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 lacrymans needed to promote "Serpula lacrymans" growth. In terms of aeration "Serpula lacrymans" often grows near ventilation shafts which shows a preference for concentrated oxygen. A moisture content of 30 to 40 percent is its ideal level in wood to promote fruit body formation. It appears that "Serpula lacrymans" requires an environment where both inorganic and organic materials are present. The fungus uses calcium and iron ions extracted from plaster, brick, and stone to aid the breakdown of wood, which results in brown rot. Although it is a common indoor biodeterioration agent, it has only been found in a few natural
