The names of 14 species of fossil fungi are validated, two recognized by Kar, one by Rao, and 11 by Nandi et al. The repositories of their holotypes were not specified by the original describing authors, and this validating information is provided herein. All names and their validating descriptions/diagnoses are ascribed to their original authors. These new species names are: Diporisporites giganticus R. K. Kar, Hypoxylonites bhubanensis B. Nandi & S. Banerjee, H. elsikii B. Nandi & S. Banerjee, H. minimus B. Nandi & S. Banerjee, H. neogenicus B. Nandi & S. Banerjee, H. subrotundus B. Nandi & S. Banerjee, H. thindii B. Nandi & A. Sinha, Kalviwadithyrites saxenae M. R. Rao, Lirasporis elongatus R. K. Kar, Spirotremesporites ellipticus B. Nandi & S. Banerjee, S. longiletus B. Nandi & S. Banerjee, S. miocenicus B. Nandi & S. Banerjee, S. reniformis B. Nandi & S. Banerjee, and S. tertiarus B. Nandi, S. Banerjee & A. Sinha. The genus name Kalviwadithyrites M. R. Rao is also here validated, together with the name of its single species, K. saxenae M. R. Rao. The species mentioned above belong to Xylariaceae, Microthyriaceae, and Fungi Imperfecti (Amerosporae and Dictyosporae).
