thick threads, which in alcoholic specimens contract and form almost 

 a membrane. This is a common plant in the United States and is so 

 close to the tropical species it may well be considered a temperate 

 region form of it. However, it differs in the nature of the veil and 

 the usual shape of the pileus, and I am convinced that it is as dis- 

 tinct as species generally are. The veil (which is torn in our figure) 

 is a conspicuous feature of the plant. 



Forms. 



We would be disposed to consider related plants with a similar veil as 

 forms of this species. 



PHALLUS SUBUCULATUS, of Algeria, which was inaccurately figured, 

 is, we think, a form of it. 



PHALLUS MAURITIANUS (Fig. 17). This form, which we have re- 

 ceived in alcohol from Chas. O'Connor, of Mauritius, we feel is worthy of a 

 separate designation as a form. It differs from the typical plant in the nature 

 of the reticulations of the pileus, and is better shown in our photograph than 

 we can tell it. 



Note.- -We formerly included in this section, under the name Phallus irpicinus, the 

 only known phalloid with a well developed veil and rugulose pileus. It was proposed as a 

 new genus (or a new section) Clautriavia, on account of having the pileus minutely con- 

 volute. We were not disposed to consider that of generic value, until recently when we saw 

 at Berlin a New Guinea species with such a strongly convolute pileus, and such a marked 

 character that we now feel that the genus Clautriavia should be maintained. Compare Clau- 

 triavia merulina on the next page. 



IMPERFECTLY KNOWN SPECIES OF THE GENUS PHALLUS. 



Many phalloids are known (?) only from old cuts based mostly on dried 

 specimens and, in some instances, fertile imaginations. Naturally they are 

 of not much importance for no one ever finds them again, but there is no 

 way of getting rid of them. The genus Phallus has been especially favored (?) 

 in this regard. We give a short synopsis of them here and have relegated the 

 (alleged) pictures to an appendix. 



PHALLUS DISCOLOR (Fig. 95). From Australia, if correctly illus- 

 trated (with an emphasis on the "if"), is an intermediate plant connecting 

 the genera Phallus and Mutinus. It was alleged to have the pileus adnate 

 at the base to the top of the stem. 



PHALLUS CALYPTRATUS (Fig. 96). From Australia. Appears to 

 be based chiefly on an accidental mass of gleba dried on top of the pileus. 



PHALLUS RETUSUS. Originally exploited as a new genus, it is re- 

 ported by Professor Fischer (who has seen the "type") as an obese form of 

 auran'ciacus. The figure has no resemblance to aurantiacus, but it does not 

 follow that the plant has none. It was from Australia. 



PHALLUS CAMPANULATUS (Fig. 98). Known only from the figure 

 (Uruguay). The little cup at the base is not the volva, but the "inner" yolva. 

 It seems to have an even pileus and be close to Ravenelii, though nothing is 

 known as to its veil. No specimen exists. 



PHALLUS CELEB1CUS (Fig. 99). Said to grow in the Celebes and 

 to have a whitish pileus and a yellow stem. It appears from the published 

 account to be very close to Phallus rubicundus. 



PHALLUS CANARIENSIS (Fig. 100). If the figure is correct it is a 

 peculiar little species with a slender stipe and large, rugulose pileus. Both
