Phylogenetic placement of the genus Anhellia and the description of A. nectandrae sp. nov.

The phylogenetic position of a new species of Anhellia (Myriangiales) was investigated by analysis of nucleotide sequences of ribosomal large subunit (LSU) and ITS regions. The new sequence was aligned with 28 sequences obtained from GenBank, including four species of Davidiellaceae (Capnodiales) used as outgroup. This study is the first attempt to resolve the placement of the genus Anhellia within Myriangiales. The genus Anhellia was strongly supported in Myriangiaceae by phylogenetic analyses. In addition, A. nectandrae sp. nov., collected on Nectandra rigida from a fragment of Atlantic forest in Brazil, is described, illustrated and a table with morphological features to all known Anhellia species is provided.
