The description, illustrations, and data concerning distribution and location of herbarium collections of two species new for the mycobiota of Ukraine – Trichonectria anisospora (Lowen) Lowen and Xenonectriella leptaleae (J. Steiner) Rossman & Lowen, are presented. Ukrainian samples of Trichonectria anisospora are shown to have considerably larger spores than typical material ((15.6–)18.03–21.07×(5.6–)6.2–7.1(–7.3) vs. 14.5–17×4–6.5(–7) µm). The species of Xenonectriella genus is demonstrated for the territory of Ukraine for the first time. Keywords: Western Ukraine, new genus, Trichonectria anisospora , Xenonectriella leptaleae.
