 New Zealand. (Journ. Bot. LIII. p. 203-212. July 1915.) 



The first part of this paper, by Cheesman, is descriptive of 

 the districts in which he collected Mycetosoa during the visit of the 

 British Association to Australia in 1914. 



In the second part Miss Lister gives cricical notes on the 

 species, and includes a table showing all the Mycetosoa now recorded 

 for the various states of Australia, for New Zealand, and 

 Tasmania. The present .collection adds 37 to the Australian 

 list, and 13 to that of New Zealand. 



A variety of Trichia Botrytis Pers. is distinguished as var. 

 cevifera Lister, on account of the waxy deposit found on the spo- 

 rangium wall and on the stalk. E. M. Wakefield (Kew).
