The young spore, like the cells of the mycelium from which it is derived, contains two nuclei (fig. 1^20). These undergo fusion, so that the mature spore is uninucleate (fig. 152(5). The pairing of the nuclei, which begins with the association of the basidiospores (or their conidia), is thus completed in the brand-spore. The minute
