Аннотация:The successions of communities of cultivated soil fungi from litter decomposition were investigated in urban soils of Moscow (district Tuschino). Litter of Tilia cordata Mill. was incubated during 2 years into Urbic Technosols Humic of residental area and Albic Retisols of urban forest as background soil. There were investigated fungal communities in three ecotopes: the surface of decomposing litter, soil layer touching with litter (0.5 sm), and soil samples as control. The microfungal community arrives with litter into urban soil; it differs from existing in soil. That promotes for enrichment of initially lower fungal diversity of urban soil. During the substrate decomposing the total fungal diversity and the presence of epiphytic and cellulolytic fungi is increased in soil layer contacted with litter. Moreover, in this soil layer a pool of fungi typical for background soil is find out and some of these fungi have not detected in the litter and in control samples of urban soil. The structure of fungal communities from soil layer contacted with litter changes more rapidly and abruptly in urban soil in comparing with its gradual change in background soil. An increase of species diversity and changes of structure of fungal community of soil layer contacted with litter are disappear in urban soil after litter decompose. It is because a one-time litter application is little influence on urban soil mycobiota. It needs a regular addition of litter into soils for decrease of urban soil degradation. In background soil all changes of fungal communities determine by litter’s adding and decomposition are part of soil mycobiota content because of regular litter addition.Key words: urban soil, litter decomposition, microscopic fungi, succession
