| Abstract: | Seasonal distribution of nematode-trapping fungi in orange rhizome soil of Bingchuan County was investigated from June 2007 to March 2008.Four hundred soil samples were collected from orange rhizome.23 species were isolated partially,belonging to 3 genera.Among them,D.daliensis was here described as new species,D.Heptameres and D.spermatophaga were new records to China.A.oligospora,A.musiformis and A.dactyloides were the predominant species,and M.ellipsosporum,M.thaumasium,and M.eudermatum were frequently encountered.The fungi were abundant in late spring and early summer and slightly in autumn and winter. |
