| Abstract | Extensive surveys of mangrove foliose lichens in Caliciaceae and Physciaceae on the Gulf of Thailand revealed eightspecies of the genera Dirinaria, Physcia, and Pyxine. Species density was highest in the mid-intertidal zone (46%), followed bythe landward and seaward zones (31% and 23%, respectively). Fifty-one new internal transcribed spacer sequences weregenerated and the resulting phylogenies based on maximum likelihood and Bayesian approaches yielded monophyletic lineagesof all three genera. However, within the Dirinaria clade formation of polyphyletic assemblages among D. aegialita, D.applanata, and D. picta indicated the presence of homoplasies in certain morphological traits used to characterize them. Toaddress species boundaries of these lichens in Dirinaria picta species complex, methods of DNA barcode-based delineation ofputative species were employed. Additional sampling of the Dirinaria species from elsewhere is required to provide furtherinsight into species delimitation of this heterogeneous genus. |
