THE PHALI.OIDEE OF CEYLON. 181 



There is practically no disc in fully matured specimens. The 

 upper end of the stalk is at first closed by a thin membrane 

 as in Dictyophora ; this membrane becomes tough in alcohol, 

 and then appears to be a permanent covering, but, presumably, 

 it vanishes soon after the receptaculum has expanded, and 

 leaves the black gleba adhering to the bases of the arms. 

 Before this happens the disc viewed from above looks like 

 that of a sea anemone : in the centre is a small clear circular 

 area with a crenate border : from the indentations of this 

 border white lines extend through the black gleba towards 

 the junctions of the arms, while the whole is fringed by the 

 long white arms. The white lines are slight thickenings of 

 the evanescent membrane, one between each pair of arms. 



The upper (ventral) surface of an arm bears two thin longi- 

 tudinal wings, often connected here and there by netted folds 

 between them. A single cavity extends the whole length of 

 an arm, and the cavities of adjacent arms may be continuous 

 or distinct, even on the same specimen : there is a cross wall 

 between each pair of arms, but it is sometimes perforated. 



Unexpanded specimens when removed from the volva have 

 a short conical stalk surmounted by a somewhat flattened 

 spherical head. The head consists of the black gleba enclosed 

 in a meridional series of white arms. The arms are closely 

 applied to the gleba throughout their whole length, but they 

 do not hide it completely. They meet in a point at the upper 

 pole, and in the last few millimetres are regularly wavy. 



This species has been beautifiilly illustrated by Penzig, and 

 my specimens match his figures so exactly that drawings of 

 them would be merely duplicates. 



ADDENDA. 



Whilst the foregoing account was in the Press, the follow- 

 ing additions to our knowledge of Ceylon Phalloids have been 

 made : — 



A red Phallus, most probably Thwaites's " new species of 

 Phallus of a deep red colour," has been found at Hakgala 

 (5,800 feet) : it is closely alhed to, probably identical with,
