that, when kept continually moist from the time of production, the 

 primary sporidia will produce secondary sporidia and that, when 

 ihe primary sporidium becomes dry immediately following its 

 production, and subsequently wet, it may orerminate eithcr directly 

 or indirectly. The extent ot dryness ma}' be the deterniining factor.

It is pointed out that in accordance with the International 

 Rules, as laid down for fungi, the fungus usually known as Sporo- 

 dinia grandis, Link, must in future be called Syzygites Jiiegalocar- 

 pus, the name adopted b}^ Fries for the sexual stage. The history 

 and synonymy of the species are given in detail.

The fungi enumerated were collected by Mr. W. N. Cheesman 

 during the visit of the British Association to Australia in 1914. 

 The}»^ consist of Agayicaceae (6), Polyporaceae (32;, Hydnaceae (8), 

 Thelephoraceae i^21), Tretnellaceae (4), Gasteromycetaceae (6), Uredi- 

 naceae (1), Sphaeriaceae (9), Discomycetes (4), Deuteromycetes {2) , dind 

 Phyco niycetes ( 1 ) . 



In addition to critical notes and synonj^mj^ the geographical 

 distribution of each species is given, as far as it has been possible 

 to ascertain it. In an analysis of the distribution it is shown that 

 the fungi are on the whole of a temperate type, nearly half of 

 those enumerated being common to Europe or North America, 

 or both. 



The following new species are described: Stereiini cerifennn, 

 Peniophora Chee&inanii, P. verinicidaris, Cortichiin hiteo-aurantia- 

 ctitn, Asterostronia pershnüe, Asterostrom ella rhodospora, Heterochaete 

 Cheesinanii. 



In addition, Ihere are the following name-combinations published 

 apparently for the first time, viz: Tranietes decipiens (Berk.) Bres., 

 Irpex calcareus (Cooke & Mass.) Wakef., Odontia scopinella (Berk.)

Burger. O. F.. A bacterial r ot of cucumbers. (Phytopatho- 

 logy. III. p. 169—170. 1913.) 



The cucumber crop of Florida has been seriously injured by 

 a bacterial disease of the leaves and fruit. The first spots on the 

 fruit are from 1 to 2 mm. across, and have, a water-soaked appea- 

 rance. Each has a darker center formed of dead epidermal cells, 

 and appearing as if some insect had punctured the fruit there. The 

 Spot does not spread laterally on the surface, but the subepidermal 

 tissue turns brown. The infection reaches the vascular System, and 

 then spreads quickh% softening and browning the tissues as it ad- 

 vances. Finally the whole cucumber is reduced to a soft watery mass. 



Cultures were made from a young spot; artinciallj^ infected
