Abstract

The article focuses on delimiting species boundaries between the lichenized fungi species pair Pseudocyphellaria glabra and Pseudocyphellaria homoeophylla using restriction site-associated DNA sequencing (RADseq). Despite their morphological and chemical similarity, these species differ in reproductive strategy and geographic distribution, with P. homoeophylla restricted to New Zealand and P. glabra having a broader circum-Antarctic range. Genome-scale RADseq data from 53 individuals revealed that the two species form distinct, well-supported genetic lineages, although some evidence of admixture exists among New Zealand populations. The study demonstrates the utility of RADseq in resolving species boundaries in closely related lichenized fungi and supports maintaining P. glabra and P. homoeophylla as separate taxa.
