Since 2006, the research on the genus, Tuber, Lactarius, Cantharellus, AlbatrellusSuillus, and Tricholoma matsutak have been. 68 new species to science has been recognized. A numerous misidentified specimens and misapplied names have been studied in recent five years (Chen, 2007; Zheng, 2008; Chen JY, 2008; Wang, 2008; Yu, 2007; Tian, 2009; Shao, 2011). These results help us to get to appreciate species recognition for some renowned fungi in world, including Tuber indicum, T. himalayense, T. huidongense, T. matsudake, L. deliciosus, L. hatsudake, L. volemus and Albatrellus (Chen & Liu 2011; Deng et al. 2009, Yu et al. 2006, 2007; Zheng et al. 2008). Moreover, the results of researches also suggested that southwestern China is rich in temperate, endemic and tropical species. For example, the study of the genus Tuber suggests close connection between Southwestern China and the Mediterranean regions of Western Europe (Chen et al. 2011). The taxonomic work in Lactarius and Russula found representative tropical species in southwestern China (Wang & Verbeken 2006; Wang et al. 2009; Wang & Liu 2010). Diversity of Cantharellus and Albatrellus shows higher endemism of the species in southwestern China (Zheng & Liu, 2008; Tian et al., 2009; Shao et al., 2011) than other areas. All of our research reconfirmed the mycobiota of subalpine region in Hengduan mountains are of strong temperate affinity but has its own endemic members and mycoflora characters, such as T. indicum, T. zhongdianense, T. lijiang, Chinese “Lactarius laeticolor”, Cantharellus longipes, Suillus alpinus etc.

Our research on conservation and sustainable utilization of some endangered fungi, including T. indicum, Chinese “T. aestivum”, Tricholoma matsutake-complex and Lactarius volemus-complex havse succeeded to synthesize mycorrhizae between T. indicum and seven trees, Chinese “T. aestivum” with three trees and European black truffle (Tuber melanosprum) with two Chinese indigenous trees (Geng et al. 2009). The well developed technologies have being used for producing mycorrhizal seedlings in big batch for truffle plantation in limestone mountainous area, SW China. The technology was awarded State Invention Patents by the State Intellectual Property Bureau of China (Liu et al. 2011). In the semi-cultivation of milk cap (Lactarius volemus-complex), we helped the local farm communities to establish 80 demonstrating hectares in the local natural pines (Pinus kesiya var. langbianensis) secondary forest. The income has reached RMB 3.45 million Yuan for the Lancang county in each year. To better understand the ecological habit of these fungi, related basic research is also carried out, including mycorrhizal combinations of black truffles, ectomycorrhizal community of Pinus yunnanensis, rhizosphere micro-organisms community of black truffle and microorganism community of matsutake “shiro”. These work show some interesting results: T. indicum was found to grow with Yunnan aspen (Populus yunnanensis) (Deng 2009); Russuloid ectomycorrhizae were found to be the most dominant mycorrhizae on 1-2 years-old seedlings of Pinus yunnanensis (Xie et al. 2010); The endemic bacteria in Tuber ascomata could be significantly improve infection and formation of the mycorrhization of Tuber; micro-organisms community of matsutake shiro vary sharply difference between different localities. The findings are expected in turn to give direction to develop technology for conservation of well-known edible mycorrhizal fungi (EMMs).
