Abstract
The recently described fungal phylum Entorrhizomycota was established solely for the genus Entorrhiza, species of which cause root-galls in Cyperaceae and Juncaceae. Talbotiomyces calosporus (incertae sedis) shares morphological characteristics and an ecological niche with species of Entorrhiza. We investigated the higher classification of T. calosporus to determine whether it belongs in Entorrhizomycota. Ribosomal DNA sequences showed Talbotiomyces to be a close relative of Entorrhiza and both taxa form a highly supported monophyletic group. Based on molecular phylogenetic analyses and in congruence with existing morphological and ecological data, Entorrhiza and Talbotiomyces represent a deep dichotomy within the Entorrhizomycota. While species of Entorrhiza are characterised by dolipores and occur on monocotyledons, members of Talbotiomyces are characterised by simple pores and are associated with eudicotyledons. This expands the host range of the recently described Entorrhizomycota from Poales to other angiosperms. Higher taxa, namely Talbotiomycet ales ord. nov. and Talbotiomycetaceae fam. nov., are proposed here to accommodate Talbotiomyces.
