英文摘要：

[Objective] The objectives were to investigate and discover some rare and important fungi from the soil in China. [Methods] The classical morphological characters and molecular systematics were used for identification of strains obtained. [Results] A strain of the genus Scedosporium was isolated from the soil of pig manure. The main characters were as follows： on Czapek agar, floccose,gray white to light brown. Conidiophore was single or branched; Single conidiophores was usually reduced to the conidiogenous cells, which is terminal or lateral, hyaline to subhyaline, smooth,cylindrical or lightly inflated flask-shaped,（3.5-45.0） μm×（1.5-3.0） μm; Conidia single, terminal or lateral, smooth, ellipsoidal, obovoid or sub-cylindral,（4.3-14.0） μm×（2.5-5.5） μm. [Conclusion]Based on the morphological characters and molecular systematic, the strain was proposed as S.aurantiacum Gilgado, Cano, Gené Guarro, which is a new record species in China.
