Sporobolomyces sp.

Mitosporic fungus. Hyphomycetes. Teleomorph (sexual state): Sporidiobolus (Basidiomycete).
Distribution Where Found Mode of Dissemination
Ubiquitous;
cosmopolitan.
Approx. 10 species.
Tree leaves, soil, rotting fruit, other plant materials. Associated with lesions caused by other plant parasites. Wet spore. Ballistospores are forcibly discharged during high humidity.
Allergen Potential Opportunist or Pathogen Potential Toxin Production
Known allergen.
Type I and Type III allergies.
Implicated as a cause of dermatitis. Other disease associations are unclear. Not known.
Growth Indoors Industrial Uses Other Comments
Grows on a variety of substrates. Requires very wet conditions. Not known. Sporobolomyces is a basidiomycete (active spore release in times of high humidity). If culturable sampling is conducted on a rainy day, indoor counts may be very high. If repeat sampling is carried out on a dry day at the same location, Sporobolomyces counts may be drastically reduced.
Characteristics: Growth/Culture Notes on Spore Trap Recognition Notes on Tape Lift Recognition
Grows well on general fungal media. Colonies are commonly in shades of peach, pink, and salmon; characteristic satellite colonies are produced around the main colony as a result of forcibly released ballistospores. These spores are counted as basidiospores on spore trap slides. Indistinguishable from other colorless basidiospores.
However, presumptive identification is possible if spores are seen en masse from an area of active growth.
