section is macromorphologically distinguished by the collybioid or mycenoid basidiome, which is pink, purple, or violet, and, rarely, reddish-brown or yellowish. It is further characterized by the presence of oxalate crystals in the basal mycelium. The section comprises approximately 40 taxa, of which only five species and one variety exhibit bioluminescence. As part of an extensive study on sect. in Mexico, specimens belonging to this section were collected and subjected to morphological analysis. Sequences from the nuclear internal transcribed spacer (ITS) of nuclear ribosomal DNA, RNA polymerase II large subunit Rpb1 (), and translation elongation factor-1α () were generated to infer the relationships within sect. using maximum likelihood and Bayesian inference. The phylogenetic evidence, along with the macro- and micromorphological features, supported the recognition of five new bioluminescent species within sect. Detailed macro- and micromorphological descriptions, line-drawing illustrations, and light and dark photographs of the new species are provided.
该组在宏观形态上的特征是具有粉褶菌状或小菇状担子果，颜色为粉红色、紫色或紫罗兰色，很少为红棕色或淡黄色。其进一步的特征是在基部菌丝体中存在草酸钙晶体。该组包含约40个分类单元，其中只有5个物种和1个变种具有生物发光现象。作为对墨西哥该组进行的广泛研究的一部分，收集了属于该组的标本并进行了形态学分析。生成了核糖体DNA的核内转录间隔区（ITS）、RNA聚合酶II大亚基Rpb1（）和翻译延伸因子-1α（）的序列，以使用最大似然法和贝叶斯推断来推断该组内的关系。系统发育证据以及宏观和微观形态特征支持在该组内识别出5个新的生物发光物种。提供了新物种的详细宏观和微观形态描述、线条图插图以及明暗照片。
