On Aralia nudicaulis. Phlox, Wisconsin, July 11, 1914. The 

 smaller and continuous sporules are probably immature but are 

 in the majority in the material examined. There is evidence 

 that the affected tissues fragment and fall away, for the most 

 part probably, before the full maturity of the fungus. 



A collection on leaves of cultivated Phlox made at Racine, 

 Oct. 1, 1896, should probably be referred to Septoria phlogis 

 Sacc. & Speg. The spots have no colored border; the epiphyllous 

 pycnidia are delicate ; the sporules range from 25—75 x l-l 1 /^- 

 Apparently the spots are brown and angular at first becoming 

 white or sordid and more rounded in outline with maturity. 



More or less of the distal portion of the leaves of Carices in 

 Wisconsin are often observed to be dead and on examination 

 scattered pycnidia are found. Specimens showing hyaline gut- 

 tulate sporules 10-13 x 2 1 / 2 -3 J u were referred to Phyllosticta cari- 

 cis (Fckl.) Sacc. in the provisional list. Of a collection on Carex 

 sp. indet. at Racine it was noted ' ' sporules 10-13 x 3-5/x mostly 

 becoming uniseptate; some of the sporules germinate without 

 forming a septum." A collection from Gaslyn on Carex pennsyl- 

 vanica bears 1-2 septate sporules 15-16x4/*.; one from Spooner 

 on Carex intumescens has biseptate sporules 16x4/x; one from 

 Oakwood on Carex sp. indet. shows 1-2 septate sporules 

 12-18 x4-5/i. while in a collection on Carex pcnnsylvanica made 

 at Neopit the sporules are 18-26 x 4-5/a, 3-4 septate. These 

 seem to me to represent various degrees of maturity and devel- 

 opment of a single fungus which is perhaps Stagonospora cari- 

 cinella Brim. The Neopit collection bears also a Septoria hav- 

 ing pycnidia about 100//. in diameter which contain sporules 

 37-55 x i/ 2 -V 



A specimen on Carex retrorsa collected at Athelstane agrees 

 with the description of Stagonospora paludosa (Sacc. & Speg.) 

 Sacc. 



Septoria acerclla Sacc. On Acer Negundo. Galesville. This 

 agrees with the description given by Dr. Martin in "Septorias 

 of North America". (Journ. Mycol. 3:19.) 



Septoria lophantlii Wint. On Agastaclie scrophulariaefolia. 

 St. Croix Falls. In these specimens the sporules vary in length 

 up to 80ju.
