Aspergillus section Aspergillus contains economically important, xerophilic fungi that are widely distributed in nature and the human environment and are known for their ability to grow on substrates with low water activity. The taxa were revised based on sequence data from four loci, PCR fingerprinting, micro- and macromorphology, and physiology. The number of taxa was reduced to 17 species, all of which can be distinguished with sequence data from either the caM or RPB2 locus. The original description of A. proliferans was supplemented by a description of its teleomorph. This species seems to be relatively common and often has been confused with A. glaucus. In addition, green sporulating isolates of A. niveoglaucus isolated from food and several other substrates are indistinguishable in phenotype from A. glaucus. A dichotomous key based on ascospore size and ornamentation and the ability to grow at specific combinations of temperature and water activity is provided for identification of species. In response to recent changes in the botanical code, we transferred the Eurotium species to Aspergillus and selected one name for each species.
曲霉节包含经济上重要的、嗜干性真菌，广泛分布于自然界和人类环境中，以能够在低水活度的基质上生长而闻名。基于来自四个基因座的序列数据、PCR 指纹图谱、微观和宏观形态以及生理学，对分类群进行了修订。分类群的数量减少到 17 个种，所有这些种都可以通过来自 caM 或 RPB2 基因座的序列数据来区分。补充了对 A. proliferans 及其有性型的描述。该物种似乎相对常见，经常与 A. glaucus 混淆。此外，从食品和其他几种基质中分离出的绿色产孢的 A. niveoglaucus 分离株在表型上与 A. glaucus 无法区分。提供了一个基于分生孢子大小和装饰以及在特定温度和水活度组合下生长能力的二歧式钥匙，用于鉴定种。为响应植物学代码的最新变化，我们将 Eurotium 物种转移到 Aspergillus 中，并为每个物种选择了一个名称。
