The health state of Ginkgo biloba L. and damage caused by microscopic fungi were evaluated over the 2010–2011 time period, in selected localities of Slovakia and Czechia. The trees were assessed and put into two categories of health. Trees in very good (category 1) or good vitality and health with no or only light damage (category 2). A total of seven species of microscopic fungi were identified from samples taken from branches, fruits, and leaves. The following fungal genera were detected: Epicoccum, Fusarium, Alternaria, Phomopsis, Cylindrosporium, Phyllosticta, and Cladosporium. This present study is the first report about microscopic fungi determined on G. biloba for Slovakia.
