Species in the genus Aspergillus have been classified primarily based on morphological features. Sequencing of house-hold genes has also been used in Aspergillus taxonomy and phylogeny, while extrolites and physiological features have been used less frequently. Three independent ways of classifying and identifying aspergilli appear to be applicable: Morphology combined with physiology and nutritional features, secondary metabolite profiling and DNA sequencing. These three ways of identifying Aspergillus species often point to the same species. This consensus approach can be used initially, but if consensus is achieved it is recommended to combine at least two of these independent ways of characterising aspergilli in a polyphasic taxonomy. The chemical combination of secondary metabolites and DNA sequence features has not been explored in taxonomy yet, however. Examples of these different taxonomic approaches will be given for Aspergillus section Nigri.
种属青霉属的物种主要基于形态特征进行分类。在青霉的分类学和系统发生学中,也使用了家用基因的测序,而外生代谢物和生理特征的使用则较少。似乎有三种独立的方法可用于青霉的分类和鉴定:形态学结合生理学和营养特征、次生代谢产物分析和 DNA 测序。这三种鉴定青霉物种的方法通常指向同一物种。这种共识方法可以初步使用,但如果达成共识,建议在多相分类学中至少结合两种独立的方法来描述青霉。然而,次生代谢物和 DNA 序列特征的化学组合在分类学中尚未得到探索。将为青霉属黑孢组提供这些不同分类方法的例子。
