The community structure of macrofungi is influenced by multiple complex factors, including climate, soil, vegetation, and human activities, making it challenging to discern their individual contributions. To investigate the dynamic changes in macrofungal diversity in an Ancient Tree Park located in Northeast China and explore the factors influencing this change, we collected 1007 macrofungi specimens from different habitats within the park and identified 210 distinct fungal species using morphological characteristics and ITS sequencing. The species were classified into 2 phyla, 6 classes, 18 orders, 55 families, and 94 genera. We found macrofungal compositions among different forest types, with the mixed forest displaying the highest richness and diversity. Climatic factors, particularly rainfall and temperature, positively influenced macrofungal species richness and abundance. Additionally, by analyzing the soil fungal community structure and comparing aboveground macrofungi with soil fungi in this small-scale survey, we found that the soil fungal bank is not the main factor leading to changes in the macrofungal community structure, as compared to the influence of climate factors and forest types. Our findings provide valuable insights into the dynamic nature of macrofungal diversity in the Ancient Tree Park, highlighting the influence of climate and forest type.
大型真菌的群落结构受到多种复杂因素的影响，包括气候、土壤、植被和人类活动，因此很难辨别它们各自的作用。为了调查中国东北一个古树公园大型真菌多样性的动态变化，并探究影响这种变化的因素，我们从公园内不同栖息地采集了1007份大型真菌标本，并利用形态特征和ITS测序鉴定出210种不同的真菌物种。这些物种被分为2个门、6个纲、18个目、55个科和94个属。我们发现不同森林类型中的大型真菌组成不同，其中混交林的丰富度和多样性最高。气候因素，特别是降雨和温度，对大型真菌的物种丰富度和丰度有积极影响。此外，通过在这项小规模调查中分析土壤真菌群落结构，并将地上大型真菌与土壤真菌进行比较，我们发现与气候因素和森林类型的影响相比，土壤真菌库不是导致大型真菌群落结构变化的主要因素。我们的研究结果为古树公园大型真菌多样性的动态性质提供了有价值的见解，突出了气候和森林类型的影响。
