Concerning the Phalloids. 



MUTINUS CAXINUS (Plate 113). This is the original form 

 of Mutinus from Europe, but it occurs also in the Eastern States. 

 It differs from the two American forms (considered in our previous 

 paper) in having the gleba-bearing portion of the stem short, con- 

 tracted, and formed of smaller cells than the remainder of the stipe. 

 The gleba is a thick layer, definitely limited to this (upper) portion 

 of the stem, so that it appears at first view as though the plant had 

 a pileus as in the genus Phallus. Indeed, the old authors all included 

 it in the genus Phallus until Fries took it out in 1849. The stipe of 

 Mutinus caninus is slender, cylindrical, and nearly uniform in diameter. 

 Its color as I have noted it in France is red, as shown in the recent 

 picture of Monsieur Holland. Fischer described it as white (with 

 the upper portion red), and Hollos shows a plant with a white stipe. 

 It probably varies in this regard. Mutinus caninus has been well 

 illustrated in a number of old European works Sowerby, Flora 

 Danica (1259), and Curtis' London Flora. Also in the recent works 

 of Hollos and Rolland. 



GEOGRAPHICAL DISTRIBUTION EUROPE. It is the only species 

 of Mutinus that occurs in Europe, and is widely spread. In France it is not 

 uncommon. 



UNITED STATES. As far as known it is confined to the Eastern States, 

 and Professor Burt reported it in his paper as common in Vermont. I have 

 only received it from Professor James Fletcher, Ottawa, Canada. It is unknown. 

 I think, from other countries or from the tropics, though the Phalloids of most 

 foreign countries are very little known. 



HISTORY. Called by the old authors Phallus caninus, it was made the 

 I type of a new genus under the name Mutinus caninus by Fries. Sowerby called 

 it Phallus inodorous, and claimed it different from other Phalloids in the absence 

 of odor, a claim which I think has not been established. Mutinus Ravenelii 

 [and Mutinus brevis have been referred to the plant as synonyms, an error in my 

 opinion. 



CLATHRUS CANCELLATUS ~( Plates 92 and 112). We con- 

 sidered this plant in our previous article, but at that time had seen 

 no fresh specimens. W r e have received, through the kindness of 

 Monsieur Auguste Bernin, Monaco, fresh specimens from which we 

 are enabled to make a good photograph (Plate 112), the first photo- 

 graph, we believe, that has ever been published. Clathrus cancellatus
