Classification Studies On Nine Endophytes From Taxus Cuspidate

In this paper, the morphological characteristics of nine endophytes isolated from the barks , stalks , branches of Taxus cuspidate Sieb et Zucc. grown in Changbai nature reserve in Northeast China's Jilin province are studied through observation, description, shooting of culture-characteristics and microstructure.At the same time, the basic physiological experiments of four strains 1001 , 1003, 1014 and 1022 including varies of culture temperatures, pH, carbohydrate, nitrogenous nutrition, different concentration of medium and carbohydrate, some vitamins usually used in fungi culture, etc., are studied too.Finally, the level identification, classification of these nine endophytic fungi are studied through literature retrieving and comparison with related genus or type species, during which the characteristics of conidia and the result of physiological experiment are regarded as key words and as assist respectively. The ultimate result of these strains' classification are that one new species Coniothyrium macrospora Y.Xiang et J.X.Cui sp. nov.(1026); five new recorded-genus in China: Papularia sphaerosperma (Pers.ex Fr.) von U(?)bnel=Arthrinium sphaerosperma (Pers.ex Fr.)(1005), Gilmaniella humicola Brron(1022), Oedocephalum glomerulosum (Rulliard) Sacc. (1016), Trichosporonoides oedocephalis Raskins & Spencer(1023), Ambrosiella brunnea (Verrall) Batra(1008); and three known genus in our country: Eurotium amstelodomi Mgngin(1001); Eurotium repens de Bary(1003) and Botrytis sp(1014) are found. The identification of these strains gives the theory of the further research of endophytic fungi. And the discovery of those new species make up the margin of our country in the genus above-mentioned.
