Recent collections on leaves of a leguminous host, Dimorphandra mollis, in Mato Grosso, Brazil, led to the discovery of a new species of Johansonia, described here as J. chapadiensis. Based on DNA sequence data of the nuclear ribosomal DNA (LSU), Johansonia is revealed to represent a member of Dothideomycetes, Capnodiales. Although its family could not be resolved, it clustered basal to Schizothyriaceae and Mycosphaerellaceae, and could well represent a species of Saccardiaceae. DNA sequence data of other members of Saccardiaceae would be required, however, to confirm this classification. } }
