Abstract:

The resources of macrofungi in the Luoxiao Mountains have been investigated for 5 years, and more than 5,100 specimens were collected. A total of 672 species of macrofungi, belonging to 20 orders, 72 families and 218 genera, have been identified based on morphological and molecular analyses. Among them, there were 115 species in the Mufu Mountains, 168 species in the Jiuling Mountains, 77 species in the Wugong Mountains, 220 species in the Wanyang Mountains and 193 species in the Zhuguang Mountains. There were 37 newly recorded genera and 514 newly recorded species in the Luoxiao Mountains. The species composition of macrofungi in the Luoxiao Mountains showed that there were 18 dominant families with more than 10 species, accounting for 73.36% of the total species, including Polyporaceae, Agaricaceae, Entolomataceae, and so on. There were 34 dominant genera with more than 5 species, accounting for 55.36% of the total species, such as Entoloma, Amanita, Marasmius, and so on. There were 2 genera and 46 species endemic to China in this mountain range. The assessment of utilization value of the macrofungi showed that there were133 edible species, 136 medicinal species and 87 poisonous species in the Luoxiao Mountains, indicating the resources have good application prospects. This study provides important scientific basis for the protection, utilization and management of macrofungal resources in this area.
