Among them Eladia pachyphialis and Gliomastix pallescens are new species, while Acremoniula sarcinellae, Allescheriella crocea, Chrysosporium merdarium, Chrysosporium pannorum are new records to China. The main distinction between E. pachyphialis and its similar species E. saccula is that the phialide of the former is wider and the conidia are smaller than those of the latter. Gliomastix pallescens is characterized by having light colored, long and unbranched conidiophores by which it can be separated from its similar species, G. cerealis. Latin descriptions are given for the new species. Brief descriptions and illustrations of the new records are also provided based on Chinese isolates. The other 21 species being previously known from China in several genera are also listed. All specimens (dried cultures and slides) and living cultures studied have been deposited in the Herbarium of Shandong Agricultural University: Plant Pathology (HSAUP).展开更多
