Serpula lacrymans 2016). The genus "Serpula", including "S. lacrymans" and "S. himantoides", is known to produce three classes of chemical compounds: pulvinic acid-type family, himanimides, and polyine acids. Within the pulvinic acid-type family, atromentin-derived compounds include variegatic acid, xerocomic acid, isoxerocomic acid, atromentic acid, variegatorubin, xerocomorubin, and other variants of these pigments. Pulvinic acid-type family pigments were found to be secreted during co-incubation with various bacteria. Serpula lacrymans Serpula lacrymans is one of the fungi that cause damage to timber referred to as dry rot. It is a basidiomycete in the order Boletales.

Serpula vermicularis urchins "Echinus esculentus" and "Psammechinus miliaris", the brittle star "Ophiothrix fragilis", the starfish "Asterias rubens" and the whelk "Buccinum undatum". Red algae grow on the reef in shallow water. The tunicate "Pyura microcosmus" occurs on these reefs, but is seldom seen in other habitats. A large number of cryptic species of microfauna shelter among the tubes. Predators of the worm include sea urchins, starfish, and the wrasses "Crenilabrus melops" and "Ctenolabrus rupestris". Serpula vermicularis Serpula vermicularis, known by common names including the calcareous tubeworm, fan worm, plume worm or red tube worm, is a species of segmented marine polychaete worm
