22). It is very variable in size, the receptacle ranging 

 when fully expanded from two to, rarely, more than four 

 inches in diameter. The arms or branches of the interstices 

 also vary very considerably, those of the typical species 

 being usually about two-fifths of an inch (1 cm.) wide. In 

 the National Herbarium collection, we have specimens 

 identical with those from New Zealand, from the following 

 localities: — 



New South Wales — Arncliffe (W. Gayner, June, 1907); 



Gladesville (Miss M. Flockton, June, 1907); 



Mywye, Yarrangobilly (A. G. Watts, May, 1910). 



Sections of the arms or branches of the Arncliffe speci- 

 mens show considerable variation, both as regards their 

 width as well as their internal structure. In some speci- 

 mens the diameter of the branches is from 5 to 10 mm. 

 The branches have also been found to contain a single tube 

 in some cases and two or three tubes in others, even in the 

 same specimen. 



C. cibarlus var. gracilis Fischer. Syn. Ileodictyon gracile 

 Berk. (11, p. 69, t. 2, fig. 8); Clathrus gracilis Schlect. 

 (113, p. 166). 



This is much more common than the typical form and is 

 even more variable, as the receptacle ranges in size from 

 two to eight inches in diameter and the branches of the 

 interstices are from half a line to one and a half lines thick 

 in most specimens examined, but occasionally vary from 

 one to two and a-half lines in the same plant. 



The internal structure of the branches is for the most 

 part tubular but occasionally it is bi-tubular. Spores of 

 the New South Wales specimens were colourless, elongated, 

 4*5 to 7 x 2 to 2*5/*. This variety has a much wider dis- 

 tribution than the typical form, having been recorded for 

 all the Australian States except South Australia. One of 

 us, however, found specimens of a white Clathrus on several
