Bracket Fungi.

Bracket fungi, or shelf fungi, are among the many groups of fungi. Characteristically, they produce shelf- or bracket-shaped or occasionally circular fruiting bodies called conks that lie in a close planar grouping of separate or interconnected horizontal rows. Brackets can range from only a single row of a few caps, to dozens of rows of caps that can weigh several hundred pounds. They are mainly found on trees (living and dead) and coarse woody debris, and may resemble mushrooms.
