Plums and custard

4 to 12 cm in diameter, the surface of the caps of Tricholomopsis rutilans is bright egg-yolk yellow and covered with radial streaks made up of tiny purple scales. Beneath the cap cuticle, the thin flesh is pale yellow. Convex, sometimes with a shallow central depression, the caps expand and become broadly umbonate or occasionally almost completely flat at maturity. Adnate or weakly sinuate, the egg-yolk-yellow gills are broad and crowded. Despite the brightly coloured gills, this mushroom deposits the white spores that are typical of Tricholomas. 1 to 2cm in diameter, the stems range from 4 to 10cm tall and are often curved away from the stump or trunk from which the fruiting body emerges. Pale near the apex, the stems are covered in purple-red scales on a white background. Beneath the stem surface the flesh is pale yellow.
