Summary1.Media have been developed which produced characteristic pilei, normal as to size and markings, of the wood rotting fungi tested.2.The media used consisted of mixtures of corn-meal, starch, wood flour and malt liquid.3.The cultures grew rapidly on these media and soon developed typical sporophores.4.Media for growing sporophores of the larger fungi apparently must contain wood in some form in order to produce pilei of normal size.5.Wood flour is the best of the materials tested since it is immediately available for use by the growing fungi.6.Liquid media must be added to the growing cultures to produce normal pilei of fungi which have large sporophores.7.Pilei normal as to size and markings would not developinsidecontainers of ordinary size.8.The sporophores must extend beyond the mouth of the container into the outside air to produce characteristic pilei.9.The flask method described is especially adapted to fungi having stipitate sporophores.
