Morphology
The noun compound is fully compositional: 'ring' (circular) + 'rot' (decay) + 'fungus' (organism) straightforwardly describes a fungus that causes ring-shaped rot. This follows common noun–noun compounding patterns and is predictable for a B1 learner who knows the constituent words, so the meaning is transparent.
Etymology
Ring rot fungus comes from the way the disease looks: the fungus makes circular rings of rot and soft, watery decay around roots and sweet potatoes. So, the name tells you it is a fungus that makes those ring-shaped rotten areas.
