Aspergillus section Flavipedes contains species found worldwide in soils and rhizospheres, indoor and cave environments, as endophytes, food contaminants and occasionally as human pathogens. They produce many extensively studied bioactive secondary metabolites and biotechnologically relevant enzymes. The taxa were revised based on phylogenetic analysis of sequences from four loci (B-tubulin, calmodulin, RPB2, ITS rDNA), two PCR fingerprinting methods, micro- and macromorphology and physiology. Section Flavipedes includes three known and seven new species: A. ardalensis, A. frequens, A. luppii, A. mangaliensis, A. movilensis, A. polyporicola, A. spelaeus. The name A. neoflavipes was proposed for Fennellia flavipes a distinct species from its supposed asexual state A. flavipes. Aspergillus iizukae, A. frequens, A. mangaliensis are the most common and widely distributed species, whereas A. flavipes s. str. is rare. A dichotomous key based on the combination of morphology and physiology is provided for all recognized species. Aspergillus section Jani is established to contain A. janus, A. brevijanus, species previously classified as members of sect. Versicolores, Terrei, Flavipedes. This new section is strongly supported by phylogenetic data and morphology. Section Jani species produce three types of conidiophores and conidia, and colonies have green and white sectors making them distinctive. Accessory conidia found in pathogenic A. terreus were found in all members of sects. Flavipedes, Jani. Our data indicated that A. frequens is a clinically relevant and produces accessory conidia during infection.
