Nia vibrissa

Nia vibrissa is a species of fungus in the order Agaricales. The species is adapted to a marine environment and is a wood-rotting fungus, producing small, gasteroid basidiocarps (fruit bodies) on driftwood, submerged timber, mangrove wood, and similar substrates. The spores have long, hair-like projections and are widely dispersed in sea water, giving Nia vibrissa a cosmopolitan distribution.

Taxonomy

Nia vibrissa was originally described in 1959 from submerged wood off the coast of Florida. The Latin epithet "vibrissa" (meaning "bristly") refers to the hair-like appendages on the spores. It was initially thought to be a deuteromycete (an asexual or mould-like fungus), but was subsequently found to be the sexual state of a basidiomycete, one of the few such known from the marine environment. Since its fruit bodies are enclosed and its spores are passively released, Nia vibrissa was considered to be a gasteromycete and was placed in its own family within the Melanogastrales, a now obsolete order of terrestrial false truffles.
