PhyML analysis of 191 nrLSU sequences within the Omphalotaceae using 100 bootstrap replicates. Clades were collapsed to better show broad relationships. Species names in blue represent /marasmiellus (Wilson and Desjardin 2005). Species names in red represent /gymnopus (Wilson and Desjardin 2005). The major clades reported in Mata et al. (2007) are overlaid in blue. Section Perforantia is indicated in green.
