Powdery Mildew: Identifying Characteristics
| Identifying the injury: | Distorted leaves, defoliation and sometimes reddening or chlorosis of affected leaves. |
| Identifying the fungus: | White mycelia and chains of spores on leaf surfaces. Sometimes black cleistothecia (sexual fruiting bodies) are seen among the white fungal material. Under the dissecting scope the ornamentation and appendages of cleistothecia can be beautiful and are useful in genus-level identification. |
| Susceptible trees: | Many hosts – commonly on laurel oaks, dogwood, maple, crape myrtle and sugarberry in Florida. |
