通过对研究鉴定出的中国白鬼伞族真菌的地理分布进行整理和统计分析，初步得出了我国白鬼伞族真菌的地理分布特点。根据现有资料，白鬼伞族真菌在中国的分布范围较为广泛，西南地区和华南-东南地区是中国白鬼伞族真菌的物种多样性中心。对同是热带分布的长柄大环柄菇、球盖青褶伞及绿褶托菇的世界分布图进行了绘制，并对三者的分布式样进行了分析及探讨。; Based on extensive field investigation and materials from main mycological herbaria from China, including GDGM, HKAS, HMAS, HMJAU, MHSU, as well as putative collections deposited in abroad herbaria such as BPI and FH, taxonomy and molecular phylogeny of the tribe Leucocoprineae from China were studied. Sericeomyces has been recognized as a separate genus and the infrageneric system within the genus Macrolepiota was improved by introducing a new section, M. sect. Volvatae. Species cited in literature but turned out to be misidentified were discussed and corrected. Based on sequence data from the nuclear ribosomal large subunit gene (nLSU), the internal transcribed spacer region of the nuclear ribosomal array (ITS), and the mitochondrial ribosomal small subunit gene (mtSSU), phylogenetic trees of Leucocoprineae were reconstructed and systematic positions of genera within the tribe and relationships among the genera were discussed. Furthermore, distributions of Leucocopeineae within China were supplemented and discussed with an emphasis on tropical distributed exemplars. Southwestern China and South-Southeastern China are two species diversity centers as suggested by the current data. The main results of the dissertation were summarized as follows:
Specimens of putative Leucocoprineae from China collected by the author and by colleagues were examined. As a result, thirty-nine species were identified which belong to six genera of this tribe, including five species within Chlorophyllum, one species within Clarkeinda, fourteen species within Leucoagaricus, six species within Leucocoprinus, six species within Macrolepiota, and seven species within Sericeomyces. All identified species were described and illustrated in detail, and differences between similar species are provided and discussed. A key to the genera of the Leucocoprineae and keys to the species belong to the six studied genera in the tribe were provided.
Among the thirty-nine identified species, five are new to science and seven are new to China. The new taxa are Chl. sphaerosporum Z. W. Ge & Zhu L. Yang, M. orientiexcoriata Z. W. Ge & Zhu L. Yang, S. subcrystallifer Z. W. Ge & Zhu L. Yang, S. subpurpureolilacinus Z. W. Ge & Zhu L. Yang, and S. truncatus Z. W. Ge & Zhu L. Yang; the new records to China are Chl. globosum (Mossebo) Vellinga, Chl. hortense (Murrill) Vellinga, La. holospilotus (Berk & Broome) Bon, La. lacrymans (T.K.A. Kumar & Manim.) Z.W. Ge & Zhu L. Yang, La. nympharum (Kalchbr.) Bon, La. serenus (Fr.) Bon & Boiffard and Lc. cretaceus (Bull.: Fr.) Locq. Besides, three new combinations, namely La. lacrymans (T.K.A. Kumar & Manim.) Z. W. Ge & Zhu L. Yang, S. brunneocanus (J. F. Liang & Zhu L. Yang) Z. W. Ge & Zhu. L. Yang and S. rubrotinctus (Peck) Z. W. Ge & Zhu L. Yang, are proposed.
With regard to the infrageneric classification of Macrolepiota, section Macrolepiota and section Macrosporae were accepted, and a new section, M. section Volvatae Z. W. Ge & Zhu L. Yang, is proposed to accommodate the volvatae Macrolepiota species based on macro- and micro-morphological characters.
Morphological characters support the recognition of Sericeomyces as a separate genus that differs from Leucoagaricus. The structure of pileal surface of Sericeomyces is an epicutis composed by undifferentiated repent hyphae, while those of Leucoagaricus, a heterogeneous group, are much more diverse; basidiospores of Sericeomyces representatives are constantly without a germ pore and amygdaliform-shaped with an apical papilla, while some species of the Leucoagaricus bear a germ pore and the shapes of the spores are also more diverse. Besides the species with scales typically without pigments, species previously placed in Leucoagaricus but with an epicutis pileal structure and amygdaliform-shaped spores with an apical papilla, such as La. rubrotinctus, should be transferred to Sericeomyces in spite of their colored pileal surface.
Current classifications of the Leucocoprineae were evaluated by means of molecular phylogeny. Parsimony and Bayesian analyses were performed to reconstruct the phylogenetic tree of Leucocoprineae based on sequence data from ITS, LSU, and mtSSU. Results of the analyses show that Leucocoprineae is not monophyletic, with Agaricus, the type genus of tribe Agariceae, and its allies derived from the Leucocoprineae clade and formed the sister clade to Chlorophyllum. With regard to the monophyly of genera circumscribed by morphology within the Leucocoprineae, Sericeomyces recognized as a separate genus got strong statistic supports from both parsimony and Bayesian analyses; revised genera Chlorophyllum and Macrolepiota formed monophyletic group of their own respectively, while genera Leucoagaricus and Leucocoprinus are shown to be artificial, with species of either genus shifted from one to another. Phylogenetic study of Macrolepiota based on ITS data support the recognition of three sections within it. The new section, M. section Volvatae, proposed to contain the volvatae species of Macrolepiota received strong supports from both parsimony and Bayesian analyses.
The geographic distribution of Leucocoprineae within China were summarized and analyzed. Leucocoprineae has a wide distribution in China. Southwestern China and South-Southeastern China are two species diversity centers as suggested by the current data. Distribution map of C. trhacodes, Chl. globosum, as well as M. dolichaula was protracted, and their biogeographic patterns were discussed.|
