The present taxonomy of the black aspergilli reveals that there are 19 accepted taxa. However the identification of species of Aspergillus section Nigri is often problematic in spite of the existence of numerous methods proposed. An overview is provided of phenotypic and molecular methods to identify the accepted species of the black aspergilli. Colony morphology, conidial size and ornamentation of the ex type cultures is presented in a pictorial overview. The temperature range of all species is given and their growth characteristics on creatine agar and boscalid agar, a medium which was developed as a selective medium for the isolation of A. carbonarius are also shown. The extrolites produced by each species are listed while the response of the Ehrlich reaction is described. The literature on the various molecular methods to be used for species identification is reviewed and a critical evaluation of the usefulness of various techniques and genomic loci for species identification of black aspergilli is presented.

识别黑曲霉的诊断工具。

目前黑曲霉的分类显示有 19 个被接受的分类群。然而，尽管提出了许多方法，但识别黑曲霉属的物种通常是有问题的。概述了用于识别公认的黑曲霉物种的表型和分子方法。前型培养物的菌落形态、分生孢子大小和装饰以图片概述形式呈现。给出了所有物种的温度范围及其在肌酸琼脂和啶酰菌胺琼脂上的生长特征，还显示了一种培养基，该培养基被开发为用于分离炭疽杆菌的选择性培养基。列出了每个物种产生的 extrolites，同时描述了 Ehrlich 反应的响应。
