摘要Inocybes的一些种类。str.在世界各地食用后引起神经毒性中毒。然而，该属中有大量物种尚未对其毒性或毒素含量进行研究。在这项研究中，我们报告了两个新的有毒黄色Inocybs。根据形态特征、系统发育分析和毒素检测结果，对中国产的10种主要产毒种进行了初步鉴定。其中Inocybesquarrosolutea为中国新记录种。我们还描述了一个新种，I.squarrosofulva，这是形态相似的I. squarrosolutea。该新种的特征为菌盖黄褐色，方玫瑰色，菌柄上具明显的环状皮层，担孢子具瘤状，侧囊孢子壁厚壁。采用UPLC-MS/MS法测定了子实体中毒蕈碱的含量，粗解硬珊瑚和黄毛硬珊瑚中毒蕈碱的含量分别为136.4 ± 25.4 ~ 1683.0 ± 313 mg/kg干重和31.2 ± 5.8 ~ 101.8 ± 18.9 mg/kg干重。
Abstract Some species of Inocybes. str. caused neurotoxic poisoning after consumption around the world. However, there are a large number of species in this genus that have not been studied for their toxicity or toxin content. In this study, we report two new toxic yellow Inocybes. str. species from China based on morphological characteristics, phylogenetic analyses and toxin detection. Among the two species, Inocybesquarrosolutea is reported as a newly recorded species of China. We also describe a new species, I.squarrosofulva, which is morphologically similar to I.squarrosolutea. The new species is characterized by its ochraceous squarrose pileus, distinctly annulate cortina on the stipe, nodulose basidiospores and thick-walled pleurocystidia. Muscarine in the fruitbodies was detected by UPLC–MS/MS, the content in I.squarrosolutea and I.squarrosofulva were 136.4 ± 25.4 to 1683.0 ± 313 mg/kg dry weight and 31.2 ± 5.8 to 101.8 ± 18.9 mg/kg dry weight, respectively.
