the ground, and sometimes it develops in the greatest abundance on 

 old piles of sawdust. The species is only known from the United 

 States and Canada. 



PHALLUS RUGULOSUS (Fig. 9). Pileus, thimble-shaped, 

 almost even or slightly rugulose, with a small, globose, apiculate col- 

 lar. Color, dark. Veil, none. Stem, pale reddish. This species was 

 described from alcoholic material, and is known only from Japan, 

 where it is reported to be common. I have seen a drawing from 

 Professor Kusano. As I understand it, the substance of the pileus is 

 not red, otherwise the plant seems close to Phallus rubicundus. I 

 should not be at all surprised if it develops that it is a slender form 

 (gracilis) when the color of the pileus substance is known. 



PHALLUS GLUTINOLENS (Fig. 10). This is a unique 

 species of Phallus, known only from Brazil. It has white stipe and 

 no evident veil. The pileus is smooth and differs from all other species 

 in the globose shape. It has only been observed by its original author, 

 who gives us a good photograph of it. 



PHALLUS SUBTILIS (Fig. n). This Brazilian species has 

 only been illustrated by a sectional drawing. A photograph would 

 not show any marked difference from any other small Phallus. It 

 was erected into a separate genus because the pileus has no apical 

 collar, and a section shows it to be formed of radiate plates. It is also 

 somewhat gelatinous in its nature. It is only known from Brazil and 

 from the work of the original author. 



SECTION 2. VEIL EVIDENT, USUALLY STRONGLY DEVELOPED. 

 PILEUS STRONGLY RETICULATE. 



PHALLUS INDUSIATUS (Fig. 12). Pileus broadly campan- 

 ulate, strongly reticulate. Veil strongly developed, of small, slender 

 threads and large meshes. Color of stipe and veil white. This is 

 the most common phalloid of all tropical countries and is found in 

 quantities in all of the museums. We have noted specimens from 

 Australia, India, Andaman Island, Java, Ceylon, East Africa, Mau- 

 ritius, Mexico, Brazil, British Guiana, French Guiana, South Africa, 

 Surinam, New Caledonia, Cuba, Tonkin, Philippines, Borneo, Ja- 

 maica. We have received it from a number of correspondents and 

 have collected it (common) in Samoa. 



Forms. 



Phallus indusiatus varies in the tropics, chiefly in the shape of the pileus 

 and the veils. Also in color, I think, and I suspect that in time it will not 

 be found practicable to keep distinct Phallus callichrous and Phallus multicolor 

 as other than color forms. Usually the veil is flaccid, but at other times more 

 rigid. Sometimes it is united above into a distinct membrane. These forms 

 seem to have a geographical significance, but so little is known that at present 

 it is not possible to designate the distribution of the various forms. In Samoa, 

 where I have observed it common, it never takes anything but the type form.
