Abstract

Tiankeng acts as a refugium for biodiversity amid a changing global climate, and a previous study has shown that some ancient () and unique plants (cool-adapted plants) are present in Tiankeng. However, there are few reports on Ascomycota from the Tiankeng karst region. In this research, the species diversity of -like fungi in Monkey-Ear Tiankeng was investigated. Seven species in the genera , , , and were identified based on internal transcribed spacer sequences and morphological characteristics. Eight new species in the genera , , and were established and described according to a multilocus phylogenetic analysis and morphological characteristics. Our results revealed that -like fungi were abundant in Monkey-Ear Tiankeng, providing new insights into the diversity of Ascomycota in this special eco-environment. Karst Tiankeng has a special eco-environment and acts as a refugium for biodiversity. However, there are few reports on Ascomycota from the Tiankeng karst region. In this research, seven known species and eight new species in the genera , , , and were reported. The results showed that -like fungi are abundant in Monkey-Ear Tiankeng. Interestingly, the month of the sampling was November, which is not an active period of growth and reproduction for -like fungi. These results revealed that unconventional time sampling should not be ignored, especially for a special eco-environment, and provided new insights into the diversity of Ascomycota in this special eco-environment.

摘要

天坑作为全球气候变化中的生物多样性庇护所，先前的研究表明，天坑中存在一些古老的（）和独特的植物（冷适应植物）。然而，关于天坑喀斯特地区子囊菌的报道很少。在这项研究中，调查了猴耳天坑中类似真菌的物种多样性。根据内部转录间隔区序列和形态特征，确定了 、 、 、 属中的 7 个种。根据多基因系统发育分析和形态特征，建立并描述了 、 、 和 属中的 8 个新种。我们的结果表明，猴耳天坑中存在丰富的类似真菌，为该特殊生态环境中子囊菌的多样性提供了新的见解。

喀斯特天坑具有特殊的生态环境，是生物多样性的庇护所。然而，关于天坑喀斯特地区子囊菌的报道很少。在这项研究中，报告了 、 、 、 属中的 7 个已知种和 8 个新种。结果表明，猴耳天坑中存在丰富的类似真菌。有趣的是，采样月份是 11 月，这不是类似真菌生长和繁殖的活跃期。这些结果表明，非常规时间采样不应被忽视，尤其是对于特殊的生态环境，为该特殊生态环境中子囊菌的多样性提供了新的见解。
