Phonetic: Stem-file-ee-um

Stemphylium is reported to be a known type I allergen found mainly in the temperate northern hemisphere on dead and living plants, soils, moist wood, and cellulose materials; rarely found growing indoors, but has been isolated from air filters and dust samples. It can be weakly parasitic or saprophytic on a wide variety of plants, and can cause leaf spots. Stemphylium is not known to be a human pathogen, but sinus infections (phaeohyphomycotic sinusitis) and respiratory disorders have been reported. Conidia are dark conidia, with cross and longitudinal septa, variable in shape, frequently globose, broadly ellipsoid, or ovoid, and often constricted at major septum. Colonies are considerably rapid growing, cottony; light brown or olive-green to black in color. Culture - Potato dextrose agar, 20° – 25°C, 7 – 10 days.
