THE PHALLOIDS OF JAPAN. 



In the beginning we wish to acknowledge our indebtedness to 

 the following gentlemen for notes, drawings and photographs from 

 which this article is written. 



Professor Kusano for seven colored drawings and specimens in 

 alcohol, also (Fig. 242) a photograph which we reproduce of Later- 

 nea bicolumnata. 



Professor M. Gono, for notes and two colored drawings. 



Professor A. Yasuda, for notes and published plates of two 

 species.

In the following list of the seven phalloids all that are cer- 

 tainly known to us to grow in Japan we give the Latin name and 

 follow it by the Japanese name. The latter we have taken from 

 Matsumura's list or from the notes of our correspondents. In some 

 cases we suspect these Japanese names have been switched. Thus, 

 it is strange that Phallus rugulosus should have two common names, 

 and Phallus impudicus, a more common and larger species, should 

 have none. We should consider it a favor if our Japanese readers 

 will advjse us of any errors as to these common names or of other 

 mistakes that may occur in this account. 



PHALLUS INDUSIATUS. Komuso-take; Kinugasa-take; 

 Sikedake. Pileus broadly cainpanulate, rather faintly reticulate, 

 furnished with a permanent apical collar, color dark; veil (indusium) 

 protruding from under the pileus and surrounding the stem, con- 

 sisting of a fine network, color white; stipe white. 



History. Phallus indusiatus is a frequent plant in many warm countries' 

 It can be known at once among the Japanese species by its strongly developed 

 veil. It is recorded in Matsumura's list as Dictyophora phalloidea from 

 Tokio, but the authority for it is not stated. I have a colored figure of it from 

 Professor Gono of lyo. The typical form of Phallus indusiatus usually occurs 

 in warm countries, and Professor Gono's figure is typical of the type form. 

 In America, in the more temperate regions, it takes a slightly different form, 

 called Phallus duplicatus. As we have seen no figure of the form from Tokio, 

 we can not say as to which it should be referred. 



PHALLUS IMPUDICUS. Pileus rather narrowly campanu- 

 late, strongly reticulate with a strong apical collar, color dark; veil 

 none or only rudimentary; stipe white. 



History. Phallus impudicus is the original phalloid known from Europe 

 where it is very common. In the United States it is much more rare, and takes 

 with us only a pink form known as Phallus imperialis. It occurs in Matsumura's
