On the other hand, the tissue in the cone and in the portion of the central column beneath the gleba diminishes in proportion as the stipe enlarges, till at length in Ph. caninus (Fig. 153 j) it is only a thin white membrane ; in Ph. impudicus it remains of larger size underneath the gleba, forming a cup-shaped basal piece which supports the lower extremity of the stipe (Fig. 154) ; in the cone it stretches into a thin white membrane, as in the other species. The gleba, in which the formation of spores is completed or nearly completed during the expansion of the stipe, dilates in Ph. caninus into a thin conical cap covering the upper part of the stipe close beneath the extreme summit; in Ph. impudicus it diminishes less in thickness in proportion to the extension of its surface, and the hyphae of the trama even manifest an active growth by the expansion of their cells. No change in structure worth mentioning here occurs in the parts surrounding the stipe during the time that it is enlarging beyond an evident increase in the size of the hyphae. The cells of the parenchyma of the stipe itself continue thin-walled and. Fig. 153. Phallus cnninus.
