Abstract

Punctelia subrudecta s. str. and Punctelia ulophylla comb. nov.They differ in several morphological characters, most notably in the colour andpruinosity of the margin. Both species occur sympatrically, often together on onetree. A third species, Punctelia perreticulata, is known in Europe only from the Mediterranean.
