This study is focused on the taxonomy and evolution of the mushroom genera, Leucoagaricus and Leucocoprinus. These fungi, which are closely related to the grocery store mushroom, are litter decomposers in native forests throughout the world and neotropical leaf-cutter ants grow them for food in the oldest agricultural system on earth. Many species in the USA are still undescribed, despite being abundant and widespread. Species will be investigated and described in California, Hawai'i, Panama and Thailand, identification tools will be developed and results will be published in scientific journals. Relationships between species and positions in their family, the Agaricaceae, will be elucidated with molecular markers and phylogenetic analyses. Taxonomy, classification, and identification infrastructure have an intrinsic impact on fields such as ecology, conservation biology, and agriculture. The work described here will provide identification tools for an important group of saprotrophs that interact directly with tropical ecosystems via carbon cycling, and indirectly with new world tropical agricultural systems via their symbiosis with the attine ants, whose economic impact is huge. The training of students will build the human resources necessary to propel this type of work into the future, while outreach to the non-professional public will broaden support for basic scientific research.

这项研究的重点是蘑菇属，白细胞和白细胞的分类学和演变。这些与杂货店蘑菇密切相关的真菌是世界各地的本地森林中的垃圾分解剂，而新热带叶菜单蚂蚁在地球上最古老的农业系统中种植了食物。尽管丰富且广泛，但美国许多物种仍未描述。将在加利福尼亚，夏威夷，巴拿马和泰国进行调查和描述，将开发标识工具，结果将在科学期刊上发布。物种与家族中的位置之间的关系，琼脂科，将通过分子标记和系统发育分析来阐明。分类学，分类和识别基础设施对诸如生态，保护生物学和农业等领域具有内在影响。此处描述的工作将为一组重要的肉毒杆菌提供识别工具，这些工具通过碳循环直接与热带生态系统相互作用，并通过与Attine Ants的共生性间接与新世界热带农业系统间接相互作用，其经济影响是巨大的。学生的培训将建立必要的人力资源，以推动这类工作进入未来，而向非专业公众推广将扩大对基础科学研究的支持。
