the best picture possible of each species, and in many cases the copies of the 

 original illustration from which the description was drawn. With these facts 

 before him, the reader can learn just as much about the phalloid as the author 

 who named it and wrote the "description." 



CLASSIFICATION. 



There are relatively few genera of phalloids, and they are classed 

 by their general form, so that the classification is a very simple mat- 

 ter and will be readily understood by the following table and the 

 illustrations. As a matter of convenience we divide them into five 

 groups : 



ist, The simple stem section. Gleba borne directly on the upper portion 

 of a simple stem, or on a pileus borne on top of a simple stem. 



Gleba borne on the outer surface of a special pileus. 



Pileus even, rugose, or reticulate Phallus 



Pileus surface strongly convolute Clautriavia 



Pileus of a lamellate structure, the gleba covering the plates. . . . Itajahya 



Gleba borne directly on the upper portion of the stem. No special pileus. 



Smooth, even Mutinus 



Rugose, papillate or uneven Jansia 



Gleba covering a rudimentary network Floccomutinus 



2d, The lobed section. Gleba spread over or on the inner surface of free 

 arms or lobes at the apex of the stem. 



Arms free at the apex of a columnar stem Lysurus 



Stipe, a flaring tube, the limb lobed Anthurus 



Stipe bearing a disk-like expansion, the limb divided into lobes or 



segments Aseroe 



3d, The columnar section. Receptacle consisting of simple, vertical col- 

 umns, united at the top and bearing the gleba on the inner sides. 



Sessile Laternea 



Stalked Pseudocolus 



4th, The clathrate section. Receptacle in the form of a clathrate or lat- 

 ticed structure. 



Sessile, simple Clathrus 



Stalked, receptacle a simple net. 



Borne on a simple stem Simblum 



Borne on columns that are united into a hollow tube at the base Colus 



Stalked, the net-work having knob-like projections Kalchbrennera 



5th, Anomalous genus, without volva Phallogaster 



THE GENUS PHALLUS. 



This is the original genus of Europe and from whence the name 

 of the order is derived. The genus is very simply characterized by 

 having a pileus, borne on the top of a simple stem. All species of 

 the genus are very much alike as to shape, but differ in color, in 

 size, in smoothness or roughness of the pileus, and in various de- 

 velopments of a veil. This veil, which is only known as rudimentary 

 in the related genus Mutinus, varies much in different species of 

 Phallus, and even in the same species in degrees of development. 

 Some species have only a rudimentary veil, others a distinct but very
