About Mycena amicta (Fr.) Quél.
Young Mycena amicta specimens are distinctly blue, and this blue color fades into brownish tones as the mushroom ages. The cap starts out shaped conical to convex, becomes flatter when the mushroom matures, and grows to a maximum diameter of 1.8 cm, or 3⁄4 of an inch. The cuticle of the cap is peelable. The gills are spaced closely together, and the stem is covered in powdery hairs. These mushrooms grow in small groups. They are found on the trunks of broadleaved trees, and are especially common in the Pacific Northwest growing around rotted conifer wood. On the West Coast, they can be found from May through November, while further east they appear between July and September.
