. Comparative morphology of Fungi. Fungi. GASTEROM YCETES 517 in the course of development and consequently in the stage of Fig. 336, 1 are recognizable as such only in the apical end of the egg. This tissue I reaches its greatest development in Dictyophora; here it develops to a beautiful structure (E. Fischer, 1887, 1890, 1891, 1900, 1910; Moeller, 1895; Burt, 1897; Atkinson, 1911). It is chambered, like the receptacle, and follows the inner side of the pileus from the top to the base of the egg (Fig. 335, 2). When the stipe elongates at the unfolding of the fructification, the layer I, together with the pileus and the gleba lying on it, is raised. Then the folded chamber walls elongate in this layer, as did the receptacle stipe (Fig. 337, 2), and the layer/ expands like a crinoline toward the bottom and unfolds to a latticed indusium. This indusium is only an appendage of the receptacle stipe and, in con- trast to the pileus, is not directly connected with the gleba. It is formed when the gleba is just beginning to form and its ends are still far removed from the stipe. Its significance is not yet Fig. 338.—Section of hypothetical transitional form between Aseroe and the Phallaceae. 2. Diagram of young fructification of Phallus. Letters as in Fig. 332. (After E. Fischer, 1910.) A majority of the Clathraceae and Phallaceae are entomochorous and by their strong odors attract attention from a distance. The fructifications generally unfold at night and at dawn, the gleba has mostly dropped off. As Lohwag (1924) has demonstrated, in this grouping the Phallaceae would be regarded as derivatives of the Clathraceae. In both families the organization is fundamentally the same, only in the former the tramal plates grow centripetally, in the latter centrifugally. If one imagines that the development which leads from Protubera, Clathrella, Anthurus through Aseroe arachnoidea to Aseroe rubra, continues, and that the widening of the central strand S (Fig. 330, 7), ap
