  4. Late season on coniferous forest floor
Edibility: Edible and choice. Slightly peppery, slightly fruity/sweet, firm and always bug free. Populations vary and some may be bitter, which disappears with thorough cooking.
Notes: This is the smaller cousin of Hydnum repandum, which was our November 2010 Mushroom of the Month. It's late season makes it perfect for holiday cooking and mid-winter explorations. It may be difficult to tell the difference between a small Hydnum repandum and a large Hydnum umbilicatum, but it's not important.
