Serpula himantioides its relation to "S. lacrymans." "Serpula himantioides" has a heterothallic tetrapolar mating system. This means it requires the growth and conjugation of two mating types, determined by the expression of one or more alleles of two unlinked mating loci, for sexual reproduction. "Serpula himantioides" is commonly found in the wild, while "S. lacrymans" is rarely found in the wild and is generally found on lumber in buildings and construction. Serpula himantioides Serpula himantioides is a species of fungus that causes damage to timber referred to as dry rot. It is a basidiomycete in the order Boletales. It has been found
Serpula lacrymans environments, the Himalayas, Northern California, the Czech Republic and east Asia. A recent study on the evolutionary origin and spread of this species using genetic markers (amplified fragment length polymorphisms, DNA sequences and microsatellites) on a worldwide sample of specimens suggested the existence of two main lineages, a nonaggressive lineage found in North America, and an aggressive lineage found on all continents, both in natural environments and buildings. "Serpula lacrymans" is considered to be the most damaging destroyer of indoor wood construction materials in temperate regions. In the United Kingdom alone, money spent by building owners rectifying damage caused by
