Candelariella boikoi is a species of corticolous (bark-dwelling) crustose lichen in the family Candelariaceae. The lichen forms irregular, pale grey to grey-green patches on woody substrates, primarily colonizing the thickened twigs and branch bases of Halocnemum strobilaceum in arid, saline Eurasian semi-desert steppes. Unlike the common egg-yolk lichen Candelariella aurella, C. boikoi lacks a proper cortical skin and instead features a mosaic of algal cells embedded in fungal tissue, with abundant yellow-disced fruiting bodies rimmed by a distinctive golden-yellow margin.

Caloplaca sterilis is a corticolous (bark-dwelling), crustose lichen belonging to the family Teloschistaceae, described in 2011. It is primarily found in steppe and sand dune habitats in the Black Sea region, and has been recorded from Bulgaria, Romania, southwest Russia, and Ukraine. Caloplaca sterilis is characterised by tiny squamules/areoles with contrasting pale greyish-green to greenish soredia. It is easily overlooked and challenging to identify when completely sorediate and sterile (i.e., without any apothecia), especially as its soredia do not contain the typical Sedifolia-grey

Zwackhiomyces polischukii is a species of lichenicolous (lichen-eating) fungus in the family Xanthopyreniaceae. It occurs in Ukraine, where it parasitises the crustose lichens Bacidia fraxinea and B. rubella.
