title: <i>Сircinaria ucrainica</i> sp. nov., a new species from sand dunes of the Lower Dnipro valley (Ukraine)
abstract: Abstract During a recent expedition of the Eurasian Dry Grassland Group in the steppes of southern Ukraine, we discovered on sand dunes a new sterile crustose aspicilioid lichen with rhizomorphs. It is described here as new to science under the name Circinaria ucrainica ( Megasporaceae ). The new combination Circinaria reptans (Looman) Khodos. &amp; Darmostuk is also proposed. Circinaria ucrainica is characterized by small grey areoles with a net of dark grey to brownish spicate prothalline tips
