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 Sphaeropsis hyalina B. & 

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

 that a hyaline spored species (Macrophoma) may develop 

 brownish spores at maturity (Sphaeropsis), it may involve 

 the 'co-identification of several other species of Macrophoma 

 and Sphaeropsis with identical hosts and similar spore 

 measurements. 



Sphaeropsis staphyleae Brun. 

 On dead twigs of Staphylea tri folia L. Glenmont, 

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

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

 to comjDare, 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 Henderson ia staphyleae E. &E. 



Stagonospora collapsa (C. & E.) Sacc. 

 On fallen trunk of red maple, Acer r u b r u m 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 fx., central and circular, perforating the 

 cuticle but scarcely roughening ;t 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 5^ ju, on short and indistinct basidia. 



On dead stems of Melilotus 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 diflferent. The 

 same stems contain a scanty amount of some Leptosphaeria 

 (L. viridella ?). 



Venturia cassandrae Peck 

 On languishing and dead fallen leaves of Andromeda p o 1 i - 

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

 This form on Andromeda has sporules 16-21 x 4-4 5<2 /a. The 

 species was first collected by Doctor Peck on C ham ae daphne 

 calyculata (T,.) Moench, at Kasoag and al Karner. Also on 

 Ihc same hosl at I'ecksport (House).
