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 the mouth. While they are primarily feeding structures, the radioles also serve as respiratory organs. The radioles of different "Serpula" species are typically red, pink, or orange in color, with white transverse bands. Astaxanthin, a carotenoid pigment, is responsible for the bright red color of the crown of "S. vermicularis". There are usually about 40 radioles in an adult. One of these radioles, called an "operculum", is a highly specialized structure located on the dorsal part of the head. The operculum consists of a long, thick stalk with a cartilaginous, cone-shaped plug at the distal end. This plug can be
