Monilinia is a genus of fungi in the family Sclerotiniaceae.

[1] Monilinia fungi are pathogens to Rosaceae and Ericaceae and often cause major losses to crops.

The genus is sometimes divided into two sections based on whether they possess disjunctors - these are small structures in mature fungi that help with spore dispersal.

[2] Most studies of the fungi focus on their pathogenic effects toward apples, pears and other fruits.
