We describe here a new species, Lecideaaptrootii , 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.
