EFFECT OF THE ENDROT FUNGUS ON CRANBERRIES 
hyphae entered a cell through a single opening (Fig. 2, C)- That the hyphae 
readily grow through the protoplasm and into the vacuole is evident (Fig. 
3, A), and in this case as in some others the nucleus persists and is readily 
distinguished after the cytoplasm is largely disorganized.

thick cuticle, small, nearly rectangular epidermal cells, and below these the storage cells 
of the cranberry. Between and within the storage cells are hyphae of Fusicoccum putre- 
faciens. X 450. B. Section showing hyphae of F. putrefaciens between cells of cranberry 
and in three cases branching at cell intersections. X 450. C. Section of cranberry tissue 
showing single hypha between epidermal cells and subjacent storage cells. X 450. 
With the apparent exception of the seeds, the fungus grows readily in 
all parts of the berry. Hyphae are found in the vascular bundles, as well 
as in the cells lining the seed cavity (Fig. 3, A) and in those immediately 
below the epidermis (Fig. i, A and C). 
In the slides examined, no case was found in which the mycelium had 
penetrated the cuticle, although in numerous instances the hyphae grew 
close to it and even under it for considerable distances. The fruiting bodies 
(Fig. 3 B) apparently develop outside the epidermal cells (the color-bearing 
cells) under the cuticle, which latter they finally rupture mechanically.
