The patterns of sclerotial development in Botrytis cinerea were studied under controlled enviromental conditions capable of inducing sclerotial formation. Two types of sclerotial development were distinguished. Terminal type of sclerotia was induced by mounting a cover-glass on the tips of vegetative hyphae for a definite period of time. On the other hand, lateral type of sclerotia was induced in a narrow region of the mycelia produced at the beginning of high-temperature treatment by exposing to a temporary high-temperature. Thus, in Botrytis cinerea which has been previously grouped into a former of terminal type of sclerotia, there also exists the lateral type of sclerotial development.
