When conidia of Cochliobolus miyabeanus were held for 5 hours at 28℃ under increasing hydrostatic pressures (100-500 kg/cm^2), the length of germ tubes decreased with increasing pressure, and their forms changed from filamentous to elliptical to spherical. In control germ tubes the nuclei were scattered in a cell, whereas at 200 kg/cm^2 the nuclei were clustered. No germination occurred at 600 kg/cm^2 and above. When conidia which were obtained by compression at 100-700 kg/cm^2 as above were kept under suitable condition for germination on slide, ordinary germ tubes elongated vigorously from abnormal germ tubes and from ungerminated conidia. Percentage of abnormal branching in these germ tubes increased with increasing pressure.
