context_page_description: Hydnellum is a genus of tooth fungi in the family Bankeraceae. Widely distributed in the Northern Hemisphere, the genus contains around 40 species. The fruitbodies of its members grow by slowly enveloping nearby bits of grass and vegetation. There is great variability in the form of Hydnellum fruitbodies, which are greatly influenced by environmental conditions such as rainfall and humidity, drying winds, and temperature. They are too tough and woody to eat comfortably. Several species have become the focus of increasing conservation concern following widespread declines in abundance.
  Hydnellum species produce pigments that have been used to dye textiles. Several chemical compounds—some with unique biological activity—have been isolated and identified from the genus.
  One of the better-known species is the unusual pinkish-white Hydnellum peckii, also known as "strawberries and cream" or as the "bleeding tooth fungus" due to the red droplets that appear on the pinkish or whitish fruitbodies. Another species, H. suaveolens, has a strong odor of anise or peppermint.
context_section_description: Karsten's original 1879 circumscription of Hydnellum contained 19 species. Joost Stalpers included 34 Hydnellum species in his 1993 monograph on the Thelephorales. The tenth edition of the Dictionary of the Fungi (2008) indicated 38 species in the genus.  As of January 2015, Index Fungorum lists 39 species of Hydnellum; a figure which does not include the 12 species transferred into this genus from Sarcodon in 2019 by Larsson et al.
