Morchella are made from turned end-grain spalted maple. Spalting occurs when fungi invade and digest wood. The line patterns that form are called zone lines. These zone lines are barriers that fungal agents produce in order to protect and delineate their territory as they compete to digest the wood. Zone lines produced by fungi are made of melanin, the same pigment that humans produce in their skin.
The lit component is a wire armature coated with a pigmented wood glue paper mache with shellacked rice paper apertures.
