Chromosera cyanophylla is a species of fungus in the genus Chromosera. It is the type species of Chromosera. In young specimens, the slimy cap and stem are yellow, and the gills are of a violet or lilac hue. The species can be found growing in small groups on the wood of conifers. It may resemble Gliophorus laetus. It occurs in Europe and Asia. The species was previously reported from North America, but these reports belong to two other species: Chromosera lilacifolia, which occurs in eastern North America, and Chromosera loreleiae, which occurs in western North America.

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

Chromosera is a genus of fungi in the family Hygrophoraceae. Within the family Hygrophoraceae it is closely related to the genus Gloioxanthomyces. It contains eight brightly colored species showing yellow and/or bluish to violet coloration. Three species are lignicolous, growing on decaying conifer wood. Other species grow on rich organic soil or peat. At least one species can be cultured and displays characteristic yellow and violet pigments in its mycelium. The generic name honors the mycologist Meinhard Moser, and also alludes (chromos) to the distinct coloration of the mushrooms, by

Cleistocybe is a genus of fungi in the family Biannulariaceae. Basidiocarps (fruit bodies) are agaricoid, similar to those of Clitocybe, but with ephemeral traces of a partial veil and decurrent lamellae that are often greyish. The genus is separated on DNA characteristics as well as morphology. Species are known from North America, Europe, North Africa, and Tibet.

Amanita breckonii is a species of agaric fungus in the genus Amanita. It is known from California and Washington, where it associates with Monterey pine, ponderosa pine, and spruce. The species was described as new to science in 1982 by mycologists Harry Delbert Thiers and Joseph Ammirati. The holotype specimen was collected in 1966 on the campus of San Francisco State University by then graduate student Gary Breckon, for whom the species is named.

Clitocybe glacialis is a species of mushroom in the family Tricholomataceae. Formerly known as Lyophyllum montanum, this is a snowbank mushroom, always associated with melting snow along snowbanks and thus glacialis. Originally described by Alexander H. Smith in 1957, this North American species is typically found growing under conifers on mountains.

Amanita constricta, commonly known as the constricted grisette or great grey-sack ringless amanita is a species of mushroom-forming fungus in the family Amanitaceae.

Tubaria punicea is a rare species of agaric fungus in the family Tubariaceae. It is found on the west coast of North America, where it grows on the bases and in hollows of madrone (genus Arbutus).

Cortinarius thiersii is a basidiomycete fungus of the genus Cortinarius native to North America.

Cortinarius smithii, also known as the western red dye mushroom, is an agaric fungus of the genus Cortinarius. Originally named Cortinarius phoeniceus var. occidentalis by American mycologist Alexander H. Smith in 1939, it was renamed to honor Smith in 2012, after molecular analysis revealed that it was genetically different from Cortinarius phoeniceus. It is found in North America. This mushroom is prized as a source of natural dye. According to Mushrooms of the Redwood Coast (2016), it is the "holy grail of California dye mushrooms" and when used with "a neutral pH (around 7) and an alum

Tubaria vinicolor, commonly known as the wine-colored twiglet, is a species of mushroom in the family Tubariaceae. It has a red cap, and is found in cities. It is rare, and found on the Pacific coast of North America. Tubaria vinicolor often grows on woodchips, and has a cortina. This cortina temporarily leaves a ring zone on the stipe. Tubaria vinicolor looks similar to T. punicea. However, T. punicea is typically found in forests, where it grows on madrone wood.

Cortinarius infractiflavus is a species of mushroom-forming fungus in the family Cortinariaceae. It was described as a new species in 1999 from collections made in Wyoming, USA. The mushroom is known to occur North American north of Mexico, Finland, and Bulgaria, where it grows on the ground in boreal and mountainous conifer forests.
