On fire-killed Liriodcndron Tulipifera, Oct. 16, 1894. Spo- 

 rules appendiculate at each end. 2-nucleate, 7 to 10 x 2 to 5 

 /*, oblong fusoid; the accompanying filiform process hooked 

 at the apex 20 x .75 to 1.5 /* (Nuttall, 1709).

 P. OBSCURANS E. & E., Proc. Phila. Acad., 1894, 357. 



TYPE HABITAT: On leaves of Fragaria cult., July 8, 1894 

 (Nuttall, discov. 1600, 554). 



Spots 5 to 8 mm. diameter, with a ferruginous center 

 and broad purple border, paler below. Perithecia few, scat- 

 tered, convex prominent. Sporules oblong-elliptical, hyaline 

 2-nucleate, 4.5 to 5.5 x 1.5 to 2 /x. Basidia simple, lanceolate- 

 fusoid, 8 to 12 x 1.5 /x. 



Phyllosticta fragaricola Desm. has similar sporules, but 

 the spots are much smaller, with a white center. The basidia 

 also indicate Phoma and not Phyllosticta.

On leaves of Ilex opaca, June 18, 1893 (Nuttall, 1017). 

 P. SPIRAEAE Desm? 



On Opulaster opulifolius, May 13, 1894. Sporules 10 to 

 13 x 2 fj. (Nuttall, 1508, 489).

 fusoid-oblong, hyaline, 2 to 3 nucleate, 7 to n x 2 to 2.5 /* 

 ends acute. 



Differs from Stagonospora pedunculi in its larger, flatter 

 perithecia and fusoid-oblong (not cylindrical), rather shorter 

 sporules. 

 P. UVICOLA B. & C. 



On Vitis cult. (Concord), July 4, 1893 (Nuttall, 1108, 94).
