REPORT OF THE STATE BOTANIST FOR I924 5 1 



b u f o n i a (Berk. & Br.) Schroter, on Quercus ; and P . T i li a e 

 (Curr.) Schroter (Massariella Ciirreyi (Tul.) Sacc.) on 

 Tilia, are two additional species of this genus found in New York, 



Phragmidium americanum DieteP 



Newcomb, Essex county, on Rosa blanda Ait. H. D. House, 

 August 3, 1921. 



Phyllachora Dalibardae (Peck) Sacc. 



Newcomb, Essex county, on leaves of Dalibarda repens 

 L. H. D. House, July 22, 1922. Present only on the leaves of the 

 preceding season's growth. 



Phyllachora Wittrockii (Erikss.) Sacc. 



Newcomb, Essex county, on the terminal shoots of Linnaea 

 bo real is L., var. americana (Forbes) Rehder. H. D. 

 House, July 18, 1922. Very common upon this host in nearly all 

 of the deep swamps about Newcomb during this season. In open 

 places the host seem to be rarely infected by it. The parasitic nature 

 of the fungus causes considerable damage to the host in some places. 



Physalacria inflata (Schw.) Peck 

 Newcomb, Essex county, on decayed log ofAcer sacc h arum 

 Marsh. H. D. House, August 3, 1921. Osceola, Lewis county, 

 September 20-22, 1922. 



Peck bases the genus Physalacria onLeotia inflata Schw. 

 (Bui. Torrey Bot. Club 9 : 2. pi. IX, figs. 1-5. May 1882). Mr 

 Louis C. C. Krieger (Mar)dand Acad. Sci. Bui. 3 : 7-8. 1923), 

 after a careful study of the characters of this species, decides that 

 it really belongs to the Agaricaceae, where its nearest relatives are 

 Gloiocephala Massee, and Eomycenella Atkinson. Krieger changes 

 the generic name to Eoagaricus (E. inflatus (Schw.) Krieger, 

 1. c. p. 8), an entirely unnecessary procedure since Leotia in- 

 flata Schw. is the type of the genus Physolacria Peck. If the 

 transfer of the species to the Agaricaceae is required, the generic 

 name of which it is the type goes with it, unless there is already in 

 the Agaricaceae a prior generic name wnth which it is synonymous. 

 There is neither precedent (in modern literature at least) nor rule 

 requiring or permitting a change of generic name under such 

 circumstances.
