Stemphylium sp. |
Mitosporic fungus. Hyphomycetes.Teleomorph (sexual state): Pleospora (Ascomycete). | |
| Distribution | Where Found | Mode of Dissemination |
| Ubiquitous; cosmopolitan. Approx. 6 species. |
Soil, wood, decaying vegetation. Some species found on leaves are plant pathogens. /span> | Dry spore. Wind. |
| 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. |
