Phlebia tremellosa (formerly Merulius tremellosus), commonly known as trembling Merulius or jelly rot, is a species of fungus in the family Meruliaceae. It is a common and widely distributed wood-decay fungus that grows on the rotting wood of both hardwood and conifer plants.

Bridgeoporus is a fungal genus in the family Polyporaceae. A monotypic genus, it contains the single polypore species Bridgeoporus nobilissimus, first described to science in 1949. Commonly known both as the noble polypore and the fuzzy Sandozi, this fungus produces large fruit bodies (or conks) that have been found to weigh up to 130 kilograms (290 lb). The upper surface of the fruit body has a fuzzy or fibrous texture that often supports the growth of algae, bryophytes, or vascular plants. This species is found in the Pacific Northwest region of North America where it grows on large (at

Panellus pusillus is a species of fungus in the family Mycenaceae. A widely distributed species, it has been recorded in Australia, Asia, Europe, North America, and South America. The fungus was first given its current name in 1975, but has been known by many names since French physician and mycologist Joseph-Henri Léveillé first described it as Gloeoporus pusillus in 1844. A recent molecular phylogenetic study explored the diversity and phylogeny of Panellus, and used species like P. pusillus to identify five new poroid species from China in the genus. The mushroom develops into flat and

Laetisaria is a genus of fungi in the family Corticiaceae. Basidiocarps (fruit bodies) are effused, corticioid, smooth, and grow as plant pathogens on grasses or agave leaves, or as lichenicolous fungi on lichens, or on dead wood. Laetisaria fuciformis is of economic importance as the cause of "red thread disease" in turfgrass.

Steccherinum tenue is a hydnoid crust fungus of the family Steccherinaceae. It is found in the southern United States, where it grows on decaying angiospermous wood. The fungus was described as a new species in 1981 by mycologists Harold Burdsall and Karen Nakasone. The type, found growing on grape plants (Vitis), was collected in Great Smoky Mountains National Park (Tennessee) along the Rainbow Falls Trail. Steccherinum tenue has also been found on maple (Acer). The fungus is characterized by its thin grayish-yellow fruit bodies with grey to bluish-grey margins, a lack of rhizomorphs, and a

Phanerochaete arizonica is a species of fungus. It is a plant pathogen that infects Platanus species. Due to some uncertainty in its phylogenetic placement, it is also sometimes referred to as Grandiniella arizonica

Phanerochaete allantospora is a plant pathogen infecting Platanus species.

Laetiporus gilbertsonii is a species of polypore fungus in the family Fomitopsidaceae.

Laetiporus conifericola is a species of polypore fungus in the family Fomitopsidaceae. It is found in western North America ranging from California to Alaska, where it grows as a plant pathogen on conifer trees, particularly fir, spruce, and hemlock. Fruit bodies of the fungus comprise overlapping pore-bearing plates, measuring collectively up to 60 cm (24 in) across, and up to 4 cm (2 in) thick. Their color ranges from bright orange to salmon orange on the upper surface of the cap and stipe, with a yellow pore surface on the cap underside. Spores are egg-shaped, smooth, hyaline

Hebeloma arenosum is a species of mushroom in the family Hymenogastraceae.

Geopora sepulta is a species of fungus belonging to the family Pyronemataceae. It is an uncommon European species. The first accepted record for Britain was a specimen collected in Kent in 1995. This fungus forms a rounded ascocarp underground on sandy loam soils. This fruiting body remains subterranean for most of the year but breaks the surface in the spring to form a creamy-grey cup (apothecium) up to 4.5 cm across and 3 cm tall. It usually occurs in small groups.

Armillaria nabsnona is a species of fungus in the family Physalacriaceae. The species is found in the west coast of North America, Hawaii, and Japan, where it grows on decaying hardwoods, particularly species of alder. Its fruit bodies have convex to flattened orange-brown caps up to 7 cm (2+3⁄4 inches) in diameter, brown stipes, and whitish to pinkish-tan gills.
