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 Sea. Species of the genus "Serpula" are common on the west coast of North America from Alaska to Baja California, but are rarely if ever found on the east coast of the United States. They are common in Europe and Africa. Like most tube-building polychaetes, worms of the genus "Serpula" are benthic, sedentary suspension feeders. They secrete and inhabit a permanent calcareous tube attached to hard substrata. As they do not travel outside their tubes, these worms do not have any specialized appendages for swimming. Worms of the genus "Serpula" are commonly found attached to submerged rocks, shells, and even
