71. Cercospoea Sanguinarle, Pk. 



Spots large, indeterminate, smoky-brown, sometimes obscurely mot- 

 tled or subreticulate, with darker lines on the upper surface. Hypha^ 

 hypophyllous, few, scattered or subcaespitose. rather long, colored, often 

 nodulose above. Conidia, subcylindrical, obtuse, 4— S septate, colorless, 

 35—60 !J- long. 



On living or languishing leaves of Sanguinaria Canadensis, Aug., ^. 

 Y.(Peck.) 



Owing to the scattered mode of growth of the hyph^e, the fungus is 

 scarcely visible, but the large, smoky-brown spots are very con^picuons.

 Forming brown, indefinitely limited patches on the under side of the 



leaves which become dirty-yellowish above, without the formation of 

 any well defii^ed spots. Hyphse in scattered tufts, brown, continuous, 

 abruptly undulate, cro( ked and subnodulose above, 76 — 90 x 3 — 4 /-t. Coni-

 Spots indeterminate, yellowish or slightly fuscous, at length occupy- 

 ing nearly the whole leaf. Hyphse fasciculate, simple or sparingly 

 branched, torulose, especially towards their tips, remotely septate, sub- 

 fuscous, 50—70 x 5 !->: Conidia subclavate. slightly attenuated above, 1—2

Epiphyllous on indefinite, inconspicuous, suborbicular spots (2—3 

 mm.), only noticeable by being a little darker than the other parts of the 

 leaf. Hyphse short, brown, densely fasciculate on a tubercular base, sep-

 tiseptate, 100—120 p- long.
