(The original of Miss Ellis's drawing, torn. cit. t. xiv. f. 16, is in the B.M. 

 collection. It is made up from the specimen and the accompanying sketches, 

 and probably poorly represents the former when gathered, either in shape or 

 colour.) The veil is dependent, but judging from the type-specimen there 

 is no reason against considering it, from a morphological point of view, as a 

 badly- preserved D. phalloidea. Penzig (Ann. Jard. Bot. Buitenzorg, xvi. 

 154 (1899)) records D. multicolor from Java, where he found it not very 

 common. He regards it as easily distinguishable from D. phalloidea by its 

 orange-coloured indusium. The volva is dark brown, the stipe pale yellow 

 (cream), and the pileus dark yellow after the dark olive-green gleba has 

 been washed away ; the mycelial strands are reddish. He regards this 

 species as, on the average, smaller than D. phalloidea. 



The specimens of the present collection are doubtless D. multicolor as 

 interpreted by Penzig. 1 



Another species which apparently differs only in colour from D. phalloidea 

 is D. callichroa Moll., based upon a single collection (Moller, torn. cit. 129). 

 The pileus of both specimens was orange, and the mouth rose-coloured. The 

 stipe and indusium were pure white. " Bei keinem der sonst beobachteten 

 (iiber 40) Fruchtkorper von D. phalloidea wurde eine ahnliche Farbung, wie 

 hier, auch nur andeutungsweise je beobachtet." 



Hennings (Engl. Bot. Jahrb. xxv. 505 (1898)) gives the name D. phalloidea 

 forma aurantiaca to a specimen from New Guinea with an orange-yellow 

 pileus and a snow-white indusium. Fischer (Mitt, naturf. Gesell. Bern, 

 110 (1907)) describes a form with a white volva and a yellowish-brown 

 indusium. 



Concerning Ceylon specimens, Petch (/. c.) says that the commonest 

 form has a white stalk, a white cap, and a salmon-pink net. A pure white 

 specimen is rare, though the specimens developed from " eggs " were 

 white, suggesting that separation from the mycelial strands influenced 

 the colour. (Moller's specimens, except D. callichroa^ were developed from 

 collected eggs.) Petch summarizes his observations: " Altogether, it may 

 be said that the cap may be white, pale yellow, or orange ; the stalk may 

 be white, yellow, orange, or pink; and the net may be white, yellow, 

 orange, orange-red, pink, or salmon. Examples occur with all possible 

 combinations of these colours, without any structural differences which 

 would warrant their separation as species. ... In some of the Ceylon 

 specimens the mycelium and volva are white, in others they are violet, 

 or the top of the unopened egg is purple; and there seems to be some 

 correlation between the presence of colour in the volva and mycelium, 

 and its absence from the mature fructification. ... It seems impossible 

 to maintain species on colour. In Ceylon, one is certain after gathering
