It may be assumed that there is a nucleus always present, though in the smaller forms it has been looked for in vain up to the present time. Where it has been observed, as in Dacryomyces, Calocera, Corticium calceum, and especially in "the basidia of Corticium amorphum (Fig. 30) which become imm. in length, it is a spherical weakly refringent body (perhaps the nucleolus), lying in about the centre of the cell. It is not to be seen in the early states of the basidium, and it disappears when the formation of sterigmata commences. More exact investigation into its behaviour in spore-formation has yet to be made. When the basidium has reached its full size, the sterigmata make their appearance on its rounded apex as narrow subulate sprouts, and when they have arrived at a certain length their extremity, which up to this time is finely pointed, swells into a vesicle which gradually acquires the form, size, and structure of the mature spore. As the spore advances to maturity the protoplasm of the basidium passes into the swollen extremities, .
