flexuous, torulose, septate, and minutely guttulate, 20 — 

 100 K 4—4, 5. Conidia subhyaline or tinged with olive, 

 terete, straight or curved, 45 — 150 X 3, 5 — 4. 



On leaves of Liquidambar styracijiiia^ 2227, x\uburn, 

 October 14, 1891, iVtkinson. In Jour. My col.. Vol. IV, 

 p. 115, as a note appended to C. tuberculans^. &E., Ellis 

 says: "This is very diiferent from Cercospora Liquid ambaris 

 C. & E. , which is on definite spots.'' This is the only 

 published notice of the species of which I have any knowl- 

 edge. Ellis writes me that he does not know whether a 

 description has ever been published, but that there is a 

 specimen in his herbarium marked C Liqindambaris 

 C. & E. This is probably the same as No. 77 of Langlois' 

 collection, of which I have a specimen marked C Liqiiid- 

 anibaris E. & E. At first sight it would appear quite 

 diiferent from my specimens, for the spots are brown above, 

 orbicular and quite large. There are, however, numerous 

 whitish, small, blistered spots, and a few of these are 

 changing to brown. I should say that Langlois' speci- 

 mens were in a more advanced condition than mine. The 

 chief difference in the fungus is that in my specimen 

 the conidia are much longer and more nearly hyaline. 

 This can be accounted for by the fact that I could find no 

 conidia in my specimens until I had placed them for 

 twenty-four hours in a moist chamber, where the condi- 

 tions were favorable for rapid growth. 



25. Cercospora anthelmixtica n. sp. Spots small, am- 

 phigenous, i — 3 ;;/;;/., white with narrow raised margin 

 surrounded by dark border. Hyph&3 epiphyllous, fasci- 

 culate, spreading, subflexuous, subnodnose and profusely 

 toothed, septate, fuliginous with faint reddish tinge, 30 — 

 100 X 4—4, 5. Conidia hyaline, terete, 4 — 10 septate, 

 25 100 X 4 — 4, 5. Different from C. Cheiiopodii.
