Abstract

Three strains of a xerophilic species were isolated from house dust and honey in Japan. A molecular phylogenetic analysis based on the combined dataset for four regions (internal transcribed spacer rDNA, calmodulin, β-tubulin, and RNA polymerase II second largest subunit) revealed that the strains formed an independent lineage, sister to classified in section . Morphological comparisons show that the strains differ from in three aspects: (i) the size of cleistothecia, as well as the surface structure and size of ascospores, (ii) the ability to grow on Harrold’s agar and dichloran 18 % glycerol agar, and (iii) the lack of conidiophore formation on potato dextrose agar +20 % NaCl. These strains could be clearly distinguished from all known section species. Therefore, we consider it to be a novel species and propose the name sp. nov. (NBRC 115547).
