Leptotheca Schwägr. This southern hemisphere genus, treated in the Aulacomniaceae by both Brotherus (1924) and Sainsbury (1955), was later placed using morphological, cytological, and phytogeographic criteria in the Rhizogoniaceae by Churchill & Buck (1982). More recently Bell et al. (2007) have performed a large-scale molecular phylogenetic analysis using mitochondrial and chloroplast markers from genera placed in several families, including the Aulacomniaceae and Rhizogoniaceae. Their strict consensus tree placed Leptotheca in a strongly supported clade including the genus Orthodontium, and they proposed its transfer to the Orthodontiaceae. Goffinet et al. (2009) have accepted this placement, which we follow here.
