Summary: Recent segregation of 12 genera in the tribe Streblocladieae has updated the taxonomy of certain species belonging to Polysiphonia sensu lato, with new combinations being proposed. Six new additions to the tribe have been made based on morphological and molecular analyses, including the description of a new species and proposal of new combinations. The study also identified additional diagnostic features for two genera within the tribe, providing insights into distribution, diagnostic features for delimiting genera morphologically, and molecular evolutionary relationships.

Summary: The cosmopolitan species of Acrosorium with hook-forming thalli have been merged under the name of Acrosorium ciliolatum after a long and complicated nomenclatural history. Specimens from various locations show intraspecific variation and can be separated into four clades based on rbcL phylogeny. The taxon A. flabellatum exhibits extreme variations in external blade morphology, with the absence or presence of terminal hook-like structures as a distinguishing feature. Further study is needed on European and southern hemisphere specimens and the ambiguous position of California specimens.

Summary: A new species, Fragilaria shirshovii sp. nov., was identified and described based on molecular and morphological investigations. The species was isolated from desalinated water masses in the Gulf of Ob, where river and marine waters mix. The study analyzed the morphology of the species using light microscopy and scanning electron microscopy. The importance rating for this article is 8 out of 10.

Summary: This study reveals a new species, G. khanjanapajiae, in Thailand through morphological and genetic analyses. The species can be distinguished by its dentate blade margin, deep spermatangial conceptacles, and abundant nutritive filaments. Phylogenetically, it is closely related to G. spinulosa from Taiwan. The research highlights the ongoing discovery of Gracilaria diversity and distribution in the tropical Indo-Pacific.

Summary: Neoporphyra kitoi is a newly described species of red algae found in Honshu, Japan. It is distinguished from other similar species by both molecular and developmental characteristics, with the unique feature of new blades arising from rhizoidal cells. Molecular phylogenetic analysis places Neoporphyra kitoi in a clade containing sequences of the genus Neoporphyra.
