Abstract
Useful fragments such as hyphae are extracted from a raw sample containing water such a fungi attached to a plant. The sample is rapidly frozen and cut under vacuum largely and at random. Water contained in the sample is sublimated and the sample is coated with conductive material. While observing the sample by a scanning electron microscope, useful fragments are extracted from the sample by a micro-manipulator.
