🔬 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
Gilled hymenophore: the gills are notched (emarginate) at the stem, crowded, fleshy, distinctly yellow. Spore print white to cream.
Stem
Plums and custard
Stem 4-8 cm tall, 0.8-2 cm thick, cylindrical, hollow inside in older specimens. Color: yellowish to yellow-orange, the lower part covered in the same red-purple scales as the cap. Surface dry and fibrous. No ring.
Prunes and custard
Stem 3-7 cm tall, 0.5-1.2 cm thick, cylindrical, hollow in old specimens. Color yellowish to yellow-orange, with fine brownish-fibrous scales on the lower part. Surface dry-fibrous. No ring.
Flesh
Plums and custard
Flesh yellowish, thin and cottony in the cap, rather tough in the stem. No noticeable color change when cut. Smell faintly mushroomy, with a note of wood or rotten wood in mature specimens, taste indistinct or bitterish.
