Phyllosticta paviae Desm. 



(Phyllosticta sphaeropsoidea Ell.) 

 (See figure 3) 

 On living leaves of Aesculus hippocastanum L. 

 Catskill, August 18, 191 5. This fungus is responsible for a very 

 unsightly disfiguration of the foliage of horse chestnut trees in some 

 localities. Certain trees near Catskill were so badly affected in 191 5 

 that by the end of August practically all the leaves were turning 

 brown and many of them falling. Fortunately the disease does 

 not appear to reoccur with equal abundance from year to year. 

 Mr V. B. Stevvart (Abs. in Phytopathology 4:399. 1914) shows 

 that the sexual stage of Phyllosticta paviae is Lae- 

 stadia aesculi Peck which occurs commonly upon the fallen 

 petioles and leaves. 



Physalospora ceanothina (Peck) Sacc. 

 (Sphaeria ceanothina Peck) 

 On dead twigs of Ceanothus americanus Linn. 

 Karner, Albany county. PI. D. House, April 191 5. The type was 

 also collected at. Karner by Professor Peck in May 1875. 



Poria attenuata Peck 



Karner, Albany county. H. D. House, no. 148, October 3, 1914. 

 Sylvan Beach, Oneida county. PI. D. House, October 12, 1915. 

 Rather common on dead hardwood sticks on the ground in moist 

 woods and thickets. 



Phyllosticta phomiformis Sacc. 



(See figure 4) 

 This fungus, common on the leaves of Quercus alba, 

 p r i n u s and p r i n o i d e s , appears to be invariably associated 

 with the insect galls caused by Cincticornia, and is therefore of a 

 saprophytic nature, although occurring on living leaves. This 

 species has been transferred to the genus Macrophoma, but all our 

 specimens have spores much smaller than described by Saccardo 

 and it is quite possible that they should not be referred to his species. 



Phoma galactis Dearness & House, n. sp. 



Pycnidia subcuticular, hemispheric, black, thickly scattered, 200 ^ 

 •in diameter ; spores pyrif orm, hyaline, on basidia of about the length 

 of the spores which are very small, oblong, 2^/^-3 x i/^ ^t.
