Chroogomphus rutilus, commonly known as the brown slimecap or the copper spike, is a species of fungus in the Gomphidiaceae family. First described scientifically as Agaricus rutilus by Jacob Christian Schäffer in 1774, it was transferred to the genus Chroogomphus in 1964 by Orson K. Miller, Jr. The fungus lives ectomycorrhizally with Pinus species, and is found in Europe and North America. The fruit bodies are edible but not highly regarded. Gomphidius viscidus is an old synonym of this mushroom.

Omphalotus nidiformis, or ghost fungus, is a gilled basidiomycete mushroom most notable for its bioluminescent properties. It is known to be found primarily in southern Australia and Tasmania, but was reported from India in 2012 and 2018. The fan or funnel shaped fruit bodies are up to 30 cm (12 in) across, with cream-coloured caps overlain with shades of orange, brown, purple, or bluish-black. The white or cream gills run down the length of the stipe, which is up to 8 cm (3 in) long and tapers in thickness to the base. The fungus is both saprotrophic and parasitic, and its fruit bodies are

Chroogomphus is a genus of fungi commonly known as pine-spikes or spike-caps, based on the shape of the mushrooms and because they often grow in association with pines. The genus is distributed throughout the Northern Hemisphere, including North America and Eurasia.

Omphalotus japonicus, commonly known as the tsukiyotake (月夜茸), is an orange to brown-colored gilled mushroom native to Japan and Eastern Asia. It is a member of the cosmopolitan genus Omphalotus, the members of which have bioluminescent fruit bodies which glow in darkness. A 2004 molecular study shows it to be most closely related to a clade composed of Omphalotus nidiformis of Australia, Omphalotus olivascens of Western North America and Omphalotus olearius of Europe. Omphalotus japonicus is poisonous. Its consumption results in acute nausea and vomiting for several hours. It is often

Pleurotus populinus, the aspen oyster mushroom, is a gilled fungus native to North America. It is found on dead wood of aspen and cottonwood trees (genus Populus). Although morphologically similar to Pleurotus ostreatus and Pleurotus pulmonarius, it has been shown to be a distinct species incapable of cross-breeding. P. populinus is reported to be edible. Unlike P. ostreatus, which fruits in the autumn and winter, P. populinus fruits in late spring and summer.

Pleurotus cystidiosus, also known as abalone mushroom and maple oyster mushroom, is an edible species of fungus in the family Pleurotaceae, described as new to science by mycologist Orson K. Miller Jr. in 1969. It can be cultivated, with spores and growing kits being available commercially. Antromycopsis macrocarpa (or A. broussonetiae) is the anamorphic form of this species.

Leucopholiota decorosa is a species of fungus in the mushroom family Squamanitaceae. It is commonly known as the decorated pholiota. It was first described by American mycologist Charles Horton Peck as Agaricus decorosus in 1873, and the species has been transferred to several genera in its history, including Tricholoma, Tricholomopsis, Armillaria, and Floccularia. Three American mycologists considered the species unique enough to warrant its own genus, and transferred it into the new genus Leucopholiota in a 1996 publication. It is distinguished by its fruit body which is covered with

Chroogomphus tomentosus, commonly known as the woolly pine spike, is a species of mushroom in the family Gomphidiaceae. It is endemic to western North America.

Omphalotus olivascens, commonly known as the western jack-o'-lantern mushroom, is an orange to brown-colored gilled poisonous mushroom endemic to the North American west coast. It has several lookalikes including Cantharellus cibarius.

Chroogomphus vinicolor, commonly known as the wine-cap Chroogomphus or the pine spike, is a species of mushroom in the family Gomphidiaceae. The fruit bodies have reddish-brown, shiny caps atop tapered stems. The gills are thick, initially pale orange before turning blackish, and extend a short way down the length of the stem. Distinguishing this species from some other similar Chroogomphus species is difficult, as their morphology is similar, and cap coloration is too variable to be a reliable characteristic. C. vinicolor is differentiated from the European C. rutilus and the North American

Xeromphalina brunneola is a species of agaric fungus in the family Mycenaceae. Found in the western United States where it grows in dense clusters on debarked conifer logs, it was described by mycologist Orson K. Miller in 1968. The type collection was made by Miller near Priest River, Idaho, in September 1964. The mushroom has a dull orange, convex to nearly flattened cap measuring 0.6–15 mm (0.02–0.59 in) in diameter. The orange-buff gills are narrow, closely spaced, and decurrently attached to the stipe. Spores are elliptical, smooth, amyloid, and measure 5.5–6.6 by 2.5–3.0 μm.

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

Pseudotulostoma is a genus of fungi in the family Elaphomycetaceae. The genus contains two species; one found in Guyana and one in Japan.

Lentinellus montanus is a species of agaric fungus in the family Auriscalpiaceae. It is found at high elevations in the Pacific Northwest region of North America, where it fruits singly or in clumps on decaying conifer wood.

Hebeloma aminophilum, commonly known as the ghoul fungus, is a species of mushroom in the family Hymenogastraceae. Found in Western Australia, it gets its common name from the propensity of the fruiting bodies to spring out of decomposing animal remains.

Chroogomphus ochraceus is a species of fungus from the family Gomphidiaceae. Known for its close association with conifer trees–especially pines, it is often referred to as the "pine spike" or "spike cap" fungus. C. ochraceus was originally identified as a species limited to the Pacific Northwest because of its display of distinct yellowish colors, but recent research has concluded that this species is widespread across North America and that it is genetically distinct from Chroogomphus rutilus, which is limited to Europe.

Omphalotus mangensis is a species of agaric fungus in the family Marasmiaceae. Found in China, the fruit bodies of the fungus are bioluminescent.

Leucopholiota is a genus of fungi in the family Squamanitaceae. Basidiocarps (fruit bodies) are agarics (gilled mushrooms}. Two species are currently known, both from north temperate areas: Leucopholiota decorosa and Leucopholiota lignicola.
