outermost part of /, the pileus of the receptacle arises, as in P. tenuis, 

 but with less cooperation of the hyphae radiating from the tramal plates. 

 The layer A and the greater part of / develop no further; they remain as 

 simple hyphal tissue and are torn and destroyed by the unfolding of the 

 receptacle. In the mature egg, differentiation is similar to that of P. 

 tenuis but the vestiges of the tissue A (A and the inner part of I) occupy 

 much more space than in the latter. The part which interests us here, 

 corresponding to the top in Fig. 336, 1, is given in Fig. 336, 2 for a 

 somewhat older stage. The small projection V suggests the spot where 

 in Fig. 336, 1 the inner layer / was attached to the stipe wall.

-Phallus impudicus. Median section of top of young fructification. (X 18; 

 after E. Fischer, 1891, 1893.) 



This species is popularly called stink horn. Its eggs are eaten at 

 times in Europe. Earlier both these and the ripe fructifications were 

 used as drugs in the preparation of salves and powders for rheumatism 

 and pestilence. 



In the Polynesian Echinophallus Lauterbachii (Fig. 335, 1), which is 

 known only in the young stages, the zone I increases markedly at the 

 expense of zone H (E. Fischer, 1900) which is very narrow and much 

 curved outwards. In contrast to Phallus and the other Phallaceae here 

 discussed, it forms no continuous layer but is discontinuous like a lattice. 

 In longitudinal section (Fig. 335, 1) it shows only as short pieces, sepa- 

 rated from one another and much enfolded in the gleba. 



At approximately two-thirds of its height, there arises a campanulate 

 appendage /, 2 to 3 mm. broad, consisting of a simple layer of closed cham-
