A survey of mitochondrial DNAs from over 225 Neurospora and related fungal isolates from around the world uncovered three new homology groups of mitochondrial plasmids, two divergent subgroups of the Fiji plasmid family, and extended previous data about plasmid distribution patterns. Newly-discovered circular plasmids, Java and MB1, and the linear Moorea plasmids, were found in relatively-few isolates. A large proportion of isolates (51%) were found to have these or previously-discovered plasmids in the Varkud, kalilo, LaBelle, or Fiji families. Plasmids in most families were found in isolates worldwide and distributed nearly randomly with respect to species. As many as three types of plasmids were found in single isolates, and plasmids typically were found alone or in pairs in a random, independent pattern. The regional clustering of some plasmids was independent of species, providing a strong argument that horizontal transfer of plasmids occurs frequently in nature. Some plasmid families were much more diverse than others. The Fiji plasmids are a superfamily composed of distinct subgroups defined by degrees of cross-hybridization. Between some subgroups there were large regions of non-homology.
