originally described in S p h a e r o p s i s and if the mature spore is 

 brownish, it is rightly to be called S p h a e r o p s i s h y a 1 i n a B. & 

 C, the prior name. If further investigation shows beyond doubt 

 that a hyaline spored species ( Macrophoma ) ma}- develop 

 brownish spores at maturity (S p h a e r o p s is), it may involve 

 the co-identification of several other species of M a c r o ]:> h o m a 

 and Sphaeropsis with identical hosts and similar spore 

 measurements. 



Sphaeropsis staphyleae Brun. 

 On dead twigs of S t a p h y 1 e a t r i f o 1 i a L. Glenmont, 

 Albany county, May 9, 1918. H. D. House. The spores are 

 21-24 X 10-12 /,c. Without authentic European material with which 

 to compare, it is impossible to positively identify this with S. 

 staphyleae Brun., although there is nothing in the descrip- 

 tion of that species to exclude our material. The same twigs con- 

 tain an abundance of H e n d e r s o n i a staphyleae E. & E. 



Stagonospora collapsa (C. & E.) Sacc. 

 On fallen trunk of red maple, Acer rubrum L. Sylvan 

 Beach, Oneida county, May 16, 1918. H. D. House. 



Stagonospora meliloti Dearness & House, sp. nov. 



Pycnidia thickly scattered on the more or less blackened areas 

 of the stems, subcuticular, depressed hemispheric, 150 to 200 micr. 

 in diameter ; ostiola 40-50 fi, central and circular, perforating the 

 cuticle but scarcely roughening it to the touch. Conidia 1-3-septate, 

 hyaline, sides even or slightly curved, rounded at the ends, con- 

 stricted at the septa, 15-20 x 5-7^ /*, on short and indistinct basidia. 



On dead stems ofMelilotus alba Desv. Albany, July i, 

 1918. H. D. House. Type in the New York State Museum her- 

 barium. Stagonospora desmodii E. &E. has certain char- 

 acters in common with this, but the spores are quite different. The 

 same stems contain a scanty amount of some L e p t o s p h a e r i a 

 (L. viridella ?). 



Venturia cassandrae Peck 



On languishing and dead fallen leaves of A n d r o m e d a p o 1 i - 

 folia L. Pecksport, Madison county, July 10, 1918. H. D. House. 

 This form on Andromeda has sporules 16-21x4-41/2 ix. The 

 species was first collected by Doctor Peck on C h a m a e d a p h n e 

 calyculata (h.) Moench, nt Kasoag and at Karner. Also on 

 ihe same liosl at Pecksport ( f louse).
