We describe here a new species, Lecidea aptrootii, in Lecidea sensu stricto from Swat Valley, Pakistan. It is most similar to L. fuscoatra in having an areolate thallus and black, lecideine apothecia with a persistent margin. However, L. aptrootii can be readily distinguished by having smaller ascospores (average length 8-10 µm). In phylogenetic analyses, using ITS and nuLSU rDNA sequences, L. aptrootii forms a sister-group relationship to L. grisella, which differs in having a rimose thallus.
