PLATE 2 
Mycelium of the Rhizoctonia from a sclerotium and from the large pulp cells 
of Missionary strawberry, drawn by the aid of the camera lucida A. Zeiss 4 mm. 
8 oc.; B, C. 1.5 mm. Obj., 8 oc. Reduced about one-third. 
A. —(a) Terminal branches from a sclerotium, unstained. Most of the cells in 
this case contain one or two large oil globules and several smaller ones. (6) In¬ 
tracellular hyphae showing character of branching, crescent-shaped hyaline areas 
at the cross walls and two or three nuclei in each cell. Stained with Flemming's 
triple stain. 
B. —(a) Intercellular hyphae in cross section pushing back the elastic walls 
of the turgid pulp cells. Note the intercellular substances, possibly derived from 
disorganized middle lamellae; (6) similar to the preceding except that the inter¬ 
cellular substances appear to be in more or less distinct layers. Cytoplasmic 
contents of pulp cells indicated by stippling. Large vacuoles filled with cell 
sap. Intercellular substance or disorganizing laminae of the walls shown by 
wash drawing; (c) hyphae pushing forward between two cells which at the right 
have spread apart to form an open intercellular space.
