In Stardew Valley, mushroom floors are levels in the Mines that have an abundance of red and purple mushrooms and a reduced number of rocks and ore nodes. They can be identified by the presence of coloured lanterns, usually including at least one green lantern. Mushroom floors are known to spawn randomly on levels between 81 and 119. Each day, the mushroom floor moves up one level, starting from 119 and working its way down. Therefore, there is a daily chance for a mushroom floor to spawn on level 119, but it will not remain at that level indefinitely. Players can increase their chances of finding the mushroom floor by checking levels ending in 1 (e.g., 81, 91, 101, 111) multiple times, as the floor moves down one level each day.

What You'll Learn

Mushroom floors can spawn on levels 81-119
The Mines in Stardew Valley has 120 levels or floors, each divided by a ladder that either goes up or down a floor. Mushroom floors can spawn on levels 81-119. However, there are certain floors within this range that cannot become mushroom floors, such as elevator floors (ending in 0 or 5) and the last 10 floors of each section of the Mines (31-39, 71-79, and 111-119).
Mushroom floors have a greater spawn rate of red and purple mushrooms and fewer rocks and ore nodes. They also usually feature coloured lanterns, often including at least one green lantern.
The mushroom floor will only spawn the first time a player visits that floor and will disappear immediately after the player leaves. There is a 3.5% chance of a mushroom floor spawning on any given floor within the 81-119 range, provided that floor hasn't been generated as a mushroom floor before on the same day. It is possible to have multiple mushroom floors existing simultaneously, and they will all move up one level each day.
Some players have reported that the mushroom floor can be difficult to locate as it may only have a couple of mushrooms on it. One strategy to confirm a mushroom floor is to go down one more floor, as the floor immediately below the mushroom floor will be overrun by monsters (unless it ends in a 5 or 0).
In addition to mushroom floors, the Mines feature other types of floors such as infested floors and dungeon floors, which can also impact the gameplay experience.

Mushroom floors have a 3.5% chance of appearing
The Mines in Stardew Valley is made up of 120 floors or levels, divided into three sections of 40 floors each. Each floor has a unique theme, with the lowest section (floors 81-119) having a lava and dark purple theme.
The mushroom floor will only spawn the first time a player visits it and will disappear immediately after they leave. It will then move up one floor each day until it reaches floor 80, at which point it will spawn randomly on a different floor between 81 and 119. It is possible to have multiple mushroom floors existing simultaneously, and they will all move up one floor each day.
Players can identify a mushroom floor by the presence of green lanterns and an abundance of mushrooms. However, it is important to note that the mushroom floor will not always spawn mushrooms, and sometimes there may be only a few or even none on a particular spawn. Additionally, other inserted floors, such as a monster infestation, can overwrite a mushroom floor.
To maximise the chances of finding a mushroom floor, players can search for them between floors 80 and 120. If a mushroom floor is not found, players can reset the day and try again. It is worth noting that mushroom floors may be harder to find during certain seasons, as one player reported not finding any during the fall despite their efforts.

Mushroom floors will disappear after being visited
In the game Stardew Valley, the Mines consist of 120 floors, which are sometimes referred to as levels. These floors are divided into three sections of 40 floors each, with distinct themes: the first section has a brown earth theme, the second a frozen theme, and the third and final section has a lava and dark purple theme.
Any floor in the lowest section of the Mines (floors 81-119), excluding elevator floors, has a 3.5% chance of generating as a mushroom floor, provided the same floor hasn't been generated as a mushroom floor before on the same day. Mushroom floors will have a higher number of red and purple mushrooms and fewer rocks, including ore nodes. These floors will also have a variety of coloured lanterns, usually including at least one green lantern.
Mushroom floors will only spawn the first time a player visits the floor and will disappear immediately after the player leaves. The mushroom floor will then move up one floor each day until it reaches floor 80, at which point it will spawn randomly on a different floor between 119 and 81. It is important to note that the mushroom floor will not always be abundant in mushrooms; sometimes, there may be only one or even no mushrooms on a particular spawn.
Players can employ certain techniques to locate the mushroom floor. One method is to check floors 115-119 every four days or so, as suggested by some players. Another technique is to go down one floor from the suspected mushroom floor, as the floor immediately below it will be overrun by monsters unless it ends in a 5 or a 0. For example, if a player suspects that floor 83 is the mushroom floor, they can go down to floor 84; if it is overrun by monsters, then floor 83 is confirmed to be the mushroom floor.
It is worth mentioning that mushroom floors do not always exist, and multiple mushroom levels can coexist. Additionally, inserted floors, such as a monster infestation, can overwrite a mushroom floor. Players can use the Oil of Garlic effect to disable the generation of infested or overrun floors and allow mushrooms to generate instead, but this buff must be active when entering the floor.

Mushroom floors can be identified by green lanterns
The Mines in Stardew Valley is made up of 120 floors, which are divided into three sections of 40 floors each. Each floor has its own theme, with the first section having a brown earth theme, the second a frozen theme, and the third a lava and dark purple theme.
Mushroom floors can spawn on any floor in the lowest section of the Mines (floors 81-119), excluding elevator floors. They have a distinct look, with a greatly increased number of red and purple mushrooms and a reduced amount of rocks and ore nodes.
Mushroom floors can be identified by their coloured lanterns, which usually include at least one green lantern. This is a key indicator that players can use to confirm that they have reached a mushroom floor. The presence of more than two mushrooms is another sign that it is a mushroom floor.
The mushroom floor will only spawn the first time a player visits it and will disappear immediately after they leave. It has a 3.5% chance of appearing each day and will move up one floor every day until it reaches level 80, at which point it will spawn randomly on a different floor between 81 and 119. It is possible to have multiple mushroom floors existing simultaneously, and they will all move up a level each day.
Players can employ certain techniques to locate the mushroom floor. Checking floors 115-119 every four days is a recommended strategy, as is tracking the floor once its location is known. Additionally, the floor immediately below the mushroom floor will be overrun by monsters (unless it ends in a 5 or a 0), so going down one floor is another way to confirm its presence.

Mushroom floors can have zero mushrooms
The Mines in Stardew Valley is made up of 120 floors, divided into three sections of 40 floors each. The lowest section of the Mines, which includes floors 81-119, has a 3.5% chance of generating a mushroom floor, provided the same floor hasn't been generated as a mushroom floor before on the same day.
While mushroom floors typically have increased spawns of red and purple mushrooms, there is a chance that a mushroom floor may spawn zero mushrooms. This means that players may need to go through each floor at least twice to ensure they haven't missed the mushroom floor. To efficiently track down the mushroom floor, players can use floors 81, 91, 101, and 111 as reference points. By using the elevator and walking down one stair at a time, players can locate the mushroom floor in under 12 days. However, it is recommended to visit these reference floors at least three times to ensure nothing is missed.
The mushroom floor will only spawn the first time a player visits it and will disappear immediately after leaving. Additionally, the mushroom floor will not appear on floors ending in 5 or 0. Instead, it will appear on the next higher level the following day. For example, if the mushroom floor is on level 83 on the third day, it will move up to level 82 on the fourth day. This pattern continues until the mushroom floor reaches level 80, at which point it will spawn randomly on a different floor between 119 and 81.
It is important to note that the mushroom floor is not always present in the Mines. Additionally, multiple mushroom levels can coexist at the same time, with some players reporting up to three levels existing simultaneously. The mushroom floor can be challenging to locate, and players may need to employ specific techniques, such as tracking through reference floors or resetting the day, to find it.
