Extract from Wikipedia article: Hydnellum concrescens is an inedible fungus, commonly known as the zoned hydnellum or zoned tooth fungus. As with other tooth fungi, the spores are produced on spines on the underside of the cap, rather than gills. It has a funnel-shaped cap, typically between 2 and 7 cm (0.8–2.8 in) in diameter, which has characteristic concentric zones of color. The cap may also have radial ridges extending from the center to the margins. The spines are pink in young specimens, but turn brown with age.
Hydnellum concrescens is a species of tooth fungus that grows in association with pine trees. In East and Central Texas, it typically fruits in the summer and fall months, producing irregularly shaped, wavy to lobed caps that are 2-6 cm in diameter and range in color from brown to reddish-brown. The flesh is tough and fibrous, and the spines are decurrent, whitish to pale brown, and 1-3 mm long. It can be found growing singly or in groups on the ground in pine-dominated forests, particularly under loblolly and shortleaf pines.
