The genus Talaromyces was described by Benjamin in 1955 as a sexual state of Penicillium that produces soft walled ascomata covered with interwoven hyphae. Phylogenetic information revealed that Penicillium subgenus Biverticillium and Talaromyces form a monophyletic clade distinct from the other Penicillium subgenera. Subsequently, in combination with the recent adoption of the one fungus one name concept, Penicillium subgenus Biverticillium was transferred to Talaromyces. At the time, the new combinations were made based only on phylogenetic information. As such, the aim of this study was to provide a monograph on Talaromyces applying a polyphasic species concept, including morphological, molecular and physiological characters. Based on an ITS, BenA and RPB2 multigene phylogeny, we propose a new sectional classification for the genus, placing the 88 accepted species into seven sections, named sections Bacillispori, Helici, Islandici, Purpurei, Subinflati, Talaromyces and Trachyspermi. We provide morphological descriptions for each of these species, as well as notes on their identification using morphology and DNA sequences. For molecular identification, BenA is proposed as a secondary molecular marker to the accepted ITS barcode for fungi.
拟青霉属由本杰明于1955年描述为青霉属的有性态，其产生覆盖有交织菌丝的软壁子囊果。系统发育信息表明，双轮青霉亚属和拟青霉属形成一个与其他青霉亚属不同的单系分支。随后，结合最近采用的“一种真菌一个名称”的概念，双轮青霉亚属被转移到拟青霉属。当时，新组合仅基于系统发育信息。因此，本研究的目的是应用多相物种概念编写一本关于拟青霉属的专著，包括形态、分子和生理特征。基于内转录间隔区（ITS）、β-微管蛋白基因（BenA）和RNA聚合酶II第二大亚基基因（RPB2）的多基因系统发育，我们为该属提出了一个新的组分类，将88个已接受的物种归入七个组，分别命名为芽孢组、螺旋组、冰岛组、紫色组、近膨组、拟青霉组和糙籽组。我们提供了这些物种的形态描述，以及使用形态学和DNA序列进行鉴定的说明。对于分子鉴定，建议将BenA作为真菌公认的ITS条形码的二级分子标记。
