All Mister Mushroom Locations in Silksong
Mister Mushroom makes a mysterious return in Silksong, hidden across Pharloom as part of a secret side quest. Players can only begin the journey after uncovering a secret stone tablet in the Putrified Ducts. This guide will explain how to start the “Passing of the Age” quest, provide all seven Mister Mushroom locations, and outline how to unlock the hidden ending tied to this collectible.
How to Start the Mister Mushroom Quest
The quest begins once you find the hidden cave in the Putrified Ducts. This cave is located in the top-right corner of Pale Lake and can only be reached with the Silk Soar ability, unlocked in Act 3 within the Abyss. Inside, you’ll discover a secret stone tablet.
Reading the tablet grants the quest “Passing of the Age” and provides cryptic clues pointing to Mister Mushroom’s hiding spots. To complete the quest, you must find Mister Mushroom in seven different locations. Each time, you’ll notice small blue mushrooms on the ground, spores drifting upward, and hear faint mumbling.
When you’re near him, use the Needolin ability to draw him out of hiding.
All Mister Mushroom Locations
Below are all seven locations, their cryptic clues, and how to reach them.
1. Moss Grotto
Clue: “Under Chapel Fallen to the Monarch’s Might.”
Mister Mushroom can be found just to the right of the Ruined Chapel in Moss Grotto. Look for the small blue mushrooms and mumbling, then use Needolin to reveal him.
2. Bone Bottom
Clue: “Over Camp Collapsed to the Black Thread Plight.”
At Bone Bottom, head toward the pathway to The Marrow. You’ll need the Faydown Cloak for double jumps. First, reach the platform to the right of the entrance, then leap left to the next platform where Mister Mushroom is hiding. Use Needolin to pull him out.
3. Far Fields
Clue: “Scorched Field on Edge, Shells Black and Burned.”
In Far Fields, head southeast to the platform east of the Seamstress’s house, near the Weavenest door. Jump between platforms until you spot the mushrooms and hear Mister Mushroom’s mumbling.
4. Greymoor
Clue: “Up Towers spinning, Near the Surgeon spurned.”
Mister Mushroom is north of the left tower of Greymoor, near the Wisp Thicket entrance. Use Clawline and Cling Grip to scale platforms and walls. After reaching the top, drop down to find his hiding spot.
5. The Slab
Clue: “Cage of one who raged against the Silken Lie.”
Head to the cave where you fought the First Sinner. From the Bellway fast travel point, move east past the bench. Look for mushrooms on the ground, then use Needolin to reveal Mister Mushroom.
6. Mount Fay
Clue: “Fell Heart of Frost, Who Soars on High.”
At the summit of Mount Fay, climb using Faydown Cloak and Cling Grip. You’ll find Mister Mushroom waiting at the peak, gazing toward a bird-like creature.
7. The Cradle
Clue: “That the age may pass, this shroom its witness.”
The seventh and final Mister Mushroom location is hidden at the peak of The Cradle, the same area where you previously fought Grandmother Silk. This is one of the most challenging sequences in the game, requiring almost every traversal ability you’ve unlocked.
Start by heading to the corridor to the right of Cogwork Core, where you’ll find a slightly hidden passageway in the ceiling. From here, you’ll need to rely heavily on Silk Soar to make progress. As you ascend through this section, you’ll eventually reach the Cradle itself.
At this point, bind the severed arm of Grandmother Silk to unlock the Pale Nails skill, which is generally considered the final Silk ability in the game. Look for a narrow opening along the right-hand side, then use Silk Soar to super-jump upward and continue your climb.
Beyond this, the platforming grows more demanding, with frequent use of double jumps, pogo attacks, and grappling to advance through tight corridors and vertical shafts. Eventually, you’ll reach an unmapped zone where Mister Mushroom waits on a lonely ledge. Speak to him, and he will zoom away.
You can try to follow him toward the surface, but he won’t appear there. Instead, continue all the way to the right until you arrive at the Nameless Town. Play your Needolin at the ruined house on the far-right edge to receive the Surface Memento, a special item you can place in your personal home in Bellhart.
Mister Mushroom Quest Rewards and Secret Ending
After you uncover all seven Mister Mushroom locations, he will bid farewell and fly away from Pharloom. This completes the “Passing of the Age” quest.
To fully unlock the hidden ending, you must then defeat Lost Lace in the Abyss. Doing so will trigger a special cutscene and grant the achievement “Passing of the Age.”
Conclusion
The Mister Mushroom side quest in Hollow Knight: Silksong is one of the game’s most intricate collectibles, tying exploration, traversal abilities, and cryptic clues together. Completing all seven encounters not only rewards you with an achievement but also reveals a hidden ending that connects to the broader lore of Pharloom.
If you’re aiming for 100% completion or simply enjoy unraveling secrets, make sure you take the time to track down every location of Mister Mushroom.
