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 (fungus) composing the family Serpulaceae. It is thought that the common ancestor was saprotrophic,and that ancestor to the latter two genera became mycorrhizal. Using molecular clock analysis, the split between "Austropaxillus" and "Serpula" has been estimated to have occurred about 34.9 mya, roughly coinciding with the separation of South America and Australia from Antarctica. The number of species is uncertain – the two species "S. lacrymans" and "S. himantioides" have been considered to be a single species, or the latter species has possibly five cryptic species within its complex. The members of the genus "Serpula" form flat brown fruit bodies that
