NUMULARIOLA gen. nom. nov. 



Nummularia Tul. Sel. Fung. Carp. 2: 42. 1861 — Sacc. Syll. Fung, 

 i: 396. 1882. Not Nummularia (Riv.) Rupp. Fl. Jen. 18. 1745 —

 PI. 2 : 300. 1821 



In many of the early European treatments of the flowering plants, 

 the Moneywort was known as Nummularia or Numularia, having 

 the same derivation as the fungus genus Nummularia Tu- 

 lasne. Numularia of Gilbert and S. F. Gray is now usually 

 merged into Lysimachia, but still recognized as of subgeneric rank, 

 was not an invalid name when proposed, and would still be the 

 valid name if that section of Lysimachia should be restored to 

 generic rank. 



Numulariola atropunctata (Schw.) comb. nov. (Sphaeria 

 atropunctata Schw., D i a t r y p e atropunctata Berk., 

 Hy poxy Ion atropunctatum Cooke ; Anthostoma 

 atropunctata Sacc.) Found chiefly on dead limbs of Fagus 

 and Quercus in this State. 



Numulariola discreta (Schw.) comb. nov. (Sphaeria dis- 

 creta Schw., N u m m u 1 a r i a discreta Tul.) Frequent on 

 dead branches of Malus, Aronia, Amelanchier etc., and on the apple 

 tree regarded as the cause of the "apple blister canker" disease. 



Numulariola nummularia (Bull.) comb. nov. (Hypoxylon 

 nummularium Bull. Champ, de Fr. t. 468. f. 4. 1789)" 

 Sphaeria CI y pens Schw. ; Nummularia B u 1 1 i a r d i 

 Tul.) Frequent on dead limbs of oak, especially Quercus alba 

 L., and occasionally on Fagus grandifolia and other 

 species.
