyporaceae. The genus has a cosmopolitan distribution, although most species are found in the Northern Hemisphere. It causes a white rot in a diverse array of woody substrates, and the fruit bodies grow as a crust on the surface of the decaying wood. Sometimes the edges of the crust are turned outward to form rudimentary bracket-like caps.
Amanita nothofagi is a species of fungus in the family Amanitaceae. Endemic to New Zealand, the species was first described by mycologist Greta Stevenson in 1962. The fruit bodies have dark brown caps that are up to 13 cm (5.1 in) in diameter and covered with patches of soft greyish-brown scales or warts. The gills underneath the cap are crowded together, free from attachment to the stem, and white, becoming tinged with yellow in age. The stem of the mushroom is 4–14 cm (1.6–5.5 in) long by 0.5–2.5 cm (0.2–1.0 in) thick, and has a ring. The spore print is white, and individual spores are spherical to ellipsoid, measuring 7.5–9 by 7.5–9 micrometres. The mushroom may be confused with another New Zealand species, A. australis, but can be distinguished by certain characteristics. Amanita nothofagi is a mycorrhizal species, and grows in association with native New Zealand trees such as Southern Beech.
Butyriboletus regius, commonly known as the royal bolete or red-capped butter bolete, is a basidiomycete fungus of the genus Boletus found in China and Europe. B. regius has a pink cap, yellow flesh, and a reticulate pattern on the stem. Harry D. Thiers described a similar mushroom from California as B. regius, though it is not the same species. B. regius in Europe does not stain when exposed to air, or stains weakly, but the California species stains blue. Both European and California species are considered choice edibles.
Boletus rubroflammeus is a species of bolete fungus in the family Boletaceae. First described from Michigan in 1971, it is found in the eastern United States and Mexico, where it grows in a mycorrhizal association with hardwood trees. The fruit bodies (mushrooms) of the fungus have caps that are deep red to purplish red, and dark red pores. The stem has coarse, dark red reticulations and a narrow yellow area at the top. All parts of the mushroom quickly stain blue when injured or cut. Lookalikes include Boletus flammans, a lighter-colored species that grows with conifers. Other similar species can be distinguished by differences in distribution, morphology, staining reaction, and microscopic characteristics. Boletus rubroflammeus mushrooms are poisonous, and can cause gastrointestinal distress if consumed.
Boletus carminiporus is a species of bolete fungus in the family Boletaceae. Described as new to science in 1998, the species is found in the southern United States where it grows in a mycorrhizal association with various trees in mixed forests.
Boletopsis nothofagi is a fungus in the family Bankeraceae. The fungus forms grey fruit bodies that grow in clusters. Like all species of Boletopsis, it has a porous spore-bearing surface on the underside of the cap, but differs from other species of Boletopsis by having characteristics such as elongated spores and a green discoloration when stained with potassium hydroxide. Boletopsis nothofagi is endemic to New Zealand and has a mycorrhizal association with red beech. It is unknown when exactly the fungus forms its fruit body, but it has so far been found solely in May, during autumn in the Southern Hemisphere.
Lepiota castaneidisca is a species of agaric fungus in the family Agaricaceae. Formally described in 1912, it was for a long time considered the same species as the similar Lepiota cristata until molecular analysis reported in 2001 demonstrated that it was genetically distinct. It is most common in coastal and northern California, and has also been recorded in Mexico. A saprobic species, it is usually found under redwood and Monterey cypress. Its fruit bodies (mushrooms) have white caps with an orange-red to orange-brown center that measure up to 3.2 cm (1.3 in) wide. The cream-colored to light pink stems are up to 6.5 cm (2.6 in) long by 0.2–0.6 cm (0.1–0.2 in) thick, and have a ring. L. castaneidisca can be distinguished from other similar Lepiota species by differences in habitat, macroscopic, or microscopic characteristics.
Imperator torosus, commonly known as the brawny bolete, is a species of bolete fungus in the family Boletaceae. It is native to southern Europe east to the Caucasus and Israel. It is generally associated with deciduous trees such as hornbeam, oak and beech in warm, dry locales. Although generally rare in Europe, it appears to be relatively common in Hungary. Appearing in summer and autumn on chalky soils, the stocky fruit bodies have an ochre cap up to 20 cm (8 in) across, yellow pores on the cap underside, and a wine-red to brown or blackish stipe up to 6–15 cm (2.4–5.9 in) long by 3–6 cm (1.2–2.4 in) wide. The pale yellow flesh changes to different colours when broken or bruised depending on age; younger mushrooms become reddish, and older ones additionally take on bluish tones.
Boletus subluridellus is a species of bolete fungus in the family Boletaceae. Described as new to science in 1971 by American mycologists, the bolete is found in the eastern United States and Canada. It grows on the ground in coniferous and mixed forests in a mycorrhizal association with deciduous trees, especially oak. The fruit bodies (mushrooms) have orangish-red, broadly convex caps that are up to 10 cm (3.9 in) in diameter, with small, dark reddish pores on the underside. The pale yellow stipe measures 4–9 cm (1.6–3.5 in) long by 1.5–2.3 cm (0.6–0.9 in) thick. All parts of the fruit body will quickly stain blue when injured or touched.
Skeletocutis africana is a species of poroid crust fungus in the family Polyporaceae.

Nigroporus vinosus is a species of poroid fungus in the family Steccherinaceae, and the type species of the genus Nigroporus. Its fruit bodies have brownish caps with tinges of purple or red. The cap underside has a pore surface the same colour as the cap, and minute pores. Nigroporus vinosus has a pantropical distribution. It has been recorded from Africa, North America, Central America, South America, Asia, and Oceania. It is a wood-decay fungus that causes a white rot.
Skeletocutis diluta is a species of poroid crust fungus in the family Polyporaceae. It was first described by Mario Rajchenberg in 1983 as a variety of Skeletocutis nivea. Rajchenberg and Alex David promoted the taxon to independent species status in 1992. The type specimen was collected in Puerto Esperanza, Misiones (Argentina), where it was found growing on Pinus taeda logs in a subtropical forest. It has since been found in Gabon. Skeletocutis diluta has effused-reflexed fruit bodies, meaning they are crust-like with a margin that is extended and bent backwards. It has small allantoid (sausage-shaped) spores measuring 3.1–3.5 by 0.5–0.8 μm. It features a dimitic hyphal system, but the skeletal hyphae dissolve in solution of potassium hydroxide.
Skeletocutis yunnanensis is a species of poroid crust fungus in the family Polyporaceae that was described as a new species in 2016. The type specimen was collected in northern Yunnan Province, southwestern China, where it was found growing on decaying angiosperm wood in a temperate forest.
Skeletocutis subvulgaris is a species of poroid, white rot fungus in the family Polyporaceae. Found in China, it was described as a new species in 1998 by mycologist Yu-Chen Dai. It was named for its resemblance to Skeletocutis vulgaris. The type collection was made in Hongqi District, Jilin Province, where it was found growing on the rotting wood of Korean pine.
Skeletocutis stramentica is a species of poroid fungus in the family Polyporaceae that is found in New Zealand.
