Abstract
Phylogenetic relationships within the Phallales were estimated via combined sequences: nuclear ribosomal large subunit (LSU), second largest subunit of RNA polymerase (rpb2), and mitochondrial ATPase subunit 6 (atp6). The ingroup is represented by 62 taxa comprising 18 genera and 44 species, including members of the Clathraceae, Claustulaceae, Gastrosporiaceae, Lysuraceae, Phallaceae and Protophallaceae. Sixty-one new sequences were generated, including tropical and subtropical taxa. This is one of the first studies discussing the phylogenetic placement of Abrachium, Aseroë, Blumenavia, Gastrosporium, Jansia and Xylophallus. Gastrosporiaceae was demonstrated to be sister to Phallaceae and an emended description of the order is presented. Aseroë was demonstrated to be polyphyletic and as a result, A. arachnoidea is transferred to Lysurus.
