P. brevicompactum is a common species worldwide and indoors, occurring in fruit juices, fresh herbs, wall paper, wood, paint, potted plants (particularly strong association), soils, floor dust, mattress dust, caves, freshwater and uranium mines. P. brevicompactum can be xerophilic but sensitive to high-salt conditions. This species also inhibits the growth of several species of soil bacteria, possibly through production of its several mycotoxins (e.g. ochratoxin). P. brevicompactum can be strongly allergenic, but it has not been implicated widely in human disease. However, P. brevicompactum has been isolated from a dog with fungal pneumonia and a deep organ infection in a human.
