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 vermicularis divided into two. The yellow-coloured body has seven thoracic segments and up to 190 abdominal segments which are protected by the tube. At least four segments with setae (bristles) are found in the thoracic region. "Serpula vermicularis" is cosmopolitan in distribution. It is found in the Pacific and Indian Oceans and the European seaboard of the Atlantic Ocean, but not on the North American coast. It occurs in the intertidal zone and at depths down to . Also along Southern African coast from Olifant's River to Maputo. "Serpula vermicularis" grows on hard substrates. It favours shells of bivalves, boulders and
