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 ((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.
Specimens of the rust fungus Uromyces erythronii were recorded on Erythronium dens-canis, a rare species listed in the Red Data Book of Ukraine, in April 2016 near Chemeryntsi village (Lviv Region, Ukraine) and in May 2016 near Zaluzhne village (Zhytomyr Region, Ukraine). An investigation of the Erythronium specimens deposited in the herbaria of vascular plants of Lviv Natural History Museum (LWS) and M.G. Kholodny Institute of Botany (KW) revealed four more samples of this fungus. A list of all localities in which U. erythronii was recorded in Ukraine is provided. The article is illustrated by micrographs obtained by scanning electron microscopy.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
