Inhibiting Effect of 4 Toxic Mushroom Strains and Their Toxins on Cytospora Chrysosperma (Pers.) Fr.

Inhibiting effect of 4 toxic mushroom strains (Amanita virosa Lamb. ex. Secr., Amanita muscaria (L. ex. Fr.) Pers. ex. Hook., Lepiota clypeolaria (Bull. ex. Fr.) Quil., Lactarius vellereus (Fr.) Fr.) and their toxins on Cytospora chrysosperma (Pers.) Fr. Were studied. The results showed that the strains Amanita virosa and Lepiota clypeolaria inhibited growth of Cytospora chrysosperm. The strain Amanita virosa had a better inhibition effect. In antagonistic experiments, Cytospora chrysosperma promoted the growth of Amanita virosa. The eefect being the highest at 74 h, the inhibition  of Amanita virosa to Cytospora chrysosperma is also highest. Lactarius vellereus has growth-promoting effect on Cytospora chrysosperma. The percentage of growth inhibition of toxin crude extracts from 4 toxic mushroom strains on Cytospora chrysosperma mycelium are all 100 %, and the percentage of spore sprouting-inhibition is between 93.36 % - 97.29 %.
