A conk is the woody fruiting body of the fungus that forms a triangular shape. Other white-rot fungi include the turkey tail, artist's conk, and tinder fungus. While the tree is alive, only sterile mycelial masses are produced (the black exterior conk). The fruiting body of "Fomitopsis pinicola" is called the "conk". The sterile conk is irregularly formed and has the appearance of burnt charcoal. Conk was a hairstyle popular among African-American men from the 1920s to 1960s. But what if Cristy's magic diet pills begin to conk out? "Ganoderma applanatum", the artist's conk, is used as a substrate for drawings. Its conk (fruit body) is known as the red belt conk. Bryophytes or sometimes vascular plants grow on the upper surface of the conk. A single conk usually indicates complete cull. When decay is sufficient to provide enough resources, a new conk may be produced.
