Abstract :The lichenicolous fungus Roselliniella lecideae sp. nov. on Lecidea fuscoatra is described from Ukraine. It is characterized by globose ostiolate perithecia, 2-3 septate hyaline periphyses, unitunicate 8-spored asci, and unicellular ellipsoid brown ascospores. This species, close to Roselliniella microthelia , has shorter periphyses, smaller asci, and ascospores, and its hosts. Brackelia lunkei , Henfellra muriformis , Lichenoconium aeruginosum , Lichenohendersonia squamarinae , Lichenostigma dimelaenae , Sphaerellothecium atryneae , Stigmidium epistigmellum , S. stygnospilum , Pronectria xanthoriae , Refractohilum achromaticum , and Zwackhiomyces lithoiceae are reported for the first time from Ukraine. Two species are new for the plains of Ukraine, three are new to the steppe zone of Ukraine, and one species is new to Crimea. A key to the known Roselliniella species is provided.
