About Hydnellum regium K.A.Harrison
Hydnellum regium is a species of tooth fungus belonging to the family Bankeraceae. This species was first described as new to science in 1964 by Canadian mycologist Kenneth A. Harrison. It is found in western North America, and Harrison originally reported collections of the fungus from Oregon, Idaho, and Colorado. Hydnellum regium produces fruitbodies either singly or in groups, growing underneath pine and spruce trees. The fungus produces large, purple-black fruitbodies that form complex rosettes. These rosettes can reach up to 25 cm (10 in) wide and 15 cm (6 in) tall. Hydnellum regium has a brown spore print. Its spores are roughly spherical in shape, tuberculate (covered in rounded bumps), and measure 4.5–6 by 3.5–4.5 μm.
