Not about this particular Daf...,but is there one authority that is respected on their opinion of whether or not the peirush attributed to Rashi in Kerisus, (and other mesechtas where Rashi might not be Rashi) is or is not Rashi?

Reb Menachem, it is good to hear from you again!
1) I have not found any leading authority who writes that the Perush attributed to Rashi on Kerisus is not really by Rashi.
Possibly, the most accesible source on the question of the Perushim attributed to Rashi that were not really written by him is the Sdei Chemed, Klalei ha'Poskim, chapter 8.
In #3 he cites a discussion about whether or not Perush Rashi on Ta'anis is by Rashi. He cites the Maharitz Chayos at the end of Ta'anis who says that it is not by Rashi. Then he discusses Rashi on Nedarim and Nazir. It is fairly well accepted that on these two tractates, it is not written by Rashi. He also quotes the Yad Mal'achi, cited by the Chida in Shem ha'Gedolim, that Rashi on Me'ilah is not by Rashi, but then he writes that the Kesef Mishneh (by Rav Yosef Karo) does refer to Rashi on Me'ilah as Rashi, even though the Kesef Mishneh refers to Rashi on Nedarim and Nazir as "the Perush" and does not call him Rashi.
2) There is a contemporary Sefer, Menuchas Shalom (which can be found on Otzar ha'Chochmah) by Rav Yaakov Chaim Sofer shlit"a, who writes (in volume 4) quite a lot about diffferent tractates where there is a doubt about whether Rashi wrote the Perush ascribed to him. He has a lengthy discussion about Moed Katan.
3) Also, it is well-known of course that on most of Bava Basra the commentary is written by the Rashbam, the grandson of Rashi. And at the end of Makos, the commentary is written by Rivan, the son-in-law of Rashi.
4) However, neither the Sdei Chemed nor the Menuchas Shalom suggest that Rashi on Kerisus is not by Rashi, so it seems to be well-accepted that Rashi on Kerisus is authentic.
5) It should be added that even on the Masechtos where it is not really Rashi, it was nevertheless written by a leading Rishon, even though we do not always know his identity. So we often find that the Acharonim ascribe great weight to the Perush attributed to Rashi on Nedarim and Nazir, for example, even though they knew that it was not actually written by him.
6) I think this discussion would not be complete if I did not mention what our prolific correspondent, Reb Shmuel Dovid Berkowitz from Lakewood, found recently when we were learning Maseches Temurah:
The Torah Temimah writes that Rashi on Maseches Temurah was not really written by Rashi. Reb Shmuel Dovid found a wonderful thing: a letter by the author of the Aruch ha'Shulchan in which he wrote that he does not agree with what his son wrote in Torah Temimah on this point, and that Rashi on Terumah is indeed by Rashi. The opinion of the Torah Temimah is mentioned in the introduction to the Hebrew Mesivta edition of Temurah. However, I think it would be worth updating this and mentioning that the father of the Torah Temimah disagreed with his son on this matter.
Kesivah va'Chasimah Tovah,

hi
you answered a question about rashi in different masechtot.
1. where is the mesivta you quoted in the letter i could not find it in the intro.
2. where is the torah temima you quoted?
3. is there any way to see the letter of the aruch hashulchan?
thank you
shlomo safdeye, United States
1) Apologies, but at the moment I cannot find the mesivta I cited.
2) The Torah Temimah is in Parshat Mishpatim chapter 22 verse 28, where Rashi writes "I do not know what the lashon 'dema' means". The Torah Temimah is at the end of #218.
3) The letter of the Aruch Hashulchan is from the periodical Sha'arei Torah part 4 kuntres 4 page 64 siman 31. I believe this can be found in Hebew Books and Otzar Hachochma but I am forwarding an e-mail with a copy of this letter.
Many thanks for your interest and apologies for my insufficient sources.
Good Shabbos
Dovid Bloom
