DISCOVERY OF EARLY JURASSIC CONIDIUM OF A HYPHO-MYCETOUS FOSSIL FUNGUS

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.
