Mycologia 



found on Potentilla in this country, we have no hesitation in re- 

 garding it as a synonym. 



Sclerotiopsis pelargonii Scalia (1903). This was based on 

 specimens that developed on leaves of Pelargonium capitatum in 

 damp chamber in Italy. We have seen no authentic specimens of 

 this species but the description applies in all particulars to speci- 

 mens of Sclerotiopsis concava which developed on leaves of the 

 same host in a damp chamber in our laboratory and also in 

 nature on P. zonale in New Jersey. Sporodochia of Pezizeila 

 lythri have been found also in September on old leaves of Ger- 

 anium maculatum, in the drug garden at Arlington Farm, Vir- 

 ginia. 



Sclerotiopsis rubi C. Massal. (1906). This was found on 

 dead spots on old leaves of Rubus caesius in Italy. The author 

 compares the species with his Sporonema dubium and Sclero- 

 tiopsis potentilla Oud. The original description agrees entirely 

 with that of pyenidia of Pezizeila lythri as found on various 

 species of Rubus from different localities in this country. Though 

 we have seen no authentic specimens of Massalongo's species 

 there seems to be no doubt that it is the. same as Sclerotiopsis 

 concava (Desm.). 



Sporonema pulvinatum Shear (1907). Comparison of the 

 type specimen of this species, which was found on cranberry 

 leaves kept in a moist chamber, shows that it is identical with 

 the pyenidial form, Sclerotiopsis concava. We also find, upon 

 examining the original material, other leaves in the same collec- 

 tion bearing amber-colored spore masses which had been referred 

 provisionally to Gloeosporium ; but which upon careful compari- 

 son now prove to be typical Hainesia lythri. Other specimens of 

 the pyenidial form on Vaccinium macrocarpum have been col- 

 lected in New Jersey and at Olympia, Washington. Judging 

 from the character of the monotype of the genus Sporonema 

 Desm. (1847) which is 5\ phacidioides, and also by study of its 

 ascogenous stage, Pyrenopeziza medicaginis Fckl., which was 

 demonstrated by Jones (1918), this is very closely related to 

 Sclerotiopsis and Pezizeila ocnotherae, but it is apparently generi- 

 cally distinct.
