This report deals with studies related to phytochemical screening, antioxidant potential and antibacterial activity of two macrolichens Acroscyphus sphaerophoroides Lev., a fruticose lichen and Dirinaria consimilis (Stirton) D.D. Awasthi, a foliose lichen. Qualitative phytochemical analysis showed the presence of alkaloids, terpenoids, saponins, glycosides, tannins and phenols. Acroscyphus sphaerophoroides and Dirinaria consimilis showed relatively antioxidant activity as revealed by DPPH study. A moderate iron chelation has been noted. Both the species showed antibacterial activity against gram-positive bacterial strain Staphylococcus aureus.
