Human interactions with fungi the weather, and in the case of dry rot caused by "Serpula lacrymans", also of timbers in largely dry houses. Some wood-decay fungi such as the honey fungi, species of "Armillaria", are parasites of living trees, attacking their roots and eventually killing them, and continuing to decompose the wood when they are dead. Honey fungus is a serious horticultural pest, as it can spread from tree to tree by long strap-shaped rhizomorphs in the soil. Fungi are important crop pathogens, as they reproduce rapidly, affect a wide range of crops around the world, cause some 85% of plant diseases, and
Serpula vermicularis tube is fabricated by the glandular ventral shields on the other thoracic segments, where calcium is mixed with an organic secretion to make a paste. This is formed into shape by a collar found just behind the first segment, the prostomium. "Serpula vermicularis" is a filter feeder and extends its radioles to catch phytoplankton and detritus. The radioles also act as gills. Blood is pumped in and out of these with the flow direction alternating in a single set of vessels. The blood is then pumped through a ventral blood vessel to the tip of the abdomen before returning through
