Dry rot in ships from various countries. The second was launched in 1810 and, when inspected, the timbers of the upper decks were found to be infected with 'the dry rot'. By 1816 the cost of repairs for this vessel had exceeded the ship's original construction cost. Texts published in the 19th and early 20th centuries also used the term to describe fungi which produced substantial (white colored) mycelium including;"Antrodia (Fibroporia) vaillantii". Eventually, the term "dry rot" came to apply to only one or two fungi the main one being "Serpula lacrymans", in the majority of texts dealing with the subject, predominantly
Serpula tidal fashion. In the central circulatory system, the blood moves anteriorly from the tip of the abdomen to the front of the thorax through a sinus enveloping the alimentary canal, and posteriorly through a ventral blood vessel. The ventral vessel and the sinus communicate with each other by segmentally arranged ring vessels, and by a dorsal vessel, a transverse vessel, and a pair of circumesophageal vessels situated at the anterior end of the thorax. The dorsal vessel in some of the larger serpulids, like "Serpula", possesses a valve and a muscular sphincter, probably to prevent backflow of blood from the
