|Mitosporic fungus. Hyphomycetes.Teleomorph (sexual state): Pleospora (Ascomycete).|
|Distribution||Where Found||Mode of Dissemination|
Approx. 6 species.
|Soil, wood, decaying vegetation. Some species found on leaves are plant pathogens.||Dry spore.
|Allergen||Potential Opportunist or Pathogen||Potential Toxin Production|
|Known allergen. Shares allergens with Alternaria.
Type I allergies (hay fever, asthma).
|A rare report of phaeohyphomycotic sinusitis (identification questionable).||Not known.|
|Growth Indoors||Industrial Uses||Other Comments|
|Growth indoors is rare.||Not known.||None.|
|Characteristics: Growth/Culture||Notes on Spore Trap Recognition||Notes on Tape Lift Recognition|
|Grows on general fungal lab media; sporulation may be slow to absent. "Light/dark cycling" may induce sporulation.||Distinctive, not easily confused with other genera, although young spores or spore fragments may be confused with other pigmented muriform spores such as Ulocladium, Alternaria or Pithomyces.||Distinctive and readily identifiable on tape lifts. Although Stemphylium is rarely found growing indoors, it may be seen in dust as part of the normal influx of outdoor particles.|
