Dry rot species of fungi cause brown rot decay, preferentially removing cellulose and hemicellulose from the timber leaving a brittle matrix of modified lignin. The term "dry rot" is somewhat misleading, as both species of fungi "Serpula lacrymans" and "Meruliporia incrassata" require an elevated moisture content to initiate an attack on timber (28–30%). Once established, the fungi can remain active in timber with a moisture content of more than 20%. At relative humidities below 86 percent, growth of "Serpula lacrymans" is inhibited, but it can stay dormant at relative humidities down to 76 percent. These relative humidities correspond to equilibrium moisture contents
The Center for Art in Wood the medium of wood, a permanent collection of over 1,000 pieces and a host of educational programs and workshops. The Center also houses a research library, artists files, and a museum store. A series of publications documents the Center's work and highlights premier artists working in the field of wood turning and art in wood.
