Sneaking up on fungal evolution: Insights in current concepts of phylogenetic relationships of basal fungi.

Basal fungi encompass a vast variety of terrestric (aplanosporic) and aquatic (zoosporic) fungi. The traditional phyla Zygomycota and Chytridiomycota are now considered polyphyletic and were splitted in the phyla Chytridio-, Blastocladio- and Neocallimastigomycota (comprising the planosporic fungi), and the subphyla Mucoro-, Entomophthoro-, Kickello- and Zoopagomycotina, as well as the trichomycete orders Eccrinales and Asellariales (representing the terrestric fungi). Solving their phylogenetic relationships has become a challenge within recent years. Nevertheless, reliable classification of fungal organisms is an indispensable prerequisite for deep-level phylogeny. Within current subphyla and orders there exist still some genera of polyphyletic origin annihilating the modern concepts of a natural monophyly-based classification scheme. The present study solves contradictions within the zygomycete order Mucorales and revealed promising approaches to the relations within the order Morteriellales. Usage of five distinct loci and comparison of supermatrix and supertree algorithms gave support for new species and relations within anaerobic flagellated gut fungi (Neocallimastigomycota) and to the polyphyly of the order Chytridiales.
