PHALLOIDE^ OF CEYLON. 21 



moisture and the interior deliquesces into a yellow-brown 

 muddy liquid. The wall remains intact ; and on picking up 

 the fungus when in this condition it settles into the same 

 depressed oval or spherical shape, no matter which side is 

 placed uppermost. It resembles a bladder filled with Uquid. 

 Apparently the contents are set free only by the decay of the 

 outer wall. 



When broken, the ripe fungus has exactly the smell of 

 rotting oranges, such as may be experienced in the sorting 

 yard of an orange warehouse. Moller states that the smell 

 resembles that of the ripe fruit of Passiflora alaki, which is 

 known in Brazil as Maracuja. 



According to Ed. Fischer, Protubera belongs to the Hymeno- 

 qastrinece, not to the Pkallince. I have included it in this 

 paper, because most people would mistake it for a phalloid.
