Andaman and Nicobar Islands of India are relatively underexplored for fungal diversity. From the studies conducted from Andaman region, a few new species and new records have been documented.is characterized by superficial ascomata, or beneath the host periderm, thick carbonaceous walls with central ostioles, brown fusiform ascospores, hyphomycetous or ceolomycetous anarmophs. In the present paper, we introduce two new species, viz. and and report two new records i.e and .

Fungal genus Diatrype is the type of the family Diatrypaceae, Xylariales, Sordariomycetes. During our fungal exploration in Andaman Islands, India (2015–2018), we encountered six fungi belonging to the genus Diatrype. The literature survey suggested that these fungi,viz. D. buteae M.S. Patil & S.D. Patil, D. ilicina Lar. N. Vassiljeva & S.L. Stephenson, D. stigma (Hoffm.) Fr, D. stigmaoides Kauffman, D. subundulata Lar. N. Vassiljeva & H.X. Maand D. syzygii Narendra & V.G. Rao are new records from Andaman Islands, India. The fungal species are reported and illustrated in this paper with morphological descriptions.
