Since then the focus has mainly shifted to species forming spores singly. For many of the sporocarpic species, no molecular data have been made available and their phylogenetic position has remained unclear. We obtained small subunit ribosomal rDNA and Internal Transcribed Spacer data from specimens of glomeromycotan sporocarps from tropical areas that were assigned to three morphospecies. The complete sequence of the 18S small rDNA subunit sequence, Internal Transcribed Spacers 1 and 2 and 5.8S rDNA subunit was determined from a sporocarp of Glomus fulvum. Partial sequences of the small subunit and the other regions were obtained from Glomus pulvinatum and the newly-described species Glomus megalocarpum. Molecular phylogenetic analyses placed all species analyzed as a monophyletic sister group to the Diversispora spurca/Glomus versiforme clade group ("Glomus group C") within the Diversisporales. The phylogenetic divergence from other known species suggests that this clade may constitute a new genus. These findings will have important consequences for taxon definition in the Diversisporales. They will facilitate identification of these fungi using rDNA sequences within colonized roots or the environment.} }
