Phenotypic and genotypic characters of strains of Neosartorya spinosa and related taxa were analysed. N. spinosa, Neosartorya botucatensis and Neosartorya paulistensis had identical partial 
-tubulin and calmodulin gene sequences and could not be differentiated on macro- and micro-morphological characteristics, including by scanning electron microscopy. Based on partial -tubulin and calmodulin gene sequences and ascospore morphology, two separate groups are distinguished and are proposed as novel species. Neosartorya laciniosa sp. nov. has microtuberculate ascospores with two bent crests and two distinct equatorial rings of small projections. Neosartorya coreana sp. nov. has rugose to weak reticulate ascospores with two often bent crests, but without the equatorial rings of small projections. The type strain of N. laciniosa is CBS 117721T (=NRRL 35589T=KACC 41657T) and the type strain of N. coreana is CBS 117059T (=NRRL 35590T=KACC 41659T).

The GenBank/EMBL/DDBJ accession numbers for the -tubulin and calmodulin gene sequences of the strains examined in this study are shown in Table 1.
A NJ phylogenetic tree based on calmodulin gene sequences and SEM images of ascospores of Neosartorya species are available as supplementary figures in IJSEM Online.
The Mycobank accession numbers for Neosartorya laciniosa sp. nov. and Neosartorya coreana sp. nov. are MB 500233 and MB 500234, respectively (http://www.mycobank.org).
