In 1859, William Mitten described Stereodon nemoralis (≡ Plagiothecium nemorale) based on the gathering of Sir J.D. Hooker from India. However, the protologue did not indicate any specific specimen or illustration. For the past 50 years, the original material (NY 913349) deposited at the NY Herbarium has been considered as the holotype. However, this assumption has since been found to be incorrect, because in the Herbarium of The Natural History Museum exists other original material of this species (BM 1030713), collected by Hooker. In addition, the specimen from NY Herbarium is in poor condition and its most important diagnostic characters are not visible. In contrast, the material from BM Herbarium is in very good condition, and therefore it is herein designated as the lectotype. Also, the paper describes the resolution of this type, a process complicated by changes that had occurred in the provisions of subsequent botanical Codes.

名称为Stereodon nemoralis Mitt的选型。（Plagiotheciaceae），Polagiothecium nemorale（Mitt。）A. Jaeger的别名。

1859年，威廉·米滕（William Mitten）根据来自印度的贾德·胡克（JD Hooker）爵士的描述，描述了Stereodon nemoralis（≡Plagiothecium nemorale）。但是，该前言并未指出任何具体的标本或插图。在过去的50年中，存放在NY Herbarium的原始材料（NY 913349）被认为是原型。但是，此假设后来被发现是不正确的，因为在自然历史博物馆的植物标本室中，存在着由胡克（Hooker）收集的该物种的其他原始材料（BM 1030713）。此外，纽约标本室的标本状况不佳，最重要的诊断特征不可见。相比之下，来自BM植物标本室的材料处于良好状态，因此在本文中将其称为选型。此外，本文还介绍了这种类型的分辨率，
