Botrytis sp. |
Mitosporic fungus. Hyphomycetes. Teleomorph (sexual state): Botryotinia (Ascomycete). | |
| Distribution | Where Found | Mode of Dissemination |
| Ubiquitous. Primarily in temperate and subtropical regions. Approx. 30 species. |
Soil, stored and transported fruit and vegetables. Plant pathogen and saprophyte on flowers, leaves, stems, fruit. Leaf rot on grapes, strawberries, lettuce, cabbage, onions. /span> | Dry spore. Wind. Also liberated by rain splash. |
| Allergen | Potential Opportunist or Pathogen | Potential Toxin Production |
| Type I allergies (hay fever, asthma). Type III hypersensitivity pneumonitis: Winegrower's lung. |
Very rare agent of keratomycosis. No recorded human cases of infection. | None known. |
| Growth Indoors | Industrial Uses | Other Comments |
| May be found in conjunction with indoor plants. Aw=0.93-0.95 (minimum for various species). |
None known. | Mostly parasitic on higher plants. "Gray-mold," called "noble rot" on wine grapes. |
| Characteristics: Growth/Culture | Notes on Spore Trap Recognition | Notes on Tape Lift Recognition |
| Grows well on all general fungal media. Colony spreads easily over the surface of the petri dish. May form black sclerotia. | Fairly distinctive, frequently with a visible inner cell wall, and an attachment point at one end. Spores are slightly pigmented. | Distinctive, especially if spore bearing structures are present. |
