amud beis near the bottom Rashi says the gemara is listing psakim from the Beis Medrash of Rav Ashi.
How does Rashi know this, and why is he mentioning it?

Rashi is picking up on a fairly noteworthy style of writing in our Gemara. If this would be a Beraisa, it would start "Tanu Rabbanan." For the Gemara to just start off by saying Halachos is a rarity. Rashi therefore explains that since there no "Tanu Rabbanan" or "Tana" preceding these remarks, they must be Halachos that Rav Ashi, the editor of the Gemara, decided were appropriate to put in the Gemara as Halachah l'Ma'aseh. He probably discussed these with the people in his Beis Medrash before doing so.
All the best,
Are we sure that it isn't an addendum put in by the Rabbanan Saborai? Rav Ashi and Ravina never quite finally and completely edited the Bavli and sometimes there are such addendums by the next generation of redactors.
I believe that if this would be the case it would be more commonly known and said, as the Meforshim do point when this happens. If nobody ever mentioned this was the case, the assumption is that it is part of the Gemara until proven not to be a part of the Gemara. The fact that none of the Meforshim say this, and none of the Meforshim argue on Rashi, proves that it is incorrect.
All the best,
