🔬 Morphology

Cap

Plums and custard

Cap 4-12 cm across, in young specimens convex with an inrolled margin, becoming with age flattened and spreading, with a slightly wavy margin. The cap skin is golden-yellow, densely covered in tiny red-purple fibrous scales, especially in the center, where the scales can merge into a solid red field. Toward the margin the scales thin out and yellow dominates. In old fruit bodies it is mostly yellow-ochre with rusty spots.

Prunes and custard

Cap 3-8 cm across, when young convex with an inrolled margin, with age becoming flat and spread out with a slightly sunken center. The cap skin is dry-fibrous, golden yellow, densely covered in small grey-brown fibrous scales, especially in the center. The base color is golden yellow to yellow-orange.

Hymenophore

Plums and custard

Gilled hymenophore — the gills are notched-attached to the stem, crowded, fleshy, distinctly golden-yellow (one of the brightest yellow hymenophores among the knights). Spore print white to cream — a hallmark of the genus Tricholomopsis (not pink, as in Rhodocollybia).

Prunes and custard
