The “Fourth checklist of lichen-forming and lichenicolous fungi of Ukraine”, including 2150 accepted scientific names based on published records as well as analysis of current additions are provided. Current additions include 439 taxa newly recorded for Ukraine after the third checklist of lichens of Ukraine by Kondratyuk et al. (2010) and 262 nomenclatural novelties. Annotations to each taxon of 318 newly recorded to Ukraine are provided in the style of the second checklist by Kondratyuk et al. (1998), i.e. data on phytogeographical regions and administrative districts (oblasts) of Ukraine as well as references to published papers are provided. Among current additions 99 taxa were annotated in the Checklist of lichenicolous fungi of Ukraine by Darmostuk and Khodosovtsev (2017) and consequent references to the latter are provided.
The conclusion confirms the earlier recommendation that national checklists of lichens are to be re-published more often than once a decade.
