Abstract:
This study presents morphological and molecular evidence for the establishment of a new species of Lulworthia based on the evaluation of 11 isolates of Lulworthiales collected in two marinas on the west coast of Portugal initially classified as Lulworthia sp. Maximum likelihood and Bayesian methods were applied to obtain phylogenetic trees for 18S-28S and internal transcribed spacer (ITS1-5.8S-ITS2 = internal transcribed spacer [ITS]) nuc rDNA. The isolates consistently grouped together in a distinct and highly supported clade; all other Lulworthiales analyzed, including the available sequences of Lulworthia spp., segregated separately. These results were supported by common and distinctive morphological characters and enabled recognition and description of the new species Lulworthia atlantica. Two Portuguese isolates were confirmed as Lulworthia cf. purpurea, and two were confirmed as asexual morphs of Zalerion maritima.
