What the source describes

Hong Kong’s Centre for Food Safety recommends choosing firm mushrooms with a dry, sound surface and refrigerating them soon after purchase. It advises washing thoroughly and cutting near the time of cooking to limit deterioration during storage. [1]

Avoid products with signs such as abnormal smell, slime or suspicious discoloration. The guidance also says to discard a pack mixed with unknown mushroom species rather than sorting it by casual resemblance. [1]

How to use the distinction

This is fresh-food handling guidance, not a fixed shelf-life guarantee or a freezing method. Starting condition and storage history differ between packages. Refrigeration cannot establish the identity of an unknown mushroom or restore a spoiled one. [1]

A hypothetical distinction

Imagine two packages were bought today but one was already deteriorating. A shared purchase date does not create equal remaining storage life.
