Metasphaeria aulica (C. & E.) Sacc. 

 On dead stems of Triosteum aurantiacum Bicknell. 

 Glenmont, Albany county, May 9, 1918. H. D. House. The asci 

 are clavate, 75 to 105 micr. long, narrowly elongate at the base. 

 Sporidia 1-6 septate, mostly 5-septate, 24—28x3-4^ /x, constricted 

 at the central septum and widest in the cell immediately above this 

 septum. 



Microthyrium microscopicum Desm. 

 On dead and languishing leaves of Vinca minor L. Chit- 

 tenango Falls, Madison county, May 17, 1918. H. D. House. 



Mycosphaerella plantaginicola (Schw.) Dearness, comb. nov. 

 (Sphaeria plantaginicola, Schw. Syn. N. Am. 1806) 



On living leaves of PI ant ago ma j or L., near New London, 

 Oneida county, September 2, 1918. H. D. House. 



On these leaves are very minute, black perithecia containing globose 

 asci, 15 ft in diameter, lacking paraphyses, and with i-septate 

 sporidia, 8 x 3-3/^ /x, which agree very nearly with Schweinitz's 

 *' Sphaeria plantaginicola, No. 1806," fructification unknown. In 

 Ellis's list of Schweinitz's Sphaeriae with unknown fructifica- 

 tion, he states : "Sphaeria plantaginicola Schw. — peri- 

 thecia minute, punctiform, black, innate on both sides of the leaf, 

 subconically elevated, astomas, thickly but irregularly scattered, shin- 

 ing, becoming empty, but hard so as to be v^^ith difficulty cut." This 

 agrees with the New London collection except the last item and that 

 is true so far as the difficulty of getting the knife upon the perithecia 

 because of their minuteness. 



Periconia pycnospora Fres. 

 On dead stems of Glycine apios L. (Apios tuberosa 

 Moench), Sylvan Beach, Oneida county, August 30, 1918. H. D. 

 House. Recorded in Europe from a number of hosts belonging to 

 widely dififerent families. Two collections by Doctor Peck in the 

 state herbarium do not give the name of the hosts. 



Phoma dulcamarina Sacc. 

 • On dead stems of S o 1 a n u m dulcamara L., near Oneida, 

 Madison county, May 15, 191 8. H. D. House.
