In fio^re 3 is shown the local distribution of the dis- 

 ease in tliis State by counties so far as the writer has 

 been able to examine material. The disease no doubt 

 does much damage in every county of the State but par- 

 ticularly in the counties south of the Tennessee river 

 valley. Material of the disease has been examined from 

 the following counties: Autauga, Barbour, Bullock, Cal- 

 houn, Chilton, Clarke, Coffee, Cullman, Jefferson, Lee, 

 Mobile, Montgomery, Suuiter and Ttiscaloosa. 



OTHER SPECIES CLOSELY RELATED TO TAPHRL\ COERULESCUS. 



The following notes upon related species described as 

 growing upon species of Qucrcus may be of interest. 



Ascomyces extensus Peck .1886. Keported on leaves 



of Qucrcus macrocarpa from Nefw York state. 

 Exoascus kruchii Vuillemin. 1891. This species 

 was found by Kruch in Italy upon leaves of 

 Quercus ilici^, and is by Schroeter referred to 

 Taphria. 

 Ascomyces qucrcus Cooke. 1878. This was reported 

 by Cook in Rovenel's Auierican Fungi upon 

 leaves of Qucrcus cinera. It is identical appa- 

 rently with our Ta'phrki cocrulescens. 

 Ascomyces ruhro-hrunneus Peck. 1887. This was re- 

 ported by Peck upon leaves of Quercus rubra. 

 It is quite probable that all the above species belong in 

 the genus Taphria but their specific standing we have not 

 determined with sufficient certainty to refer to the mat- 

 ter in this connection.
