Fibroporia vaillantii Fibroporia vaillantii Fibroporia vaillantii, also known as mine fungus, white pore fungus, Antrodia vaillantii, Polyporus vaillantii, and various other names is a wood-decaying fungus which can occur on timber in humid conditions. The fungus causes brown rot of pine wood, in which cellulose and hemicellulose are broken down, leading to brown discoloration and shrinkage of wood. It has been/is sometimes considered to be a fungus causing dry rot, although that term is more often used for wood decay due to a different fungus, "Serpula lacrymans". The fungus grows on wood from coniferous trees, such as pine wood, under damp conditions,
Serpula but comparison with other serpulids suggests it may be between six days and two months, although in other species the period has been shown to vary with season, salinity or food availability, and delayed settling may cause reduced discrimination of substrata during settling (see ten Hove, 1979 for additional references). Worms of the genus "Serpula" are filter feeders, and possess a complete digestive system. Like other polychaetes, "Serpula" excrete with fully developed nephridia.
