基金Authors are appreciative to Dr.John Haines for allowing us access to type specimen of Stachybotrys elongata.The authors are also very grateful to Drs.Walter Gams,Rafael F.Castañeda Ruíz,Hongxin Mao,Weidong Wu,and Ariunaa Jalsrai for their assistance in finding literatures,especially the ones in Japan,Russia,and Ukraine.Without their assistance some references would not be available to us.This project was supported by the International Scientific Cooperated Project of Guizhou Province(No[2013]7004).
