🔬 Morphology
Cap
Larch woodwax
Cap 2-5 cm, hemispherical at first, then flattened-convex with a small umbo. Color: bright lemon yellow, sometimes slightly orange at the center. The surface is slimy in wet weather — a thick layer of slime. In dry weather it dries out, turning glossy and waxy yellow.
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
Larch woodwax
Gilled hymenophore. The gills are widely spaced, thick, and decurrent (a typical feature of the genus). White or cream at first, turning yellowish with age. Spore print white.
Ivory woodwax
Gilled hymenophore. The gills are widely spaced, thick, and decurrent (a typical feature of the genus). White at first, taking on a cream tint with age. Spore print white.
Stem
Larch woodwax
Stem 4-6 cm tall, 0.5-1 cm thick, cylindrical. Whitish or pale lemon yellow, with yellow scales or granules. Paler at the top, a more intense yellow toward the base. The surface is moist or slimy. No ring.
