Abstract
An apparatus is described by which fungous spores can be uniformly distributed on microscope slides. A procedure is outlined whereby Petri dishes can be converted into airtight humidity chambers, the humidity of which can be readily checked. It was found that above 94% relative humidity maximum germination among Beauveria bassiana spores occurs at 28 °C.
