Macrofungi are distinguished from other fungi by their spore-bearing fruit bodies (mushrooms, conks, brackets). These fungi are critical in forests, causing disease, and wood and litter decay, recycling nutrients, and forming symbiotic relationships with trees. This guide is intended to assist in identifying macrofungi and provide a description of the ecological functions of some of the most frequently encountered macrofungi in aspen-birch, northern hardwood, lowland conifer, and upland conifer forests in the Midwest and Northeast.
