许多种Inosperma在世界各地消费后会导致人类神经中毒。然而，该属植物的毒性种类和毒素含量尚不清楚。本文报道了中国Inosperma属5个新种，即I. longisporum，I.尼瓦莱勒姆岛sphaerobulbosum岛squamulosobrunneum和I.鳞鼻藓基于ITS、nrLSU、rpb 2基因的形态学和分子系统发育分析表明，这些类群是独立的种。编制了中国松籽属17种植物检索表。此外，最臭名昭著的蘑菇神经毒素，毒蕈碱，psilocybin，鹅膏蕈氨酸，蝇蕈醇，在这五个新的物种进行了有针对性的筛选，通过使用超高效液相色谱-串联质谱（UPLC-MS/MS）。结果表明，这五种植物的神经毒素含量各不相同：I. sphaerobulbosum不含测试的神经毒素; I. nivalellum为毒蕈碱阳性; longisporum和I.鳞毛藓醇同时含有鹅膏蕈氨酸和蝇蕈醇，I.在这5个新种中均未检测到裸盖菇素。
Many species of Inosperma cause neurotoxic poisoning in humans after consumption around the world. However, the toxic species of Inosperma and its toxin content remain unclear. In the present study, we proposed five new Inosperma species from China, namely, I. longisporum, I. nivalellum, I. sphaerobulbosum, I. squamulosobrunneum, and I. squamulosohinnuleum. Morphological and molecular phylogenetic analyses based on three genes (ITS, nrLSU, rpb2) revealed that these taxa are independent species. A key to 17 species of Inosperma in China is provided. In addition, targeted screening for the most notorious mushroom neurotoxins, muscarine, psilocybin, ibotenic acid, and muscimol, in these five new species was performed by using ultrahigh-performance liquid chromatography-tandem mass spectrometry (UPLC-MS/MS). Our results show that the neurotoxin contents in these five species varied: I. sphaerobulbosum contains none of the tested neurotoxins; I. nivalellum is muscarine positive; I. longisporum and I. squamulosohinnuleum contain both ibotenic acid and muscimol, and I. squamulosobrunneum only contains muscimol; psilocybin was not detected in these five new species.
