After the fusion of the dikaryon in the basidium of Coprinus sterquilinus the fusion nucleus undergoes considerable enlargement. Associated with the nucleus there is a large "nebenkern." The latter body consists of a hyaline matrix containing a variable number of saucer shaped chromophilic platelets. As the fusion nucleus advances into the meiotic prophase, the nebenkern expands, the platelets scatter in an irregular manner into the cytoplasm, and apparently increase in number. The material of the nebenkern moves down toward the base of the basidium, and does not seem to be intimately associated with the subsequent meiotic processes of the nucleus.
