🔬 Morphology
Cap
Volvariella hypopithys
Cap 2-3.5 cm, bell-shaped at first, then flattened with a small umbo in the center. White, with a matte, silky surface. Sometimes with fine radial fibers. The margin is thin and slightly torn in mature mushrooms.
Silky rosegill
Cap 7-18 cm, egg-shaped or bell-shaped at first, then expanding to conical with an umbo. White or cream, ochre-brown in the center, with silky, fibrous scales in a radial pattern. Silky to the touch, with a matte sheen. The margin is often fringed with remnants of the veil.
Hymenophore
Volvariella hypopithys
Gilled hymenophore. Gills free (not attached to the stem), moderately spaced. White at first, turning brownish-pink with age from the color of the spores. Spore print pink or pinkish-brown — typical of the genus.
Silky rosegill
Gilled hymenophore. Gills 6-12 mm wide, free (not attached to the stem), crowded. White at first, turning pink with age, then pinkish-brown. Spore print pink — a key feature.
Stem
Volvariella hypopithys
Stem 3-5 cm tall, 2-4 mm thick, slender, cylindrical, white, smooth. No ring. At the base there's a dense white volva hugging the stem tightly, like a little sac.
Silky rosegill
Stem 7-19 cm tall, 1-2.5 cm thick, central, cylindrical, slightly thickened toward the base. White, smooth. No ring. At the base there's a large, sac-like white or grayish volva that hugs the stem tightly, with a wide upper rim.
Flesh
Volvariella hypopithys
The flesh is thin, white and delicate. It doesn't change color when cut. The texture is very fragile — the mushroom breaks at the slightest touch.
Silky rosegill
The flesh is white, firm in young mushrooms, quickly yellowing and turning watery with age. It may turn slightly yellow when cut. It doesn't keep — use it on the day you pick it.
Smell
Volvariella hypopithys
No distinct smell, faintly mushroomy. Indistinct taste. Don't taste it — its edibility is unknown.
