SHORTER NOTES 



An Interesting Tropical Lichen New to the United 

 States. — Some time ago Mr. W. S. Labrot sent me a small lot 

 of lichens collected at Avery Island, New Orleans, Louisiana, 

 by Mr. Edward Mcllhenny, in January, 191 5. Among them 

 was one which was kindly determined for me by Dr. L. W. 

 Riddle as Trypetheliiim madreporiforme Eschw. (in Martins' 

 Flora Brasiliensis i: 156. 1833). As this species has been 

 known previously from South America only, where it has been 

 found in Brazil, French Guiana, and Colombia, its occurrence 

 in the United States is of considerable interest. Furthermore, 

 it is the only member of the Trypetheliaceae found in the United 

 States that has muriform spores. It should, therefore, now be 

 placed in the genus Lanrera as Laurera madreporif ormis (Eschw.) 

 Riddle in litt. comb. nov.

 lecturers and others who teach agricultural subjects. The 

 author has discussed the more important diseases of the common 

 field and garden crops necessarily very briefly, but nevertheless 

 with scientific accuracy. He apparently has a clear conception 

 of the practical needs and limitations of the modern agriculturist 

 and has undoubtedly succeeded in presenting a very readable 

 and, withal, accurate and useful little book. Professor Bessey 

 has contributed a prefatory note, besides some subject matter 

 on a few of the pages. 



Following a chapter on general information, treating of the 

 general characteristics of the disease-producing organisms, the 

 author classifies his diseases according to hosts, and treats of the 

 principal fungous diseases of cereals, of leguminous plants, of
