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 divers and other casual observers. Following is a brief description of the cladistics and taxonomic classification of "Serpula": While the higher taxonomy is fairly well understood, the lower taxonomy within the genus "Serpula" is somewhat confusing, and not yet thoroughly worked out. Earlier sources have described as many as 77 different species and subspecies. However, there are currently only 29 recognized species in the genus "Serpula". The number and names of these species may soon change as a result of an ongoing revision of the genus by taxonomists. Worldwide,very common.
