Shear and Dodge : Patellina, Leptothyrium, Peziza 155 



Tubercularia rhois Halsted. This species collected by F. L. 

 Stevens on Rhus radicans at New Brunswick, N. J., and issued 

 and described in Seymour & Earle, Economic Fungi No. 273, 

 May, 1893, is the same fungus that was later described by Ste- 

 vens & Peterson as Patellina fragariac on fruit of cultivated 

 strawberry and is identical with Hainesia lythri (Desm.) v. Hohn. 



Hainesia epilobii Eliasson. We have seen no specimens of 

 this species but the description (1897) agrees with Hainesia 

 lythri as found on Epilobium in this country. 



Hainesia castaneae Oud. This species on Castanea vcsca 

 and H. rostrupii Oud. (1902) on Qucrcus rubra according to the 

 original descriptions agree very closely with H. lythri except for 

 slightly thicker conidia, and are probably identical. Authentic 

 specimens, however, should be examined in order to verify this. 



Tubercularia zythioides C. Massal. (1908). No authentic 

 specimen of this species has been seen but judging from the orig- 

 inal description and its association with a pycnidial form, Sclero- 

 tiopsis rubi C. Massal. which is apparently identical with Sclero- 

 tiopsis concava, this conidial form is the same as Hainesia lythri. 

 The fungus was found on leaves of Rubus caesius in Italy and 

 the author suggested that the fungus might be the conidial stage 

 and the accompanying Sclerotiopsis the pycnidial stage of some 

 unknown ascomycete. The present investigations have verified 

 this prophesy in every particular. 



Patellina fragariae Stev. & Pet. (1916). Authentic speci- 

 mens of this species kindly supplied by Dr. Stevens and carefully 

 .compared and grown in culture leave no doubt that it is identical 

 with Hainesia lythri (Desm.) v. Hohn. The form from straw- 

 berry is shown {pi. 8, figs. 3, 4). 



II. Pycnidial Stage, Sclerotiopsis concava (Desm.) n. comb. 



This is the earliest name as yet positively connected with the 

 pycnidial stage of Pezizella lythri. During the winter following 

 the discovery of his " Dacryomyces " on Lythrum, Desmazieres 

 found on decaying leaves of Rosa, the branches of which had 

 been cut the preceding summer, a fungus which he described as 

 Ceuthospora concava (1847). An examination of his specimens
