✦ Synopsis
The paper describes the morphology and reproduction of a new species of Symphyonemopsis viz. S. pantii n. sp. isolated from enrichment cultures of a soil sample collected from the campus of Sangeet Samiti, Allahabad (India).
Thalli grow as dark bluegreen, small, wooly patches on soil surface but as cushion-like growths on agar plates. It has a prostrate and erect system. The latter bears secondary branches of almost equal breadth. It possesses both false and true branches.
Usually true branches are reverse V-shaped.
The alga shows formation of hormocysts and akinetes. In old cultures usually the main filament becomes multiseriate.
The crescent-shaped stages of hormocysts are also present here. Cells of the present alga are constricted at the crosswalls. On comparison it was found to come close to Symphyonemopsis katniensis Tiwari et Mitra but differs in certain fundamental characters.
It is, therefore, described as a new species viz. S. pantii n. sp. (Cyanophyta, Stigonematales, Mastigocladaceae).
