Serpula himantioides 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 on all continents except for Antarctica. Recent molecular work demonstrates that "S. himantioides" is a species complex including multiple cryptic lineages. The fungus was first described in 1818 by Elias Magnus Fries as "Merulius himantioides". Petter Karsten transferred it to the genus "Serpula" in 1884. "Serpula himantioides" is a fungal pathogen within the division Basidiomycota. It produces thin, resupinate (inverted), membranous fan-like basidiocarps that are brownish in color and
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
