On dead twigs and branches of Larix laricina DuRoi, 

 Newcomb, Essex county. H. D. House, June 2-^, 1923. The type 

 of the variety L a r i c i s was collected by Doctor Peck at Kasoag, 

 Oswego county. Grove*" states. " I have proved by examination of 

 a long and fine series of examples that P h o m a P i n a s t r i Lev. 

 and Sphaeropsis Ellis ii Sacc. are merely growth stages 

 of Diplodia Pinastri( Lev. ) Grove." 



Macroplodia phomatella (Peck) Kuntze 

 On fallen petioles of Fraxinus americana L., Albany. 

 H. D. House, May 4, 1923. Not typical, the spore content more 

 granular than in the type, and lacking the large guttae of the latter. 

 The spores, however, are very variable, 20-26 x 8-12 /x. The type 

 was collected by Doctor Peck, on twigs of Fraxinus ameri- 

 cana L., in 1897, at West Troy. On a collection by H. D. House, 

 on Fraxinus americana, at East Greenbush, May 23, 1923, the ter- 

 minal portion of the dead twigs (the 1922 growth) contained 

 Phoma fraxinea Sacc, doubtless a stage of Macroplodia 

 phomatella, which was abundant on the 1921 growth of the 

 same twigs. 



Macroplodia juglandicola Dearness & House, sp. nov. 



Pycnidia very numerous, closely scattered, raising the epidermis 

 into pustules which are ruptured over the wide ostiola, flattened and 

 adherent to the bark and coming off with it, .75 mm in diameter, the 

 grayish center .5 mm in diameter. Conidia elliptic-oblong, 13-20 x 

 6-9' fi, but mostly about 18 x 7-8 fi, of a pale brown, uniform, 

 enucleate content, on short conidiophores 2^-3 /n wide, associated 

 in some pycnidia with numerous small spores 8-9 x 3 /x, of similar 

 shape and color. 



Albany, on dead twigs of J u g 1 a n s c i n e r e a L. H. D. 

 House, March 10, 1922 (type) and November 26. 191 5. In the 

 nomenclature of Saccardo's Sylloge this would be called Sphaer- 

 opsis juglandicola D. & H. Sphaeropsis Jug- 

 la n d i s E. & B., on dead twigs of Juglans cinerea L., col- 

 lected at Karner, Albany county. H. D. House, April 22, 191 5, is 

 easily distinguished from the above species by the large single 

 nucleus in all of the more ellipsoidal spores.
