Revision of species previously reported from Brazil under Morganella

Abstract

In our study, seventy specimens from Brazilian herbaria, as well as from NY and PDD, identified as Morganella, were analyzed. They included the paratype of M. mexicana and holotypes of M. arenicola, M. albostipitata, M. compacta, M. nuda, M. rimosa. Specimens were studied morphologically and used for DNA extraction and amplification of ITS and LSU nuclear ribosomal DNA. New sequences were obtained and compared with homologous sequences from GenBank. As a result of these analyses, a new species and six new combinations are proposed. Morphological review and discussion are provided for the species from Brazil.
