FORMATION OF MICROENDOSPORES IN CERATOCYSTIS ULMI (BUISM.) C. MOREAU

摘要

A morphological study of several isolates ofCeratocystis ulmihas revealed that spores and hyphae of this fungus contain minute cytoplasmic particles that behave like spores (microendospores). The different stages of development of these microendospores are described and some implications of the findings are briefly discussed.
