摘　　要：本文阐述了陕西焦坪矿区66号钻孔下侏罗统富县组“花斑泥岩”中发现的丝孢菌类分生孢子化石,并且鉴定出一个新属、一个新种。继而采用能谱仪及波谱仪对其成分作了定性分析,讨论了它与“花斑泥岩” 沉积环境之间的关系。作者认为丝孢菌类出现的时代应从白垩纪提前到早侏罗世。This paper reports on the conidial structure of a hyphomycetous fossil fungus in the graniphyric mudstone of Fuxian formation of Lower Jurassic from the drill hole No. 66 in Jiaopin mine area of Shaanxi province. The fossil was identified as a new species of a new genus, and its morphology and composition had been studied qualitativly with the scanning electron microscopy. According to the morphology and its relationship with the depositional environment of the graniphyric mudstone, it is considered that the age of the fossil may be identified occur as early as Early Jurassic period.
