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 Vertical ciliary tracts in the grooves between adjacent abdominal segments move particles toward the abdominal fecal groove. Once in the abdominal fecal groove, further ciliary currents transport particulate matter (feces, gametes, etc.) from the depths of the tube, through the thoracic segment to the aperture where it can be released to the sea. Worms of the genus "Serpula" have a very unusual dual circulatory system, consisting of a central system of large vessels through which a continuous true circulation of blood is maintained, and also a peripheral system of small, predominantly blind-ending vessels which alternately empty and fill in a
