Bisporella citrina, commonly known as yellow fairy cups or lemon discos, is a species of fungus in the family Helotiaceae. The fungus produces tiny yellow cups up to 3 mm in diameter, often without stalks, that fruit in groups or dense clusters on decaying deciduous wood that has lost its bark. The widely distributed species is found in North Africa, Asia, Europe, North America, and Central and South America. Found in late summer and autumn, the fungus is fairly common, but is easily overlooked owing to its small size. There are several similar species that can in most cases be distinguished by differences in color, morphology, or substrate. Microscopically, B. citrina can be distinguished from these lookalikes by its elliptical spores, which have a central partition, and an oil drop at each end.
Cericium is a fungal genus in the family Cystostereaceae. It is a monotypic genus with the single species Cericium luteoincrustatum, a crust fungus. This species was originally described in 1986 by Kurt Hjortstam and Leif Ryvarden, who called it Amethicium luteoincrustatum. They placed it in the genus Amethicium based on microscopic similarities with the African species Amethicium rimosum.
Pulveroboletus bembae is a species of fungus in the family Boletaceae that was first described in 2009. It is known only from the rainforest of northern Gabon, a region known for its high level of species diversity. Like all boletes, P. bembae has fleshy fruit bodies that form spores in tubes perpendicular to the ground on the underside of the cap. These yellowish tubes form a surface of pores, each about 1–2 mm in diameter. The brownish caps may reach up to 3.5 cm (1.4 in) wide, and rest atop pale brown stems up to 5.5 cm (2.2 in) long. The stems have a woolly, whitish yellow ring of tissue that is short-lived, and may be absent in older specimens. The spores of P. bembae are spindle- or fuse-shaped, and have rough surfaces—a detail observable when viewed with scanning electron microscopy. The fungus grows in a mycorrhizal relationship with Gilbertiodendron dewevrei, the dominant tree species of the Guineo-Congolian rainforest. Other similar Pulveroboletus species in the area include P. annulus and P. croceus, which may be differentiated from P. bembae by a combination of macro- and microscopic characteristics.
Amanita ravenelii, commonly known as the pinecone lepidella, is a species of fungus in the family Amanitaceae. The whitish fruit bodies are medium to large, with caps up to 17 centimetres wide, and stems up to 25 cm (10 in) long. The cap surface has large warts and the stem has a scaly, bulbous base. The mushrooms have a unique chlorine like odor.
Lepiota harithaka is an agaric mushroom of the genus Lepiota in the order Agaricales. It was described as new to science in 2009. Found in Kerala State, India, fruit bodies of the fungus grow on the ground among bamboo roots.
Cortinarius sinapivelus is a species of truffle-like fungus in the family Cortinariaceae. Known only from New South Wales, it was described as new to science in 2010.
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. Described as new to science in 2006 by mycologists Leif Ryvarden and Peter Roberts, the fungus is found in Cameroon, where it grows on logs in tropical lowland rainforest environments. The type collection was made in Korup National Park, in South West Province.
Skeletocutis bicolor is a species of poroid crust fungus in the family Polyporaceae. It is found in Singapore.
Skeletocutis borealis is a rare species of poroid fungus in the family Polyporaceae. Found in northern Europe, it was described as new to science in 1998 by Finnish mycologist Tuomo Niemelä.

Fibroporia bohemica is a species of poroid crust fungus in the family Fomitopsidaceae.
Crustomyces subabruptus is a species of toothed crust fungus in the family Cystostereaceae.
Dichomitus eucalypti is a crust fungus that was described as a new species in 1985 by Norwegian mycologist Leif Ryvarden. The fruit body of the fungus measures 1–2 cm in diameter, and has a white to pale cream pore surface with small round pores numbering 2–3 per millimetre. D. eucalypti has a dimitic hyphal structure, containing both generative and binding hyphae. Generative hyphae are thin walled with clamps, and measure 2.5–4 μm in diameter. Found in the context, the binding hyphae are solid, hyaline, and measure 2–5 μm. Spores are more or less cylindrical, thin-walled and hyaline, and have dimensions of 7–8.5 by 3–4 μm.

Mycorrhaphium africanum is a species of tooth fungus in the family Steccherinaceae. It was described as new to science in 2003 by mycologists Dominique Claude Mossebo and Leif Ryvarden. The type was collected in the Dja Faunal Reserve in Cameroon, where it was found fruiting on fallen dead hardwood branches.
