Abstract
Three strains of novel oleaginous yeast species were isolated from soil samples collected in Shiga Prefecture, Japan. The sequences of the internal transcribed spacer (ITS) region and the D1/D2 region of the large subunit (LSU) of the rRNA genes indicated that these novel yeast species are members of the genus Hannaella. The results of molecular phylogenetic analysis indicated that strains 38-3 and 8s1 were closely related to Hannaella oryzae. They differed by 10 nucleotide substitutions and one gap (1.77 %) in the D1/D2 region of the LSU of the rRNA genes and by 17-18 nucleotide substitutions and 10-11 gaps (5.45-5.85 %) in the ITS region. Strain 51-4 differed from the type strain of the most closely related species, Hannaella pagnoccae, by 26 nucleotide substitutions (4.46 %) in the D1/D2 region of the LSU of the rRNA genes and by 20 nucleotide substitutions and six gaps (5.42 %) in the ITS region. The names proposed for these previously undescribed species are Hannaella oleicumulans sp. nov. and Hannaella higashiohmiensis sp. nov.

Abstract
During a survey of floricolous yeasts in Portugal, a basidiomycetous yeast representing a novel species in the genus Hannaella was isolated in Portugal from the flower of Lantana camara, an ornamental exotic species native to Central and South America. A combination of phylogenetic analyses of DNA barcode sequences used in yeast molecular systematics, namely the D1/D2 domain and the complete internal transcribed spacer (ITS) region supported the recognition of a new species of Hannaella, that we designate Hannaella floricola sp. nov. (ex-type strain PYCC 9191T=CBS 18097T). Although the assignment of the new species to the genus Hannaella was evident, the detection of its closest relatives appeared more problematic. Nevertheless, our analyses suggested that H. floricola sp. nov. belongs a clade that also includes H. coprosmae, H. oryzae and H. surugaensis, together four candidate novel species. In addition we provide the molecular identification of several unidentified strains whose D1/D2 and ITS sequences are available from GenBank.

Abstract
In this study, the mitogenome of Hannaella oryzae was sequenced by next-generation sequencing (NGS) and successfully assembled. The H. oryzae mitogenome comprised circular DNA molecules with a total size of 26,444 bp. We found that the mitogenome of H. oryzae partially deleted the tRNA gene transferring cysteine. Comparative mitogenomic analyses showed that intronic regions were the main factors contributing to the size variations of mitogenomes in Tremellales. Introns of the cox1 gene in Tremellales species were found to have undergone intron loss/gain events, and introns of the H. oryzae cox1 gene may have different origins. Gene arrangement analysis revealed that H. oryzae contained a unique gene order different from other Tremellales species. Phylogenetic analysis based on a combined mitochondrial gene set resulted in identical and well-supported topologies, wherein H. oryzae was closely related to Tremella fuciformis. This study represents the first report of mitogenome for the Hannaella genus, which will allow further study of the population genetics, taxonomy, and evolutionary biology of this important phylloplane yeast and other related species.
