100 THIRTY-EIGHTH REPORT ON THE STATE MUSEUM. 
Cylindrosporium veratrinum, S. é W. 
Plate 1, figs. 10-12. 
Living leaves of Indian poke, Veratrum viride. Adirondack moun- 
tains. June. ‘ 
This fungus appears to me to be ambiguous, between the genera Cy- 
lindrosporium and Ramularia. Distinct, though short hyphe are pres- 
ent; and the spores are very long and clearly septate, in violation of 
the generic character of Cylindrosporium. The fungus is sometimes 
either associated with or followed by oblong black spots or patches, 
which are sometimes confluent, and which bear minute black perithecia 
containing oblong or cylindrical spore-like bodies about .ooo2 in. long. 
Ovularia moniloides, 7. é UM. 
Plate 2, figs. 1-4. 
Living leaves and dead branches and aments of sweet gale, Myrica 
Gale. Adirondack mountains. June. 
A very variable species. Sometimes the spots are few and scattered, 
again they are numerous, small or large, and often confluent, occupying 
nearly the whole leaf. Sometimes the fungus extends to the branches, 
both dead and living, which it surrounds with its white flocculent patches. 
Peronospora Arthuri, Far. 
Living leaves of evening primrose, Hnothera brennts: Albany. June. 
Peronospora Halstedii, ari. 
Living leaves of Ambrosia trifida, North Greenbush. Sept. 
This often grows upon the spots occupied by Protomyces polysporus. 
Peronospora Potentillaz, De By. 
Living leaves of purple avens, Gewm rivale. Adirondack mountains. 
June. 
Entyloma Sanicule, 7. sp. 
Plate 1, figs. 7-9. 
Spots numerous, small, close or subconfluent, orbicular or subangular, 
varying in color from whitish or greenish to brown or reddish-brown ; 
conidia amphigenous, filiform or linear, straight or curved, colorless, 
.0012 to .0024 in. long, .o0008 to .coo1 broad. Sometimes plurinucle- 
ate ; spores subglobose, .00055 to .o0065 in. broad. 
Living leaves of sanicle, Sanicula Marilandica. North Greenbush. 
May. 
The very long slender conidia are a distinguishing feature in this 
species. 
Cercospora Violz, Sace. 
Living leaves of violets, Viola blanda. Osceola. Aug. 
In our specimens the spores are shorter than the dimensions given for 
the type, from which it is probable that they are a variety. They are 
.003 to .004 in. long, but pluriseptate as in the typical specimens. 
Cercospora Cephalanthi, 7. ¢ 4. 
Living leaves of Cephalanthes occidentalis. Karner. Aug.
