Two new species of the lichen genus Lecaimmeria are described and illustrated from Pakistan, namely, Lecaimmeria asiatica
and L. crispula. The former taxon is characterized by pale brown to dark brown thallus, up to 2-mm large areoles, fat to
strongly convex apothecial disc, taller hymenium 120–150 µm, apically branched, not anastomosing paraphyses, large conidia
5–7×1.1–1.4 µm, with respect to ecology, and the absence of secondary metabolites, whereas L. crispula can be characterized
by having a light brown to chocolate brown thallus, apothecia having fat to slightly concave discs with wavy margins that
curl inward, a tall hymenium150–180 μm, branched and anastomosing paraphyses, large ascospores 25–33×12–17 μm, and
absence of secondary metabolites. A phylogenetic analysis is provided based on nrITS and nrLSU sequences that support
the separation of both novel species. Comparative analyses with related species of Lecaimmeria are provided to confrm the
status of these species.
