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 boats in many coastal areas around the world. They are found at depths ranging from intertidal to at least 800 meters. Predators include predatory starfish such as the Ochre Sea Star ("Pisaster ochraceous"). "Serpula" has lived since the Cretaceous period, according to fossils found in the Cretaceous Black Creek Formation of North Carolina. The funnel-shaped, symmetrical peristomium is fused with the prostomium to form the head, at the anterior end of the body. Worms of the genus "Serpula" have two photoreceptors or "eyespots" on the peristomium. The prostomium bears a branchial "crown", a specialized mouth appendage which resembles a fan
