AppearanceThe cap of the mushroom is 8–12 cm, 80 – 120 mm wide; oval at first, becoming convex, typically with a central bump; sticky; brilliant red or orange, fading to yellow on the margin; typically without warts or patches; the margin lined for about 40-50% of the cap's radius. The red pigment fades from margin toward the center with age. Gills are moderately crowded to crowded, orange-yellow to yellow-orange to yellow. They are free from the stem or slightly attached to it; yellow to orange-yellow; crowded; not bruising. The short gills are subtruncate to truncate. Its stipe or stem is yellow and is decorated with orange fibrils and patches that are the remnants of a felted extension of the limbus internus of the otherwise white volva. The spores measure 7.8 - 9.8 × 5.8 - 7.5 µm and are broadly ellipsoid to ellipsoid and inamyloid. Clamps are common at bases of basidia. Flesh looks whitish to pale yellow; not staining on exposure.
