Upper mines brown Mushroom

[Your friendly neighborhood fart]

Please someone help me. I have been searching for days and cannot find the brown mushroom. I have search level 6 mines per a recommendation I found online and did the 5,10,15 trick to search quicker in the mines and still have not found it. I am hoping the merchant will randomly sell it but it makes me want to sob. PLEASE HELP ME.

From my experience the brown mushroom will randomly spawn on any mine floor from 1 to 19. I am 17 game days away from going into my 12th year and have only found 35 of these elusive mushrooms. Don't give up and best of luck :)
