🔬 Morphology
Cap
Oak woodwax
Cap 4-10 cm, hemispherical at first, then flattened-convex with a broad umbo. Orange-reddish, brick orange, darker at the center. The surface is dry or slightly slimy in wet weather, smooth. The margin is thin and often split in mature specimens.
Ivory woodwax
Cap 4-8 cm (young ones 4-5 cm), hemispherical at first, then convex-flattened with a small umbo. White or creamy white, with a faint yellowish tint, especially at the center. The surface is moist AND slimy in wet weather — a thick layer of clear slime. In dry weather it dries out and becomes smooth.
Hymenophore
Oak woodwax
Gilled hymenophore. The gills are widely spaced, thick, and decurrent (a typical feature of the genus Hygrophorus). White or cream at first, taking on a yellowish or pinkish tint with age. Spore print white.
Ivory woodwax

Stem
Oak woodwax
Stem 4-8 cm tall, 1-2 cm thick, cylindrical, slightly tapering toward the base. White or cream, with a pinkish tint at the top. The surface is dry, with a fine white mealy coating at the top. No ring.
