[2] Index Fungorum and Mycobank state that the current official name of this species is Melanoleuca yatesii.

[3][4] It is extremely similar to Tricholoma equestre but it grows in mycorrhizal association with Quercus (oak trees and shrubs) rather than with Pinus.

[6] William A. Murrill's original description (of what was then called Melanoleuca yatesii) was "Pileus regular, convex, solitary, 5-8 cm.

broad; surface smooth, glabrous, viscid, sulfur-yellow, becoming brownish at the center on drying, margin concolorous, entire, incurved on drying; context rather thin, white to pale-yellow; lamellae sinuate-adnexed, rather broad, ventricose, not crowded, apparently pale-yellow when fresh, somewhat discolored on drying; spores ellipsoid, smooth, hyaline, 5X3 μ; stipe equal, shining, subglabrous, sulfur-yellow, becoming nearly white when dry, 6-10 cm long, 8-12 mm thick.

"[7] Tricholoma yatesii is named after H. S. Yates, who collected the type species under introduced eucalyptus and endemic Monterey cypress in Berkeley, California.
