Species occurrence observations are increasingly available for scientific analyses through citizen science projects and digitization of museum records, representing a largely untapped ecological resource. When combined with open-source data, there is unparalleled potential for understanding many aspects of the ecology and biogeography of organisms. Here we describe the process of assembling a pan-European mycological meta-database (ClimFun) and integrating it with open-source data to advance the fields of macroecology and biogeography against a backdrop of global change. Initially 7.3 million unique fungal species fruit body records, spanning nine countries, were processed and assembled into 6 million records of more than 10,000 species. This is an extraordinary amount of fungal data to address macro-ecological questions. We provide two examples of fungal species with different life histories, one ectomycorrhizal and one wood decaying, to demonstrate how such continental-scale meta-databases can offer unique insights into climate change effects on fungal phenology and fruiting patterns in recent decades.

通过公民科学项目和博物馆记录的数字化，物种出现的观测值越来越多地用于科学分析，这表示很大程度上未开发的生态资源。当与开源数据结合使用时，就有无与伦比的潜力来理解生物的生态学和生物地理学的许多方面。在这里，我们描述了组装泛欧洲真菌学元数据库（ClimFun）并将其与开放源数据集成以在全球变化的背景下推进宏观生态学和生物地理学领域的过程。最初，横跨9个国家/地区的730万种独特的真菌物种子实体记录已被处理，并组装成600万种10,000多个物种的记录。这是用于处理宏观生态问题的大量真菌数据。
