With the release of The Vallis Undermind update, players gained access to a new activity called Deepmines Bounties, which features multiple objectives and hidden additional tasks.
During these Deepmines Bounties, players can collect Mushrooms scattered throughout the area, which are required for completing the Field Guide and increasing their Nightcap Rank.

How To Collect Mushrooms?
Mushrooms can be collected while exploring the Deepmines Bounties, which usually involves completing objectives scattered throughout the underground areas of The Vallis Undermind update.
As you progress through different zones within the Deepmines, you may encounter Mushroom Patches that provide random species depending on the specific area you are currently exploring.
Interacting with these Mushroom Patches allows you to collect the mushrooms and grants you a temporary buff associated with the particular species that you have gathered.
Tips on Mushroom Effects
It is a good idea to keep track of each Mushroom’s buffs by collecting its specimens, allowing you to adapt to different encounters efficiently.
Some Mushrooms may cause unusual effects, but most provide more advantages than drawbacks, with side effects that are often harmless or purely visual.
Every time you exit a Deepmines Bounty, all Mushroom effects are removed, requiring you to collect new ones when starting your next run.
Verdict
Mushrooms can play an important role in completing the Field Guide, but they also make Deepmines Bounties more engaging by providing helpful buffs during missions.
Gathering as many Mushrooms as possible can make objectives easier to complete, especially when their effects complement your playstyle or Warframe setup.
Since mushroom effects vary by species, it is wise to pay attention to how each one alters your performance and adjust your weapon choices accordingly.
