REPORT OF THE STATE BOTANIST I915 49 



Phoma verbascicola (Schw.) Sacc. 

 On dead stems of Verbascum thapsusL. Pecksport, 

 Madison county. H. D. House, July 2, 1915. Also collected at 

 Sand lake by Doctor Peck. 



Phyllosticta apocyni Trelease 

 On living leaves of Apocynum androsaemifolium 

 L. Green's pond, near Leeds, Greene county. H. D. House, August 

 17, 191 5. Also collected on the same host at Mechanicville by 

 Doctor Peck. 



Phyllosticta liriodendri Cooke 

 Along the edge of a woodland north of Liverpool, Onondaga 

 county, there was noticed on August 12th, a yellow poplar tree 

 (Liriodendron tulipifera L.) upon which the majority 

 of the leaves were badly disfigured by insect galls and spots upon 

 which appeared a Phyllosticta. About half of the circular brown 

 spots were clearly caused by Phyllosticta liriodendri 

 Cooke ( P . c i r c u m V a 1 1 a t a Wint.) . Most of the remain- 

 ing spots were blisterlike galls with considerable dead tissue sur- 

 rounding them and caused by the gall midge Thecodiplosis 

 liriodendri Qsten Sacken (det. Felt), and upon these spots 

 was a frequent occurrence of Phyllosticta macrospora 

 E. & E., with sporules 18-22 x 6-8 /x. One spot showed the presence 

 of a Sphaeropsis evidently related to Phyllosticta macro- 

 spora, w^hile another spot showed a Septogloeum with spores 

 33-40 X 4 /x. It is interesting to note that Phyllosticta 

 macrospora was also found at Black lake near Catskill on 

 similar spots apparently caused by a gall midge on leaves of V i t i s 

 labrusca (August 21, 1915). 



Phyllosticta variabilis Pk. 



Jamesville, Onondaga county. On leaves of Rubus odora- 

 tus. H. D. House, August 9, 1915. Professor Dearness, who 

 compared these specimens with the types of P . variabilis Pk. 

 and P . b i c o 1 o r Pk., regards all three as essentially the same, 

 although the effect of the fungus upon the leaf tissue seems to be 

 different in each case and the Jamesville specimens have a wider 

 range of spore measurements, namely, 5-8 x 3 /x.
