yet been reported in this country so far as we can learn. If this 

 is found to be congeneric with Sclerotiopsis, as suggested above, 

 the name Pilidium Kunze (1823) would displace Sclerotiopsis of 

 Spegazzini (1882). A thorough search for the ascogenous and 

 conidial stages of this fungus should be made where this Pilidium 

 occurs. 



The first report of the pycnidial form of Pezizella lythri on 

 strawberry in this country was that of Saccardo (1913). The 

 specimens were collected by Dearness, No. 3507 b, in Canada. 

 A portion of this material kindly contributed by Professor Dear- 

 ness is interesting, as it shows that besides the typical L. macro- 

 thecium pycnidia there are also present several sporodochia of 

 the Hainesia stage. These seem to have been overlooked by Sac- 

 cardo if they were on the specimens sent him. 



Leptothyrium protuberans Sacc. This specific name was 

 first attributed by Saccardo (1882) to Leveille, as Saccardo 

 thought at that time it was the Phoma protuberans of that author 

 (1846). Saccardo was apparently misled by Roumeguere's ap- 

 plication of Leveille's name to his No. 516 Fun. Sel. Gal. on 

 Coronaria myrtifolia, which was the first specimen Saccardo re- 

 ferred to this species (1882). Later (1884), he recognized the 

 mistake, dropped the citation of Leveille and used the name as 

 his own. Saccardo mentions (1882, 351) that his Leptothyrium 

 protuberans is closely related to L. macrothecium. An examina- 

 tion of Roumeguere's No. 516 in Ellis' herbarium shows that it 

 is identical with L. macrothecium Fckl. and Sclerotiopsis con- 

 cava (Desm.). 



Sporonema dubium C. Massal. Massalongo (1889 a) de- 

 scribed this species from Italy on Castanea. A little later the 

 same year (1889 b) the same species is described and illustrated 

 with colored figures. Through the kindness of Dr. Massalongo 

 we have been able to examine and compare part of the type col- 

 lection of this species as well as two others described and fig- 

 ured at the same time. A study of these specimens shows that 

 this species is identical with Sclerotiopsis concava, the pycnidial 

 form of Pezizella lythri. Massalongo described the spores as 

 catenulate. Whether they are slightly catenulate just before or
