(1) Both chlamydospore and conidium germinated best in the peptone and beef extract solution.

(2) It is presumed that chlamydospore may be the major primary infection source of rice false smut and begin to infect the panicles of rice before or after florescence.

(3) Quantity of chlamydospore of Volvariella volvacea which cultivated in different culture medium with various C/N ratios in this paper was investigated.

(4) The mycelium and the chlamydospore were not tolerant of drought.

(5) The fruiting test found that those who can fruiting single spore strains, the dense gas Health mycelium developed, fast growing and will be a large number of chlamydospore.
