Helicomyces

A mitosporic mold often encountered on decaying plant matter. The genus name prefix "helico" is derived from the shape of the mold's microscopic structure; certain filaments (sometimes the conidia) curve into a helical path. Reported effects upon human health in the indoor environment are not available at this time. Scientists have shown the interaction of Helicomyces roseus with nitrogen-fixing bacteria to be a vital component of an effective soil enriching system (where sugar cane litter is the decomposition target). Helicomyces lilliputeus has long been known as an important sewage treatment systems decomposer, so it is not unexpected that other members of this genus have been observed living on wood submerged in water.
