Abstract

Graphis parvicarpa and Pallidogramme bengalense are described as new to science from India. Graphis parvicarpa is characterized by a striate excipulum, inspersed hymenium, muriform ascospores, and norstictic acid in the thallus. Pallidogramme bengalense is characterized by a striate exciple, muriform, hyaline to pale brown ascospores, inspersed hymenium and no lichen substances in the thallus.
