Mycologia 



Under the title " Selecta Mycologica," in the Annales Myco- 

 logici for 1920, Bresadola describes 92 new species of fungi from 

 various localities and appends a list of observations and synonyms 

 prepared during his study of herbarium material borrowed from 

 several European institutions. 



Dr. W. H. Ballou brought to the Garden on August 30 and 

 September 2, from White Plains, New York, a number of- in- 

 teresting fleshy and woody fungi which he had just collected — 

 among them Lactaria atroviridis, Lactaria Indigo, several species 

 of Boletus, a peculiar form of Tyromyces caesius, zygospores of 

 Sporodinia grandis, and a resupinate polypore. 



Pcstalosma scirrofaciens is described as new by Miss Nellie 

 Brown in Phytopathology for August, 1920, as the cause of a 

 hard tumor on the stems of the sapodilla tree in Florida. The 

 disease can be controlled in an orchard by destroying the infected 

 trees. 



Mr. H. A. Lee, pathologist of the Bureau of Science, Manila, 

 reports banana wilt in certain parts of the Philippine Islands. 

 Fortunately, this disease, caused by Fusarium cubense, has not 

 yet appeared upon Musa textilis, which yields the valuable Manila 

 hemp of commerce. 



A mosaic disease of corn in Porto Rico similar to that found 

 on sugar-cane, is described and figured by Brandes in the Journal 

 of Agricultural Research for August 16, 1920. The corn aphis 

 is an active agent in disseminating this disease ; and the only 

 known method of control is the destruction of infected plants. 



" The Ascomycetous Fungi of Human Excreta," by C. E. Fair- 

 man, issued July 30, 1920, is a small illustrated pamphlet contain- 

 ing historical matter, observations, a bibliography, a list of the 18 

 species previously known, and the description of a new species, 

 Cylindrocolla faecalis, found by the author in September, 191 7.
