Abstract

The paper deals with 28 species of the genus Phaeographis occurring in India and Sri Lanka (Ceylon). Two new species-P. nilgiriensis, P. hypoglaucoides-and two new varieties-P. platycarpa var. indica and P. marcescens var. megaspora-have been described. Graphis extrusula Stirt. has been reduced to a variety of Phaeographis extrusa (Stirt.) Zahlbr. and P. megistocarpa f. rotundata Leight. has been considered conspecific to P. megistocarpa (Leight) Mull.-Arg.
