abstract = {A multigene genealogy based on maximum parsimony and distance analyses of the exonic genes for actin (act) and translation elongation factor 1 alpha (tef), the nuclear genes for the small (18S) and large (28S) subunit ribosomal RNA (comprising 807, 1092, 1863, 389 characters, respectively) of essentially all fifty genera of the Mucorales (Zygomycetes) suggests that the Choanephoraceae Schr?ter form a monophyletic group. The monotypic genus Gilbertella Hesseltine, which is classified into the monogeneric family Gilbertellaceae Benny, appears in close phylogenetic relatedness to the Choanephoraceae. The monophyly of the Choanephoraceae is supported by aberrantly from low to higher ranging bootstrap proportions (67 and 98 % in distance and maximum parsimony analyses, respectively), whereas the monophyly of the Choanephoraceae-Gilbertellaceae clade is supported by high bootstrap values (98 and 100 %) proposing that both families can be joined into one family which leads to the elimination of the Gilbertellaceae as a separate family. In order to validate these relationships single-locus Neighbor-joining analyses were performed on nuclear genes of the 18S, 5.8S, 28S and internal transcribed spacer (ITS) 1 ribosomal RNA and the elongation factor 1 alpha (tef) and beta tubulin (btub) nucleotide sequences. The monophyly of the Choanephoraceae-Gilbertellaceae clade could be confirmed in all gene trees. The ultrastructure of sporangia, sporangiola and sporangiospores show several morphological characters (e.g. longitudinal sutures splitting the sporangial walls, striations and polar ciliate appendages on the sporangiospores) which occur only in the Choanephoraceae-Gilbertellaceae clade. Based on these results and reanalysis of other morphological and physiological evidences from the literature, we propose to fuse the two families Choanephoraceae and Gilbertellaceae into one family, the Choanephoraceae.}
