MOLECULAR PHYLOGENY OF THE GENUS KUMANOA (BATRACHOSPERMALES, RHODOPHYTA)(1).

Species belonging to the newly established genus Kumanoa were sampled from locations worldwide. DNA sequence data from the rbcL gene, cox1 barcode region, and universal plastid amplicon (UPA) were collected. The new sequence data for the rbcL were combined with the extensive batrachospermalean rbcL data available in GenBank.

SYSTEMATICS OF THE BATRACHOSPERMALES (RHODOPHYTA)-A SYNTHESIS(1).

Recent molecular and morphological data necessitate a major taxonomic revision of the Batrachospermales, an order of red algae, distributed in freshwater habitats throughout the world. This article is a synthesis of available information with some targeted additional sequence data, resulting in a few relatively conservative taxonomic changes to begin the process of creating a natural taxonomy for the Batrachospermales. To increase the information content of our taxonomic categories, and in particular to reduce paraphyly, we describe one new genus (Kumanoa) and a new section in Batrachospermum (section Macrospora), and we amend the circumscriptions of the family Batrachospermaceae (to include Lemaneaceae and Psilosiphonaceae), the genus Batrachospermum (to exclude the sections Contorta and Hybrida, raised to genus level as Kumanoa), and the sections Aristata, Helminthoidea, and Batrachospermum of Batrachospermum.
