Vormioularia Doniatium (I'crs.) Fr. var. microspora ik rtir. On Acer 

 sacoharinuni. Campus, March 17. 1916. For the most part, on decorticated 

 wood. Also on inside and outside of loosened bark in the .same region. 

 3073. Many varieties of this species have been described, based for the 

 most part upon spore size and shape. The foi'm as it appears here, has a 

 remarkably small spore as compared with other forms heretofore noted. 

 So noticeable is this difCerence that a varietal distinction becomes neces- 

 sary. The foUowini; descrii)tion as differing from the species type is here 

 recorded : 



Pycnidia 150 to HOO microns (Usually 235 to 325.), varying greatly in size 

 and shape; spines 125 to 300 by 5 to 7^^, opaque, especially dark near the 

 base, pointing outward ; spores 5 to 8 by 1 to 2, hyaline. 



Melanconiales. 



Cylindrosporium Scrophulariae Sacc. & Ell. On living leaves of Scutel- 

 laria canescens, Griffey Creek. July 7, 1920. O'Neal. 3790. Differs some- 

 what from the description as follows : the broad margin around the spots, 

 is dark purple. Spores are septate and one end often broader. The three 

 guttulae not noticeable. Acervuli about 50 microns in diameter. Habit on 

 the leaves is much like Septoria Scrophulariae. 



Cylindrosporium Toxicodendri E. & E. On Uhus Toxicodendron, 1911. 

 C. E. Sutton. 3528. 



Cylindrosporium Ulmicoluin E. & E. On living leaves of Morus rubra. 

 Campus. October 15, 1915. This fungus was associated with a species of 

 Alternaria which, however, seems to follow as a saprophyte. 3G59. Spores 

 45 to 65 by 2 to 6. and mostly 4-septate. 



Gloeosporium Betularum KU. & Mart. On Betula nigra. Campus, June 

 31. 1920. These leaves were taken from young trees which had been 

 shipped from Tennessee. Though differing much from the orginal descrip- 

 tion, there seems to bo no doubt of the species being the same as described 

 from Pennsylvania. (See Am. Xat. 1882, p. 1.002.) In our specimens, the 

 acervuli are almost wholly hypophyllous and are variable in size, sometimes 

 quite large and rupturing irregularly. The most striking thing about this 

 si)ecies is the abundance of pointed .spores. They are described as being 

 obovate : however, they also have the lower end tapering to a point. 3774. 



Gloeosporium ner\isequum (Fckl.) Sacc. Belongs to Gnomonia \eneta 

 (Sacc. & Speg.) Kleb. On sycamore. University Farm. August 3, 1920. 

 Spores are for the most part. 4 to 5 by 10 to 12. The acervuli are here 

 usually on the upper .side of the leaf and along the outer edges of the vein — 

 that is. in two rows. 3793.
