Agaricus aurivellus Batsch, Elench. Fung. Contin. 1 : 153. 1786. Pholiota aurivella Gill. Champ. Fr. 441. 1876.
Pileus 4-13 cm. broad, campanulate to convex, often broadly umboriate, when young more or less uniformly ochraceous-orange to tawny, when mature becoming more uniformly tawny, at first covered with large appressed spot-like scales which may in large part disappear and when wet may become more or less gelatinous, viscid; context yellow; lamellae sinuateadnate or adnate, close, dark-rusty-brown when mature; veil forming a superior, torn, sporestained, partly evanescent annulus; stipe central or excentric, equal or tapering upward, dry, yellowish or yellowish-brown, floccose above the annulus, fibrillose below and increasingly scaly or shreddy downward with fibrillose scales that may become recurved, solid, 5-8 cm. long, 5-15 mm. thick; spores exactly and constantly oblong-ellipsoid, smooth, 7-9.5 X 4-5 ju; cystidia present, often rather rare, brown, sometimes projecting and rather conspicuously sharp-pointed, sometimes imbedded and blunt, 6-8 p. in diameter.
Type locality: Europe.
Habitat: On trunks of living (rarely dead) deciduous or coniferous trees. Distribution: Illinois, Colorado, California, and Oregon; also in Europe.

Pholiota aurivella is a species of fungus in the family Strophariaceae that is found in native forest of New Zealand, southern Canada, and in the United States. It is frequently found in the American West and Southwest, especially in late summer and fall. Most field guides list it as inedible, with one reporting that it contains toxins which cause gastric upset. According to David Arora, the taste resembles "marshmallows without the sugar." It is sticky or slimy when moist and grows in clusters on live or dead trees.

The cap colour is bright to golden yellow, viscid when young with relatively dark scales. The stem is pale, and scaly closer to the bottom.

Pholiota limonella and its subspecies are very similar, seeming to differ only in the spores.
