The Discovery of Sheathia meghalayensis   Elaya Perumal & Palanisamy, 2026 The world of phycology—the study of algae—just got a little more fascinating. While marine red algae dominate our coastal vocabulary, their freshwater counterparts, the Rhodophyta, represent an ancient and highly specialized evolutionary lineage. (Photo credit: Dr. U Elaya Perumal, Botanical Survey of India) In a paper published in Current Science , researchers U. Elaya Perumal and M. Palanisamy from the Botanical Survey of India announced a major taxonomic breakthrough: the discovery of a distinct, critically endangered freshwater red alga named Sheathia meghalayensis  Elaya Perumal & Palanisamy, 2026 .

  W. A. Setchell N. L. Gardner      I am sure everyone who is into the business of identifying seaweeds must have come across the names, Setchell et Gardner. At least when I described Ulva taeniata from Malvan in 2007, I was curious to know more about these two amazing Phycologists. They together described more than 670 species and infraspecific taxa from at least 110 genera, 40 of which were new to science. Thus the pair remembered for their joint legacy. They were of the same age, had the same interest, and spent their phycological career at the Department of Botany and Herbarium of the University of California at Berkeley. The careers of two men were inextricable; their talents and abilities were in part congruent and in part complementary.  William Albert Setchell was born in Norwich, Connecticut on April 15, 1864, into a family that had deep roots in New England. He had an early interest in natural history in particular Botany. Apart from marine algae, h...
