COMPARATIVE MORPHOLOGY OF FUNGI 



a fructification whose gleba has already flowed away is given in Fig. 334; 

 in nature, it is isabelline. 



In Phallus impudicus (E. Fischer, 1891, 1893; Bambeke, 1910), the 

 development proceeds in such a manner that the layer A undergoes a 

 stronger development and in the stage corresponding to that shown in 

 Mutinus (Fig. 332, 4) and P. tenuis it is differentiated into three layers

 fication. Phallus tenuis. 2. Median section of mature egg. Dictyophora indusiata. 3.

(Fig. 336, 1). The outermost zone H, directly bordering on the tramal 

 pads, assumes a somewhat different character and is more refractive. 

 The middle, thick zone I is campanulate and parallel to H but, instead of 

 reaching the columella, passes over laterally into knotted cover St.w. 

 The inner zone A has a structure corresponding to that of the original 

 intermediate tissue with hyphae more or less definitely radiating from 

 the stipe axis toward the periphery. From the layer H and from the
