Tricholoma flavovirens, also known as Yellow Knight has a medium to large cap that is vivid yellow and brown at the centre. The gills are yellow. Tricholoma flavovirens forms a mycorrhizal association with pine trees and is commonly found growing individually, in scattered clusters, or sometimes in larger groups. It thrives in impoverished, sandy soil during the summer and fall seasons.

Cap broadly convex or nearly flat, with an inrolled margin at first; expanding to broadly convex or flat, often with a broad, low, central hump. Pale yellow at first, then greenish-yellow to vivid yellow and usually remaining yellow on the margin but gradually becoming brown from the disk centre outward. The flesh is thick, firm; white or tinged with yellow under the cuticle. Gills pale to bright yellow, notched around the apex of the stem, close, broad. The edges become ragged with age. Stem more or less equal, or enlarged at base; solid or hollowed in age. Surface smooth to fibrillose; pale to light yellow. The stem has no ring. Spore print white.

Microscopic Features: Spores are ellipsoidal, smooth, 5-8.5 x 3-6µm in size, and have a prominent hilar appendage. They are inamyloid.
