Morphology
The phrase is fully compositional: 'bottom' + 'rot' denotes a decay of the lower part of a plant, and attaching 'fungus' yields a fungus that causes that condition. This follows a common noun-compound pattern (e.g., 'root rot fungus', 'stem rust fungus') that a B1 learner who knows the constituents can readily infer.
Etymology
Bottom rot fungus describes a fungus that makes the lowest part of a plant rot. The name gives a clear picture: the bottom of the plant gets rot first because the fungus lives near the soil, so it means 'a fungus that causes rot on the lower parts of a plant'.
