A-H, Strawbeny cells attacked by Botrytis sp. (X 210) : A, H^'pha g^o^^^ng partly 

 between and partly within strawberry cells; B, hyphae inside strawberry cells in which 

 remnants of the protoplasm may still be distinguished ; C, hypha passing from one cell 

 into another across a short intercellular space; D, E, F, G, H, hyphae entering cells in 

 various ways (in G the hypha has pushed back a portion of the cell wall before breaking 

 through). I-M, Strawberry cells attacked hy Rhizopussp. {X 210): 7, Hypha growing 

 between the epidermis and the adjacent layer of storage cells; /, hypha gro^ving over 

 the surface of the strawberry; K, hyphae growing underneath the epidermal layer and 

 between the storage cells; L, Rhizopus sp. growing between epidermal cells (basal 

 portions of sporangiophores above and rhizoids below epidermis); M, germinating
