A new genus and species Sheathnema indicum was collected from the leaves and other aerial parts of Pandanus tectorious Sol. ex Park. from the forest areas of Sawantwadi Taluka, Sindhudurg District, Maharashtra. Morphologically this new genus is a synnematous fungus and can be easily differentiated from similar genera such as, Spiropes, Dematophora, Tharoopama,Phaeoisariopsis, Graphium, Leptographium and various other synematous forms in having a dark brown infertile sheath completely covering the synemata at the young stage and partially covering the fruiting body at the mature stage. Besides this it can also be differentiated from other allied genera in having 2–3 septate hyaline to sub hyaline conidia. A description, illustrations and comparison with other allied taxa are presented hereafter.
