Note the noncollapsed and collapsed mesophyll cells, and the rather sharp separation of the two tissue types (X40); B) Col- lapsed mesophyll area exhibiting empty appearence due to lack of hyphae (X40); C) Stroma-bearing tissue exhibiting concentration of hyphae beneath stromata. Note bending of mesophyll by stroma (X75); D) Hyphae packed into intercellular spaces caused by collapse of mesophyll cells (X470); E) Noncollapsed and collapsed cells in close association. Note large intercellular hypha (X470); F) Undisturbed hypodermis under stroma (X470). c = collapsed mesophyll cell(s) h = hypha(e) n = non-collapsed mesophyll cell(s) s = stroma v = transfusion/vascular tissue p = hypodermis 103.
