The Rust was determined by Frank D. Kern and Eh-. Arthur, and 

 the host by J. M. Greenman. Mr. Kern says : The sides of the spore 

 in this species are inflated in a very conspicuous manner making them 

 unusually odd. It has been known before only from the type locality, 

 Florida Keys, on Pluchea purpurascens.

Mr. Frank D. Kern states : This host was determined by J. M. 

 Greenman and belongs to a section of the Carduaceae which does not 

 include any other genera known to bear rusts. 



THE PHALLOIDEAE OF TEXAS. 



BY WILLIAM H. LONG. 



The fall of 1902 was unusually wet for this State and cold 

 weather was late in coming, as our first good frost did not occur 

 until Nov. 22. Such climatic conditions brought forth a wealth 

 of fungi ; the Basidiomycetes and Gastromycetes being especially 

 abundant. It was the good fortune of the writer to collect and 

 have photographed five species of that unique and interesting 

 group of Gastromycetes — the Phalloids. 



He was especially fortunate in securing an abundance of 

 eggs, expanded plants, etc., of two species, thereby making 

 possible a study of the variations that occur in a given species. 

 The habitats of these plants are much the same, at least for 

 four out of the five species collected. They require a soil loose 

 enough so that the eggs can form readily, and it must he fairly 

 rich in decaying vegetable matter and usually not shaded. 



In an old sandy field, that had not been ploughed for seven 

 or eight months, four species were found, viz: Mntinus caninus, 

 Phallus rubicundus. Phallus impiidicus var. imperialis, and Sim- 

 blum sphaerocephalum. This field was on the north slope of
