The species composition of class Dothideomycetes in the forest plants communities of the steppe zone of Ukraine has been studied. It includes 43 species from 26 genera, 20 families, 6 orders from 2 subclasses and group Incertae sedis. In the taxonomic structure of the investigated species composition it was established predominance of the subclass Pleosporomycetidae, of the order Pleosporales, the families Leptosphaeriaceae, Lophiostomataceae and Mycosphaerellaceae, and also genus Leptosphaeria. We have established the ecological structure of mycobiota and consortial connections with 33 species of plants from 25 genera 11 families. In the ecological structure it was marked the dominance of saprotrophs and xylotrophs. We analyzed the characteristics of habitat distribution of species in communities 3 types of vegetation. A comparison of the taxonomic spectra of Dothideomycetes of forest and steppe communities of the heath zone has been performed.
