Hydnellum auratile

Hydnellum auratile is a tooth fungus in the family Bankeraceae. Fruit bodies of the fungus consist of closely grouped, funnel-shaped caps up to 5 cm (2.0 in) in diameter. The caps are initially bright orange with a white rim, and have a felt-like surface. On the cap underside, the hymenium has hanging orange spines with whitish tips. These spines extend a ways down the length of the short stipe. The flesh is orange in both the cap and stipe. In mass, the spores are brown. Microscopically, they measure 4–5 by 3.5–4.5 µm and have short, rounded tubercles on the surface. The widespread Hydnellum aurantiacum is a close lookalike, but can be distinguished by having a white to buff cap, dull orange to brown flesh, and white spines.[2]
