The understanding of distribution and the evolutionary scenario is crucial for the utilization and conservation of biological resources; nevertheless, such explorations rarely focus on macrofungi. The current study selects a macrofungal genus, and explores its spatiotemporal pattern in China. A total of 117 available occurrence records of in China were summarized for the current analyses. Ensemble modeling supports the highly suitable habitat of concentrated in southern, especially southeastern, China, where the ancestor of originated 77.74 million years ago and then dispersed to other parts of China. Benefitting from the available suitable habitats, rapidly diversified after its divergence in Southeast China. Then, the net diversification rate slowed down when the rapidly diversifying species filled available niches in Southeast China and the dispersed species in other parts of China inhabited the less suitable and unsuitable habitats. During adaptive evolution, precipitation, temperature and the host plant are the major environmental variables that shape the spatiotemporal pattern of . In conclusion, the current study reveals the adaptive evolutionary scenario of and provides the first exploration of the spatiotemporal pattern of macrofungi.
对分布情况和进化历程的了解对于生物资源的利用和保护至关重要；然而，此类探索很少关注大型真菌。当前的研究选取了一个大型真菌属，并探究其在中国的时空分布模式。本分析共汇总了中国境内该属的117条现有分布记录。集成建模表明，该属高度适宜的栖息地集中在中国南方，尤其是东南部，其祖先于7774万年前起源于此处，随后扩散至中国其他地区。得益于现有的适宜栖息地，该属在中国东南部分化后迅速多样化。然后，当快速分化的物种占据了中国东南部的可用生态位，而扩散至中国其他地区的物种栖息在不太适宜和不适宜的栖息地时，净多样化速率放缓。在适应性进化过程中，降水、温度和寄主植物是塑造该属时空分布模式的主要环境变量。总之，当前的研究揭示了该属的适应性进化历程，并首次探索了大型真菌的时空分布模式。
