The results of studying the diversity of aphyllophoroid fungi in „Kreidova flora” branch of the Ukrainian Steppe Nature Reserve of National Academy of Sciences of Ukraine (Donetsk region, Ukraine) are presented.

The records of 17 species are new for the Steppe natural zone of Ukraine. Eleven species (Hyphodontia gossypina, Merismodes stipitatus, Resupinatus poriaeformis, Phlebia tremelloidea that Sistotremastrum suecicum; Amyloxenasma allantosporum, Paullicorticium pearsonii, Sistotrema octosporum, Trechispora confinis, Tr. kavinioides and Vararia ochroleuca) are firstly repor­ted from Ukraine. Six latter listed of them were collected in the cretaceous pine forest on wood or debris of the relict Pinus sylvestris var. cretacea. Taking info account three species known from previons research area but not recorded in aur study, the total list of aphyllophoroid fungi in „Kreidova flora” reserve territory at present comprises 144 species.
