Fibroporia vaillantii with a wood moisture content of 40 to 50 percent. In humid atmospheres, the white cotton-like mycelium can grow on wood surfaces and cross inert materials, similar to the true dry rot fungus, "Serpula lacrymans". In newly grown mycelium, fine drops of clear liquid may be present. The optimal temperature for growth is ; it will grow at temperatures between . The fruit body is an irregular white plate with a thickness of 2 to 12 mm. Fibroporia vaillantii Fibroporia vaillantii, also known as mine fungus, white pore fungus, Antrodia vaillantii, Polyporus vaillantii, and various other names is a wood-decaying
Serpula all sabellids and serpulids employ chlorocruorin as an oxygen transport macromolecule, "Serpula" is the only genus that appears to possess both hemoglobin as well as chlorocruorin. Chlorocruorin is an oxygen-binding hemeprotein whose affinity for oxygen is weaker than that of most hemoglobins. A dichromatic compound, chlorocruorin is noted for appearing green in dilute solutions, though it appears light red when found in concentrated solutions. Its structure is very similar to erythrocruorin, each molecule being composed of more than a hundred interlinked 16-17kDa myoglobin-like subunits arranged in a giant complex with a total weight exceeding 3600kDa. This enormous macromolecule is free
