ShearerDEB-9971645Filamentous fungi in the class Ascomycetes play an important role in freshwater habitats as decomposers of aquatic macrophytes and woody debris and deciduous leaves of riparian trees. The freshwater acomycetes have been studied intensively only in the past 25 years and only a few geographical areas have been sampled. In this study, ascomycete species will be collected, isolated, and identified from freshwater habitats along latitudinal and altitudinal gradients in North America from the tundra to New Mexico and from La Selva, Costa Rica. Specimens will be deposited in major herbaria. Cultures will be screened for production of asexual states and bioactive compounds and deposited in major culture collections. Data from this study will provide baseline knowledge of the species-level diversity of freshwater ascomycetes in different types of aquatic habitats necessary for analytical research in ecology, conservation, systematic, and population biology.

ShearerDEB-9971645子囊菌纲的丝状真菌在淡水生境中发挥着重要作用，它们是水生大型植物和木质残骸以及河岸树木落叶的分解者。 仅在过去 25 年里，人们才对淡水子菌进行了深入研究，并且仅对少数地理区域进行了采样。 在这项研究中，将从北美苔原到新墨西哥州和哥斯达黎加拉塞尔瓦沿纬度和海拔梯度的淡水生境中收集、分离和鉴定子囊菌物种。 标本将存放在主要植物标本室。 将筛选培养物的无性状态和生物活性化合物的产生，并存放在主要培养物保藏中心。 这项研究的数据将为生态学、保护、系统和种群生物学的分析研究提供必要的不同类型水生生境中淡水子囊菌物种水平多样性的基线知识。
