Abstract: The influence of various temperature and media on the mycelial growth of the Elfvingia applanata (E-1～3),Fomitopsis castaneus(N-1)and Lloydella bicolor(L-1)were studied. The result shows,the optimum temperatures for the mycelia growth of E-1～3 and N-1 is 32℃,L-137℃;the maximum temperature for E-1～3 and N-1 37℃,L-1 42℃;minni-mum temperature for E-1～2 and L-1 10℃,for E-3 and N-1 17℃,inhabited temperatures for E-1～3 and N-1 42℃,L-1 47℃,the lethal temperature for E-1～36 hrs at 50℃,N-1 8 hrs at 47℃,L-1 5 hrs at 54℃. At the same temperature and on the same media,the mycelia growth of 3 isolates of E. applanata is different.
