木霉属；被定义为包括Hypocrea的变形，先前放置在Gliocladium和Verticillium中，具有细长的花柱和不规则分枝的分生孢子。提出了木霉的剖面分类方法，分为以下5个剖面：Trichoderma剖面、Longibrachiatum Bissett剖面、Saturnisporum Doi et al剖面、Pachybasium (Sacc.) stat. 11。，下皮囊节。乳木霉是下皮囊部分的典型。木霉组的种有狭窄而弯曲的分生孢子和分枝，分枝和花梗不拥挤，经常成对，很少在一个轮生中有三个以上的成分。厚基科，包括具有高度分叉的分生孢子的种，通常聚集成紧密的束或脓疱，并且具有相对短的，宽的分枝，在拥挤的垂直花序中具有膨胀的雌蕊。下皮区可容纳下皮的变形木霉，有渗出的分生孢子，少分枝的分生孢子和圆柱形到钻形的分生孢子。讨论了现有木霉种、种聚集体和一些变形木霉在5个剖面中的位置，并提供了区分木霉剖面的关键。
The genus Trichoderma Pers.:Fr. is defined to include anamorphs of Hypocrea, previously placed in Gliocladium and Verticillium, having elongate phialides and irregularly branched conidiophores. A sectional classification is proposed for Trichoderma recognizing the following five sections: section Trichoderma, section Longibrachiatum Bissett, section Saturnisporum Doi et al., section Pachybasium (Sacc.) stat.nov., and section Hypocreanum sect.nov. Trichoderma lactea sp.nov. is described, typifying section Hypocreanum. The species in section Trichoderma have narrow and flexuous conidiophores and branches, with branches and phialides uncrowded, frequently paired, and seldom with more than three elements in a whorl. Section Pachybasium, includes species with highly ramified conidiophores that are often aggregated into compact fascicles or pustules and with relatively short, broad branches bearing inflated phialides in crowded verticils. Section Hypocreanum accommodates Trichoderma anamorphs of Hypocrea that have effuse conidiation, sparingly branched conidiophores, and cylindrical to subulate phialides. The placement of existing Trichoderma species, species aggregates, and some anamorphs of Hypocrea in the five sections is discussed, and a key is provided to differentiate the sections of Trichoderma.
