Fibroporia gossypium isolated from an indoor environment in Argentina

Using culture studies and molecular techniques, the brown rot polypore Fibroporia gossypium was identified from a cellar in an old building of Buenos Aires city, the second record of the species in an urban environment in Argentina. The fungus formed large mycelial masses hanging from a wooden support and growing on the walls but did not form basidiomes. The conspecificity of specimens from distant regions is considered and the origin of the present finding is discussed.
