Ganoderma oregonense
Murrill, 1908 [1]

Ganoderma oregonense (also known as the west-coast reishi, western varnished conk, lacquer fungus, and/or American ling-chi) is a species of bracket fungus that causes root and butt white rot in conifers in northwestern coastal North America, [2] [3] including California, Oregon, Washington, British Columbia, Yukon, and Alaska. [4] G. oregonense is very similar to Ganoderma tsugae , [5] but G. tsugae is associated with east coast Tsuga (hemlock) rather than west coast conifer. [6] Its been speculated that G. oregonense and G. tsugae might actually be one species, but mycologists just don't know for sure yet. [5]

Western varnished conk has a shiny brown-red-orange and sometimes cream-colored upper surface (often appearing as a color gradient), and white- or cream-colored pores. [3] It can be shaped like a kidney or a fan or a hoof, [7] or like a plate or stack of plates jammed into the side of a log. It fruits annually (rather than perennially), and usually shows up in the fall. [3] They can get quite big, up to a foot in size. [3]

Trees inoculated with G. oregonense end up with spongy, soft insides. [3] It prefers dead red fir but will also accept dead or alive Douglas fir, spruce, hemlock, and pine. [3] When this reishi is found on living trees it is usually consequent to tree wounds, [3] such as bear marks.

According to Paul Stamets, this fungus is edible. [8] This is unusual for a Ganoderma , specimens of which are usually far too tough to be eaten (reishi is often dried, powdered and consumed as a mushroom tea). [8]

This species was originally described by W. A. Murrill as "Pileus reniform, corky, rigid, convex above, plane below, 10 x 17 x 5 cm; surface glabrous, thinly encrusted, smooth, laccate, very lustrous, bay to black, with a deep groove near the margin, which is cream-colored, rounded, smooth, entire, finely tomentose; context punky, white to slightly discolored, homogeneous, with white lines of mycelium near the stipe, 2-3.5 cm. thick; tubes annual, 1 cm. long, avellaneous within, mouths circular to angular, 3 to a mm., edges thin, entire, white to avellaneous; stipe lateral, very thick, short, subcylindric, 2-4 cm long, 3-6 cm. thick, expanding into the pileus, which it resembles in color, surface, and context."

<i>Aureoboletus mirabilis</i> Species of fungus

Aureoboletus mirabilis, commonly known as the admirable bolete, the bragger's bolete, and the velvet top, is an edible species of fungus in the Boletaceae mushroom family. The fruit body has several characteristics with which it may be identified: a dark reddish-brown cap; yellow to greenish-yellow pores on the undersurface of the cap; and a reddish-brown stem with long narrow reticulations. Aureoboletus mirabilis is found in coniferous forests along the Pacific Coast of North America, and in Asia. Unusual for boletes, A. mirabilis sometimes appears to fruit on the wood or woody debris of Hemlock, suggesting a saprobic lifestyle. Despite occasional appearances to the contrary, Aureoboletus mirabilis is mycorrhizal, and forms close mutualistic associations with hemlock roots.

<i>Xerocomellus zelleri</i> Species of fungus

Xerocomellus zelleri, commonly known as Zeller's bolete, is an edible species of mushroom in the family Boletaceae. First described scientifically by American mycologist William Alphonso Murrill in 1912, the species has been juggled by various authors to several genera, including Boletus, Boletellus, and Xerocomus. Found solely in western North America from British Columbia south to Mexico, the fruit bodies are distinguished by their dark reddish brown to nearly black caps with uneven surfaces, the yellow pores on the underside of the caps, and the red-streaked yellow stems. The fungus grows in summer and autumn on the ground, often in Douglas fir forests or on their margins. The development of the fruit bodies is gymnocarpic, meaning that the hymenium appears and develops to maturity in an exposed state, not enclosed by any protective membrane.

<i>Suillus brevipes</i> Species of edible fungus in the family Suillaceae found throughout North America

Suillus brevipes is a species of fungus in the family Suillaceae. First described by American mycologists in the late 19th century, it is commonly known as the stubby-stalk or the short-stemmed slippery Jack. The fruit bodies (mushrooms) produced by the fungus are characterized by a chocolate to reddish-brown cap covered with a sticky layer of slime, and a short whitish stipe that has neither a partial veil nor prominent, colored glandular dots. The cap can reach a diameter of about 10 cm, while the stipe is up to 6 cm long and 2 cm thick. Like other bolete mushrooms, S. brevipes produces spores in a vertically arranged layer of spongy tubes with openings that form a layer of small yellowish pores on the underside of the cap.

<i>Fomes fomentarius</i> Species of fungus

Fomes fomentarius is a species of fungal plant pathogen found in Europe, Asia, Africa and North America. The species produces very large polypore fruit bodies which are shaped like a horse's hoof and vary in colour from a silvery grey to almost black, though they are normally brown. It grows on the side of various species of tree, which it infects through broken bark, causing rot. The species typically continues to live on trees long after they have died, changing from a parasite to a decomposer.

<i>Agaricus hondensis</i> Species of fungus in the family Agaricaceae

Agaricus hondensis, commonly known as the felt-ringed agaricus, is a species of fungus in the family Agaricaceae. The species was officially described in 1912 by mycologist William Alphonso Murrill, along with three other Agaricus species that have since been placed in synonymy with A. hondensis. Found in the Pacific Northwest region of North America, A. hondensis fruits in the fall under conifers or in mixed forests.

<i>Tuber oregonense</i> Species of fungus

Tuber oregonense, commonly known as the Oregon white truffle, is a species of edible truffle in the genus Tuber. Described as new to science in 2010, the North American species is found on the western coast of the United States, from northern California to southern British Columbia west of the Cascade Range. A mycorrhizal fungus, it grows in a symbiotic association with Douglas fir. It overlaps in distribution with the closely related T. gibbosum, but they have different growing seasons: T. oregonense typically appears from October through March, while T. gibbosum grows from January to June. The fruit bodies of the fungus are roughly spherical to irregular in shape, and resemble small potatoes up to 5 cm (2 in) in diameter. Inside the truffle is the gleba, which is initially white before it becomes a marbled tan color. The large, often thick-walled, and strongly ornamented spores are produced in large spherical asci. The truffle is highly prized for its taste and aroma. Some individuals have claimed success in cultivating the truffles in Christmas tree farms.

Pulveroboletus ravenelii, commonly known as Ravenel's bolete or the powdery sulfur bolete, is a species of bolete fungus in the family Boletaceae. Described as new to science in 1853, the widely distributed species is known from Asia, Australia, North America, Central America, and South America. Mycorrhizal with oak, the fungus fruits on the ground singly, scattered, or in groups in woods. Fruit bodies (mushrooms) have convex to flat, yellowish to brownish-red caps up to 10 cm (4 in) in diameter. On the cap underside, the pore surface is bright yellow before turning dingy yellow to grayish brown with age; it stains greenish blue then grayish brown after injury. A cottony and powdery partial veil remains as a ring on the stipe. The mushrooms are edible, and have been used in traditional Chinese medicine and for mushroom dyeing.

<i>Lepiota castaneidisca</i> Species of fungus

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.

<i>Ganoderma sessile</i> Species of fungus

Ganoderma sessile is a species of polypore fungus in the Ganodermataceae family. There is taxonomic uncertainty with this fungus since its circumscription in 1902.
