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
Nemapogon granella are uniformly greyish-brown and surrounded by a fringe of long hairs. On the head, the adults have a tuft of yellowish-white hairs. The caterpillar larvae eat rotting wood in the wild, though they prefer bracket fungi, usually Polyporales. Their mainstay food included Polyporaceae such as sulphur polypore ("Laetiporus sulphureus"), dryad's saddle ("Polyporus squamosus") or turkey tail ("Trametes versicolor"), as well as Fomitopsidaceae, e.g. birch polypore ("Piptoporus betulinus"). But they have also been found on "Serpula lacrymans" of the quite unrelated Boletales. Larvae in association with humans will feed on a variety of dry organic material, such as dried fruit (e.g.bilberries,
