Epiphytotic development of the rust fungus Endophyllum sempervivi was recorded in May 2016 in the cemetery of Borzova village (Volhynian Region, Ukraine) on Jovibarba globifera, a host species and genus new for Ukraine. In northern Europe (Belgium, Denmark, Ireland, Netherlands, Norway, Sweden, UK), USA (northeastern states) and Canada (Ontario) E. sempervivi occurs beyond the area of natural distribution of Sempervivum and Jovibarba; however, it is apparently absent in Morocco, Spain south of the Pyrenees, Italy south of the Alps and in west Asia (the Caucasus) despite the presence of indigenous species of Sempervivum. A list of all localities in which E. sempervivi was recorded in Ukraine is provided. The article is illustrated by micrographs obtained by scanning electron microscopy.

Keywords: Jovibarba, Sempervivum, rust fungi, distribution, morphology
