Before heading out to hunt, take a moment to learn some important details that will make your experience enjoyable and risk-free. The best advice you can get during wild edible mushroom foraging in Oregon is to approach with absolute caution.

Mushroom Associations with Trees

Most wild edible mushrooms are mycorrhizal that means they build symbiotic associations with the roots of ectomycorrhizal trees and shrubs. Due to the mushrooms lack the chlorophyll, they are not able to obtain energy from the sun and synthesize carbohydrates (sugars). Instead of this, the fungi use their underground networks of hyphae to receive sugars and other nutrition from the trees. In return, plants obtain minerals and water from the soil via mentioned above networks.

Different mushrooms grow under certain types of trees and prefer a specific climate and soil. Finding the right forest that is suitable for particular species of the fungi is helpful in a successful search and proper identification.

Douglas-fir supports boletes and chanterelles.
Pine is associated with boletes including King boletes, hedgehog mushroom, matsutake, chanterelles, slippery jack, and other suillus.
Under Oak, you can find boletes, chanterelles, blewits, black trumpets, honey mushrooms, and oysters.
Western hemlock host of a number of fungi such as boletes, matsutake, chanterelles.
Sitka spruce is associated with boletes and slippery jack.
Aspen is a common host for oyster mushroom, honey mushrooms, and aspen boletes.
Willow is associated with oyster and honey mushrooms.
Birch supports chanterelles, hedgehogs, and boletes.

Boletes are the safest wild edible mushrooms for the novices. These mushrooms are easy to identify by their appearance and spongy-like surface underside of the cap. Bolete is a broad species of mushrooms that contain many edible species and only a few poisonous or bitter.

It is estimated that over 100,000 metric tons King Bolete mushrooms are consumed worldwide annually. The cost of boletes is high because these fungi are restricted to wild foraging and tend to be the most difficult to cultivate.

They are great for sautéing, frying, or drying.

White Matsutake (Tricholoma magnivelare) or Pine Mushroom in Japanese is highly prized for its spicy cinnamon aroma and unique flavor. In Japan, Armillaria matsutake is the most valuable and expensive fungi and costs up to $500 per pound. The Pacific Northwest matsutake resembles Japanese species though they tend to have a bit different color and texture. In North America, the matsutake (Armillaria ponderosa) is harvested commercially for the local market and for export to Japan.

The white matsutake is widespread in British Columbia, Washington, Oregon, and Northern California, growing on the ground, in sandy soil under pine, hemlock, Douglas fir, madrone, tanoak, and manzanita. In Oregon, matsutake is most abundant in coastal woods and the southern Cascade Range. Also, these mushrooms are found in the Willamette, Umpqua, Deschutes, and Fremont-Winema National Forests.

Before heading into the woods to harvest the matsutake, check rules and regulations for this particular area. Obtain commercial or personal use permits. Non-commercial permits are required in some areas including the national forests.

Cap: Firm, wide, convex, become flat with age, white to yellowish, 2-8 inches (5-20 cm) wide.
Cap's Underside: White gills when fresh, stains brownish with age.
Steam: Thick, fibrous, shape of the base (without bulb or volva). 2-6 inches (5-15 cm) long. White veil, breaks and can disappear when mature.
Flesh: Fibrous.
Habitat: On the ground under conifer trees.
Season: August-November.
Features: Distinctive spicy cinnamon odor.

Caution. Do not confuse matsutake with white Amanita that has a bulb or volva at the steam's base.



Lobster

Wild Edible Mushroom

Lobster is not really a mushroom, but a parasitic mold Hypomyces Lactifluorum that attacks and grows on short-stemmed Russula Brevipes and Lactarius Piperatus. The mold makes the mushrooms malformed and totally changes their appearance. The surface of the mushrooms becomes bright orange or reddish purple. Lobster mushroom has firm meaty texture and fish odor. The mushrooms are excellent for sautéing.

Technically Hypomyces Lactifluorum only parasitizes Russulas and Lactarius species, improving the taste and aroma of the mushrooms. According to some sources, the mold could potentially parasitize a poisonous species. If you cannot confirm the host, avoid the mushroom harvesting.

Cap: Covered by bright orange to reddish mold.
Cap's Underside: Gills are reduced or not visible.
Steam: Solid, covered by bright orange to reddish mold.
Flesh: White and crisp.
Habitat: Widespread in coniferous forests.
Season: Summer through fall.
Caution. Some guidebooks state that the host mushroom can be poisonous, making Lobster mushrooms toxic. But other sources assert that a chance that Hypomyces Lactifluorum attacks any other species is tiny.

Milky Cap belongs to mushrooms of the Lactarius, Lactifluus, and Multifurca genera. Some of the milky caps are excellent edibles and a few are mildly poisonous. The mushroom common name is a reference to the milk-like fluid (latex) that is exuded when the fresh fungus is broken or cut.

One of the popular Lactarius species is Safron Milky Cap or Delicious Milky Cap (Lactarius Deliciosus). This mushroom has been eaten for many hundreds of years and is very popular in China, Japan, West, and East Europe. Can be salted or pickling. Before preserving, milky caps need to be blanched into the salted water. Changing the water twice decreases the possible fungi toxic properties.

Cap: Depressed in the center, orange, zoned with darker orange, 2-6 inches (5-15 cm) wide, staining green when mature.
Gills: Orange, regular, exuding white to yellow milk when cut, staining green with age.
Steam: Orange, short, stout, 2-4 inches (5-10 cm) long.
Flesh: Cream-yellowish, staining geenish.
