|Spore category. Produced by mushrooms, puffballs, shelf fungi, rusts, smuts, and many other fungi.|
|Distribution||Where Found||Mode of Dissemination|
Approx. 1,200 genera.
|Saprophytes and plant pathogens.
Gardens, forests, woodlands.
|Wind; spore release (active mechanism) during periods of high humidity or rain.|
|Allergen||Potential Opportunist or Pathogen||Potential Toxin Production|
Type I allergies (hay fever, asthma).
Type III hypersensitivity pneumonitis: Lycoperdonosis (puffball spores), Mushroom culture hypersensitivity.
|Asexual forms may cause rare opportunistic infections.
The yeast Cryptococcus neoformans is a basidiomycete.
|Mushroom toxicosis (poisoning) is usually a result of ingestion of the following toxins: amanitins, monomethyl-hydrazine, muscarine, ibotenic acid, psilocybin.|
|Growth Indoors||Industrial Uses||Other Comments|
|Serpula lacrimans, the agent of "dry rot," and other fungi causing white and brown wood rot, grow and destroy the structural wood of buildings. Poria incrassata causes a particularly destructive dry rot in buildings.||Many mushrooms are edible, and very important in the food industries.||Occasionally, a benign, non-wood rotting mushroom will fruit inside a building, growing in some unique ecological niche if enough moisture is present.
If mushrooms are found growing indoors we ask clients to submit the entire mushroom for identification.
|Characteristics: Growth/Culture||Notes on Spore Trap Recognition||Notes on Tape Lift Recognition|
|Most Basidiomycetes will not fruit on laboratory media. Many will form arthrospores or sterile mycelia on laboratory media.||Most basidiospores have a distinctive asymmetrical attachment point. Many basidiomycetes have recognizable spores. Serpula, the agent of dry rot, with tan-orange basidiospores, can sometimes be identified on spore trap slides.||Except for the occasional finding of Serpula (above), basidiospores are rarely found on tape lifts, except as a part of normal influx of outdoor spores.|
