The structure and diversity of wild grass spike-inhabiting Fusarium communities are not well understood. Fifteen common, non-cultivated grasses were surveyed across two years, regions, and land uses for spike-dwelling Fusarium spp. Eleven fungal species were identified from 857 isolates, including two, F. camptoceras and F. lactis, not recorded previously in New York state or on grass hosts. Species diversity and community structure varied by year and region. Land use and host community did not influence Fusarium communities, and no species-specific grass-Fusarium associations were detected. Fusarium communities were divided into two categories, those dominated by F. graminearum and those dominated by F. sporotrichioides. The community formation process is relevant to disease prediction and toxin monitoring in cropping systems as well as to land management practices at the intersection of agricultural and natural spaces.

野草尖刺镰刀菌群落的结构和多样性尚未得到很好的了解。在两年的时间，区域和钉住镰刀菌属的土地用途中，共调查了15种普通的非栽培草。从857株分离物中鉴定出11种真菌，其中包括2个Camptoceras和F. lactis，这是以前在纽约州或草场上未曾记录的。物种多样性和群落结构随年份和地区而变化。土地利用和寄主社区没有影响镰刀菌群落，也没有发现任何物种特异性的草-镰刀菌协会。镰刀菌群落分为两类，即以禾本科镰刀菌为主的和以孢子孢子虫为主的。社区形成过程与作物系统中的疾病预测和毒素监测以及农业和自然空间交叉处的土地管理实践有关。
