Paecilomyces variotii

This fungus is known to be heat resistant and can, therefore, be found most commonly in warm and arid environments. It is also very common in air, animal feed, seawater, wood pulp in paper mills, creosote-treated wood, walls, wallpaper, house dust, compost, leather, optical lenses, synthetic rubber, photographic paper, moldy cigars, ink, PVC and kerosene. P. variotii has been known as a pathogen in birds and mammals but also appears to be an important human pathogen and infects the heart, lungs, bones, spleen and soft tissue.
