To obtain an understanding of the phylogenetic relationships among the Georgefischeriales, septation, cellular interactions, teliospores,
basidia, cultures and nucleotide sequences from the 5′ terminal domain of the nuclear large subunit rRNA gene were studied.
Analyses of both morphological and molecular characters yield similar phylogenetic conclusions. The Georgefischeriales are divided
into three groups, corresponding to the Eballistraceae, Georgefischeriaceae, and Tilletiariaceae. The basal dichotomy is between the
Eballistraceae and the branch uniting the Georgefischeriaceae and Tilletiariaceae. The Tilletiariaceae are phragmobasidiate, whereas the
Eballistraceae and the Georgefischeriaceae are holobasidiate. The Eballistraceae differ from the Georgefischeriaceae and Tilletiariaceae in the
lack of the ballistospore mechanism. The systematic position of Tilletiopsis minor is unclear. The Eballistraceae, Eballistra and
Phragmotaenium are proposed as new taxa. The descriptions of the Tilletiariaceae and Jamesdicksonia are emended. Except for Entyloma
majus, E. parvum, Georgefischeria, Jamesdicksonia brunkii, J. obesa, Tilletiaria anomala, and Tolyposporella chrysopognis, the teleomorphic
species of the Georgefischeriales are presented as new combinations.
