Mushrooms intrigue me, particularly the ones that emerge in surprising colors. This one certainly fills that stipulation. Indigo Lactarius (Lactarius indigo).

Mycorrhizal, or having a symbiotic relationship, with pines and oaks. Indigo Lactarius will grow in a large group or a small group, or alone in summer and fall.

Found in North America from the northeast to the southwestern United States, Mexico, Central America, East Asia and in middle of my lane.
