What’s our first thought about fungi? Fungal infections? No doubt certain occurrences of fungus are unpleasant (athlete’s foot, black spot on roses). However fungi are critical to all life, particularly because over 90% of plant species benefit from a symbiotic relation with fungi termed mycorrhiza.
Occasionally fungi in the form of mushrooms are attractive. Following are two examples.

These small mushrooms were growing on wood chip mulch in our garden. They most likely are Coprinopsis lagopus, commonly known as the hare-foot mushroom. These mushrooms last only a few hours before they dissolve into an inky mess.
These large mushrooms were found growing from a standing dead tree in the Chippewa National Forest, near Walker, Minnesota. They are Pleurotus dryinus, or Veiled Oyster mushrooms. This mushroom is most often found growing on decaying wood of oak, ash and beech trees.
