Cap: 3-10 cm broad. Conic to convex, expanding to broadly quickly. Flat with age with a pronounced umbo, surface smooth, viscid when moist, with a separate pellicle. Chestnut to caramel in color, bruising blue to blue black when damaged.

Gills: Ascending, sinuate to adnate, brown. mottled, edges white.

Stem: 90-200 mm long x 3-6 mm thick, silky white, fibrous. Base of stem thickening downwards, often curved.

Spores: 12-13.5 x 6.8m.

Sporeprint: Dark purplish black.

Habitat: Cespitose to gregarious. Fruiting abundantly on decidous woodchips, sandy soils rich in lignicolous debris. Prefers alder chips and/or bark mulch. Found in Gardens in parks and around homes and office buildings.

Distribution: Along the northern coast of Oregon in dune grasses. Also found in Washington and British Columbia.

Season: September to December. A cold weather species

Dosage: Extremely potent. 1 to 2 large mushrooms or 2 to 4 small specimens.

Comment: This species has been successfully transplanted into other mulched areas with similar environments. In 1990, Jochen Gartz, after two years of attempts to grow them outdoors in Leipzig, Germany, was finally able to successfully cultivate a small patch of P. azurescens in his garden. They did not return the following year, nor did they spread into other ares of Leipzig from his patch. Other cosmopolitan outdoor habitats included: small patches in Italy, Austria, Switzerland and in the United States: in New Mexico, Ohio, Wisconsin and Vermont. While this is a good mushroom to transplant, after a few years the patches disappear as the nutrients in the soil and woodchips get eaten up by the mycelia. Furthermore, for some reason or other, no other outdoor natural patches have occurred as a result of these transplanted patches with mycelia from their natural Oregon coastal area habitats.
