Taxonomy And Molecular Phylogeny Of Several Genera Of Xylariaceae From China

Eight genera of Xylariaceous fungi include 89 species in total in this studies. There was 1 new record genus in China and 1 new record genus in Chinese mainland,10 new species,26 new record in China and 32 new record in Chinese mainland in this studies.

Rogers & H.M. Hsieh were firstly recorded in Chinese mainland in subgenus Hypoxylon.There were two species of Nemania were firstly reported in China as new record. They are Nemania aenea (Nitschke) Pouzar var. aenea and Nemania serpens (Pers.:Fr.) S. F. Gray var. hydnicola (Schwein.) Y.-M. Ju & J. D. Rogers。There was 1 species of Rosellina are reported, it is Rosellinia corticium (Schwein.) Sacc., is new record of Chinese mainland.There were 45 species of Xylaria were discribed. Nine species were discribed as new species. They were Xylaria ficicola H.-X. Ma, Lar.N. Vassiljeva & Yu Li, Xylaria meliacola H.-X. Ma, Lar.N. Vassiljeva & Yu Li, Xylaria dolichatrichus H.-X.

Twelve species of Xylaria arbuscula Sacc., Xylaria areolata (Berk. & M.A. Curtis) Y.M. Ju & J.D. Rogers, Xylaria badia Pat., Xylaria bambusicola Y.M. Ju & J.D. Rogers, Xylaria brunneovinosa Y.M. Ju & H.M. Hsieh, Xylaria cubensis (Mont.) Fr., Xylaria curta Fr., Xylaria escharoidea (Berk,) Fr, Xylaria laevis C.GLloyd, Xylaria multiplex (Kunze) Fr., Xylaria papulis C.G.Lloyd, Xylaria schweinitzii Berk. & Curt, were firstly recorded in Chinese mainland.Advanced research and discussed the result of morphology by molecular biology methods, and got the phylogenic evolutionary relationship inter the Xylaria genus or among the other genus. The results of constructed the phylogenetic tree base on the ITS sequences of the genus Creosphaeria, Daldinia, Hypoxylon, Kretzschmaria, Nemania, Rosellina and Xylaria showed that the genus framework of molecular phylogenic relationship inter this genus were clear. They had almost the same results through analyzing the relationships of the genus base on the three analysis methods.We accepted most of the genera of the familiy in two large groups, the Hypoxyloideae, characterized by the production of stromatal pigments of KOH and Nodulisporrium-like anamorphs (e.g. Hypoxylon, Biscogniauxia, Camillea, Daldinia), and Xylarioideae, which do not yield stromatal pigments in KOHand produce Geniculosporium-like anamorphs (e.g. Xylaria, Rosellinia, Nemania). The view was supported by molecular biology methods and got the phylogenic tree based on ITS sequences.
