Stigonema tagorum Sp. Nov. (Stigonemataceae, Cyanoprokaryota) from a Stone Monument of Santiniketan, West Bengal, India

Abstract

Cyanobacteria/Cyanoprokaryotes are primary components of the microbial bio-films colonizing on different culturally important stone monuments. Their diversity and eco-physiology was always emphasized as they cause weathering of their substratum leading to disfigurement of the monuments. In the present communication, a novel Stigonematacean species, i.e., Stigonema tagorum is described from a stone monument (Gandhi Statue) in Santiniketan, West Bengal. The taxon has a distinguished type of true branching and cellular morphometry which differentiates it from its resembling taxa.

Keywords

Stigonema tagorum, Cyanoprokaryote, Monuments, Santiniketan.
