Phenotypic and genotypic characters of strains of Neosartorya spinosa and related taxa were analysed. N. spinosa, Neosartorya botucatensis and Neosartorya paulistensis had identical partial beta-tubulin and calmodulin gene sequences and could not be differentiated on macro- and micro-morphological characteristics, including by scanning electron microscopy. Based on partial beta-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).
对棘孢新萨托菌及相关分类单元菌株的表型和基因型特征进行了分析。棘孢新萨托菌、博图卡新萨托菌和圣保罗新萨托菌具有相同的部分β-微管蛋白和钙调蛋白基因序列，在宏观和微观形态特征上无法区分，包括通过扫描电子显微镜观察。基于部分β-微管蛋白和钙调蛋白基因序列以及子囊孢子形态，区分出两个不同的类群，并将其作为新物种提出。新种细裂新萨托菌具有具微瘤的子囊孢子，有两个弯曲的嵴和两个明显的赤道小突起环。新种韩国新萨托菌具有具皱纹至弱网状的子囊孢子，有两个常弯曲的嵴，但没有赤道小突起环。细裂新萨托菌的模式菌株为CBS 117721T（=NRRL 35589T=KACC 41657T），韩国新萨托菌的模式菌株为CBS 117059T（=NRRL 35590T=KACC 41659T）。
