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 vigorous pumping movements of the abdomen and also by the activity of the ciliary tracts. The well-developed longitudinal muscles of the body wall of serpulids lack a special blood supply. The body surface in the larger serpulids, like "Serpula", has a rich blood supply, and the water in contact with this surface is constantly renewed. It seems probable that the outer body surface of serpulids serves as a respiratory membrane, supplying oxygen to the underlying muscles by diffusion. The biochemistry of the blood of "Serpula" is especially unusual in that the blood contains not only hemoglobin, but also chlorocruorin. While
