As a result of the National Nature Park "Oleshkivski Pisky" microbiota study, 112 species
of fungi and fungi-like protists were found: 18 species are slime molds, 1 – Zygomycota,
32 – Ascomycota and 61 – Basidiomycota representatives. Among them 14 species are
fungicolous, 2 – myxomyceticulous and 1 – lichenicolous. Fungicolous species Hypomyces
albidus Rehm in anamorphous stage Cladobotryum sphaerocephalum (Berk.) Rogerson et
Samuels and myxomycete Amaurochaete tubulina (Alb. et Schwein.) T. Macbr. are
registered in Ukraine for the first time. An interesting record is Patellaria crassispora H.-
O. Baral, nomen provisum, which was also not known in Ukraine till now. We assume that
ascigenous sporification of Mycosphaerella sp., found by us on overwintered needles of
Pinus palassiana D. Don, probably is a still undescribed teleomorph of Dothistroma pini
Hulbary. Slime mould Stemonitopsis microspora (Lister) Nann.-Bremek. registered in the
steppe zone of Ukraine for the first time
