THE VICTORIAN NATURALIST. 31 



analysis of its organs. Its apotheeia are very hard and tough, and not 

 readily softened by water. Probably it requires thoroughly moist weather 

 to scatter its spores, which are enormously long and exceedingly attenuated. 

 Its thallus, too, is very thin, and is composed simply of gonidia and 

 elementary filaments irregularly stuck together. 



Dr. Charles Knight, of Wellington, New Zealand, having examined the 

 specimens forwarded by me as a new species of Gomphillus, sustained 

 my opinion as to the novelty of the species, and suggested the name 

 bseomyceoides. He also kindly sent me specimens of the other species 

 calicioides, which is found in France, Italy, and Ireland, and which is, in 

 many respects, quite diverse. The new species has a thicker thallus, a 

 larger apothecium, a stouter stipes, a much larger and fungoid capitulum ; 

 and the gonidia are more irregular in size and shape, and, instead of being 

 scattered singly among the filaments, are enclosed, many together, in 

 gelatinous sacs. 



This conglobation of the gonidia of G. bseomyceoides will necessitate an 

 alteration in Nylander's definition of the genus and sub-tribe. In place of 

 saying gonidiis mediocribus parciusculis sphasricis, we must now say gonidiis 

 .aut singulatim dispersis aut in globulis gelatinosis conglobatis.

It is announced that the first general meeting of the Austral- 

 asian Association for the Advancement of Science will be held 

 in Sydney in August next, commencing on the 28th of that 

 month instead of 4th September, as at first arranged. The 

 alteration has been made in order to suit the vacations of the 

 varioas Australian Universities.
