An article by Warren I. Pollack in The Hosta Journal  (2020 Vol. 51 No. 1) titled Doppelgänger Hostas: Fancy Name for Look-alike Hostas, included a long list of hostas which various hostaphiles, published articles or other sources have indicated "look" the same. Some of these are, in fact, the same plant with two or more different names. Others are hostas that vary in some minor trait which is not immediately discernable to the casual observer such as seasonal color variations, bloom traits, ploidy, etc. So, as Warren mentions, hostaphiles may differ as to the plants listed but then, their opinions are based on visual observations and interpretations.

H. 'Frosted Mouse Ears', H. 'Lucky Mouse', H. 'Mighty Mouse', H. 'Moonshine Mouse Ears', H. 'Mouse Madness' and H. 'One Iota'.

H. 'Mighty Mouse' was included in two separate look-alike lists in the article. One was a list of medial (center) variegated plants while the list above includes marginally variegated hostas. Since 'Mighty Mouse' is marginally variegated, the inclusion on this list appears to be correct.
