Colombia is a country for which one of the highest biodiversity rates is reported, and one of the first in the tropical areas where an effort was made to gather information on indigenous fungi. Nevertheless, mycological data are still scarce and discontinuous, above all on soil fungi. The present study wanted to contribute to unveil the large soil fungal biodiversity in the upper Andean Colombian agro-ecosystems. The studied area is located in the department of Boyacà, considered with a notable economical value, partly devoted to subsistence agriculture. More than 150 described species were revealed in this study, belonging to 5 phyla with Ascomycota representing the dominant taxon. Basidiomycota and Zygomycota are also well represented, dominated by species of the genus Sebacina and Mortierella respectively, mainly distributed in the semi-natural plots (woodland and grassland). Most of the species are reported as first records for Colombia. Some of them are particularly interesting for their conservation significance such as Geoglossum fallax, which is the dominant species in the unimproved grassland plot. The bootstrap-based clustering analysis showed a different distribution of the species in orchards and non-cultivated areas as a possible response of the fungal community to different use of soil in the agro-environment.
哥伦比亚是一个生物多样性报告率最高的国家之一，也是在热带地区最早努力收集有关土著真菌信息的国家之一。然而，真菌学数据仍然很少且不连续，尤其是关于土壤真菌。本研究旨在揭示上安第斯哥伦比亚农业生态系统中丰富的土壤真菌多样性。研究区域位于博亚卡省，该省具有显著的经济价值，部分用于自给农业。本研究共揭示了 150 多种已描述的物种，分属于 5 个门，其中子囊菌门为优势分类群。担子菌门和接合菌门也有很好的代表，分别以 Sebacina 和 Mortierella 属的物种为主，主要分布在半自然斑块（林地和草地）中。大部分物种都是哥伦比亚的首次记录。其中一些物种因其保护意义而特别有趣，例如在未改良草地斑块中占主导地位的 Geoglossum fallax。基于引导的聚类分析显示，果园和未开垦地区的物种分布不同，这可能是真菌群落对农业环境中土壤不同利用的一种反应。
