Scedosporium aurantiacum, a potential pathogenic mitosporic fungus

Abstract:

[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.
