摘要描述了产于亚热带西南部的小乳牛一新种--中国。在世界范围内，这是乳杆菌亚属的第三个代表。有彩色乳胶的杰拉第，如亚洲的黑乳鼠和美洲的彼得森乳鼠。在显微镜下，这一新种与灰乳链霉菌不同之处在于菌毛中有薄壁菌丝，而膜中有粗壮的大囊藻。与彼得森乳杆菌相比，细小乳杆菌的片层较远，孢子纹饰较重。尽管在形态上与黑曲霉相似，但在形态上仍与黑曲霉相似。Petersenii分支系统发育分析将细小乳杆菌定位在与L.uyedae相近的位置，在严格的胸膜亚纲中占据基础位置。它是乳杆菌亚种中表现出额外的形态和分子多样性的关键物种。杰拉第。
Abstract Lactifluus parvigerardii, a new species from subtropical southwestern China, is described. Worldwide, this is the third representative of Lactifluus subgen. Gerardii with coloured latex, as in the Asian L. ochrogalactus and the American L. petersenii. Microscopically, this new species differs from L. ochrogalactus in having thin-walled hyphae in the pileipellis and robust macrocystidia in the hymenium. Compared with L. petersenii, L. parvigerardii has distant lamellae and heavily ornamented spores. Despite this morphological similarity to the L. ochrogalactus-L. petersenii clade phylogenetic analysis placed L. parvigerardii close to L. uyedae, taking a basal position in a strictly pleurotoid subclade. It is a key species demonstrating additional morphological and molecular diversity within Lactifluus subgen. Gerardii.
