July 1907] Notes from Mycological Literature 173 



Bessey, Ernst A. 



The genus Spegazzinia seems to stand rather apart from 

 any of the genera in the group Tubercularieae Dematieae, says 

 the author, on account of the peculiar structure of the spores. 

 The article, "Spore Forms of Spegazzinia ornata Sacc," in the 

 Journal of Mycology, March, 1907, shows that the statement in 

 Sylloge Fungorum is erroneous, and that the conidiospores bear 

 two kinds of spores — long-stalked spiny conidia and short- 

 stalked, smooth conidia; the two kinds of spores borne inde- 

 pendently of each other directly from the sporodochial hyphae. 

 A plate of gC'od illustrative figures accompanies the article.

A special article in Science, April 26, 1907, gives an account 

 of "A Plant-tumor of Bacterial Origin." For two years the 

 authors have been studying a tumor or gall which occurs natur- 

 ally on the cultivated marguerite, or Paris Daisy. The organism 

 has been isolated and galls have been reproduced abundantly — 

 the inoculation having been made with needle picks — on the 

 natural herb, on stems of tobacco, tomato, potato, su.^ar beets, 

 peach trees, the galls in the latter case closely resembling young 

 stages of crown gall. "It is too early, perhaps, to say positively 

 that the cause of the wide-spread and destructive crown-gall of
