Shelf fungi (sometimes called Bracket fungi) characteristically produce shelf or bracket shaped fruiting bodies called conks. They are mainly found on trees (living and dead) and coarse woody debris, and may resemble mushrooms. Some form annual fruiting bodies while others are perennial and grow larger year after year. Bracket fungi are typically tough and sturdy and produce their spores, called basidiospores, within the pores that typically make up the undersurface (note the lighter color). In New Hampshire, they tend to grow on the north side of the trees where there is little or no sunlight. These two grew close enough together so that I could catch a top and underneath POV with one photo. Zoom helps a bit. Thanks for stopping by, taking a look and for all your previous favs and comments. They are very much appreciated. Dana
