Golden Conecap

The cap is orangish yellow, and up to 5 cm in diameter. The gills and stipe are beige, the former browning with age. Cap: 0.8-2.2 cm wide or more, starting globose to campanulate before expanding to convex. The surface is smooth but not sticky and is golden yellow to orangy yellow with a deeper colour in the centre of the cap. The cap dries to a chrome yellow colour with paler centre flesh when dry. Gills: Adnate and subdistant with a ventricose bulge. 1.5-3mm wide. They start whitish before developing a cinnamon colour. Stem: 2.5-6.5 cm long and 2-3mm thick and equal across its length or tapering slightly upwards with a slightly bulbous 4-6mm thick base. The interior is hollow and the exterior surface is pruinose with striations and pale yellowish but often discolours to a brownish yellow (fulvous). Flesh: Thin, soft and the same colour as the surface of the cap. Smell: Slight. Taste: Mild. Spores: 10.5-13.5 x 6-7 μm. Elliptical and smooth with a hyaline, apical germ pore. Under the microscope they are yellow. Basidia: 29-37 x 11-12 μm. Four spored. Cheilocystidia: 22-30 x 8-11 μm. Pin-headed and hyaline with a thin wall. Caulocystidia: 22-30 x 7.5-10 μm. Similar to the cheilocystidia.
