Among all the regions studied in this study for grouping the most diversified grouping was observed with rpb2 gene. Better homogeneity was observed even with tef-1 region. But among all ITS was established as the best region for grouping of Chaetomium species. | Studies on phylogeny of chaetomium species of India
