<abstract xmlns="http://www.w3.org/1999/xhtml"><p> Rusts (Fungi, Basidiomycota, Pucciniomycotina, Pucciniomycetes, Pucciniales) are one of the most important causal agents of diseases and they are infecting many plants including cereals and field crops, vegetables, trees and many ornamentals.

The most significant fruit tree rust pathogen is the genus Gymnosporangium. The literature review shows quite limited scientific information about this genus and its species. Studies have mainly focused on some stages of the pathogen development cycle, which are significant for the spread of diseases - uredo and teleito stages. Special attention of the review was paid to European pear rust (caused by G. sabinae (Dicks.) G.
