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
Atromentin 4-HPP to observe the formation of atromentin. This was followed by characterization of the enzyme GreA in "Suillus grevillei", six (InvA1-6, of which InvA1, 2 and 5 were functional) in "Paxillus involutus", and NPS3 from "Serpula lacrymans". In addition, there is another adjacent and conserved gene encoding for an alcohol dehydrogenase/oxidoreductase whose function is unclear. In most cases the clustered biosynthetic genes are found orthologous in basidiomycetes. A common promoter motif was found shared between the atromentin synthetase and aminotransferase of 23 different atromentin-producing basidiomycetes that was in almost all cases absent from the alcohol dehydrogenase, indicating co-regulation of the
