Several coprinoid fungi have been identified as promotors of Cremastra appendiculata seed germination, while others appear ineffective. This study aimed to discern which genera within the Psathyrellaceae family exhibit this capability and to identify the most effective coprinoid fungi for the cultivation of C. appendiculata. We collected 21 coprinoid fungi from diverse sources and symbiotically cultured them with C. appendiculata seeds. 9 fungi were found to induce seed germination and support seed development, specifically within the genera Coprinellus, Tulosesus, and Candolleomyces. In contrast, fungi that failed to promote germination predominantly belonged to the genera Coprinopsis and Parasola. Notably, four fungi-Coprinellus xanthothrix, Coprinellus pseudodisseminatus, Psathyrella singeri, and Psathyrella candolleana-were documented for the first time as capable of enhancing C. appendiculata seed germination. Strain 218LXJ-10, identified as Coprinellus radians, demonstrated the most significant effect and has been implemented in large-scale production, underscoring its considerable practical value. These findings contribute vital scientific insights for the conservation and sustainable use of C. appendiculata resources.
已鉴定出几种鹅膏菌真菌可促进蛇头菌种子的萌发，而其他真菌似乎无效。本研究旨在确定哪些粪壳菌科真菌具有这种能力，并确定最有效的鹅膏菌真菌来栽培蛇头菌。我们从不同来源收集了 21 种鹅膏菌，并与蛇头菌种子进行共生培养。发现有 9 种真菌能够诱导种子萌发并支持种子发育，特别是在 Coprinellus、Tulosesus 和 Candolleomyces 属中。相比之下，未能促进萌发的真菌主要属于 Coprinopsis 和 Parasola 属。值得注意的是，首次记录了四种真菌——黄盖鹅膏菌（Coprinellus xanthothrix）、拟散斑鹅膏菌（Coprinellus pseudodisseminatus）、中华鹅膏菌（Psathyrella singeri）和黄鳞鹅膏菌（Psathyrella candolleana）——能够增强蛇头菌种子的萌发。鉴定为光盖鹅膏菌（Coprinellus radians）的菌株 218LXJ-10 表现出最显著的效果，并已在大规模生产中实施，突显其具有相当大的实际价值。这些发现为蛇头菌资源的保护和可持续利用提供了重要的科学见解。
