Serpula lacrymans dry rot was at least 150 million pounds per annum. Three variants/strains of S. lacrymans have been sequenced by the Joint Genome Institute (JGI) and its collaborators, and sequence data is available via their MycoCosm portal. One genome is from Serpula lacrymans S7.9 (v2.0). The genome assembly is 42.73 Mbp, with a predicted number of 12789 genes. The second genome is from Serpula lacrymans S7.3 (v2.0). The genome assembly is 47 Mbp, with a predicted number of 14495 genes. The third genome is from Serpula lacrymans var shastensis SHA21-2 (v1.0). The genome assembly is 45.98 Mbp, with a predicted number
Serpula Sea. Species of the genus "Serpula" are common on the west coast of North America from Alaska to Baja California, but are rarely if ever found on the east coast of the United States. They are common in Europe and Africa. Like most tube-building polychaetes, worms of the genus "Serpula" are benthic, sedentary suspension feeders. They secrete and inhabit a permanent calcareous tube attached to hard substrata. As they do not travel outside their tubes, these worms do not have any specialized appendages for swimming. Worms of the genus "Serpula" are commonly found attached to submerged rocks, shells, and even
