PPEN LETTERS: 
IN YOUR June number and ina Aulletin of the South Carolina Agrictl 
tural Experiment Station, Dr. A. P. Anderson quotes me as identifying the 
Tilletia found on rice in South Carolina with Z72/etia corona Serib. The 
resemblance is certainly striking, but in writing Dr. Anderson I did not intend 
to express a final opinion in the matter. I had not at that time seen@ 
description of the Japanese 7i//etia horrida Tak. It now seems to me - 
the differences in the manner of affecting the host plant, the spore mass beiig 
included by the glumes in 7. Aorrida and conspicuously exserted in 7. carats 
should be considered of sufficient weight to separate the species a 
until such time as their life histories can be carefully studied. Theref ee 
should prefer to call the South Carolina specimens 77//etia horrida Ta 5 
my opinion much more confusion is occasioned by the hasty Gain 
many forms under one common name than by tentatively recognizing. 
many forms as independent species.
