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
Mycelial cord uninfected parts. The cords of some wood-rotting fungi (like "Serpula lacrymans") may be capable of penetrating masonry. The mechanism of the cord formation is not yet precisely understood. Mathematical models suggest that some fields or gradients of signalling chemicals, parallel to the cord axis, may be involved. Rhizomorphs can grow up to in length and in diameter. Mycelial cord Mycelial cords are linear aggregations of parallel-oriented hyphae. The mature cords are composed of wide, empty vessel hyphae surrounded by narrower sheathing hyphae. Cords may look similar to plant roots, and also frequently have similar functions; hence they are also called
