Mushrooms

Mushrooms are one of the clearest text-first systems to archive early, because the public info is already structured around effects.

CrabCodex does not just list mushroom names. It already exposes variant-to-effect mapping, effect alignment, rarity, and some baseline mechanics. That makes mushrooms a strong reference layer even before we have deep firsthand route testing.

Tracked Variants

10 public variants from A_Mushroom through J_Mushroom.

Image Caveat

CrabCodex notes that mushroom sprites are randomized in-game, so images are representative rather than strict IDs.

Current Strength

Variant lookup, effect grouping, rarity labels, and baseline mechanics.

Best Use

Quick risk reading when you want to know whether a mushroom is likely helpful, dangerous, or mixed.

Mushroom Answer

Use this page to make a quick mushroom call, not to invent certainty the public data does not support

Short answer

Confirmed

This page is best for fast effect lookup and risk reading when a mushroom choice could swing the run.

Best for

Confirmed

Checking whether a mushroom is positive, negative, neutral, mixed, or still partly unclear before you commit.

Avoid if

Confirmed

You want a fake visual-identification guide that pretends every mushroom sprite is a perfect public ID.

Fast route

Community-tested

Use the effect table first, then jump to POIs or risk-reading pages if the mushroom choice is part of a wider route decision.

How To Read This Page

The current value is in the effect mapping, not in pretending each sprite is a unique permanent visual signature.
Some mushrooms are single-effect and easy to classify, while others combine positive and negative outcomes.
I_Mushroom is intentionally kept visible as a real but still unclear public entry.

The Practical Mushroom Question

Most players are not asking, “What is the complete mushroom system?”

They are asking a smaller question:

Is this worth the risk right now?
Is this a recovery angle or a trap?
Is the effect clear enough to trust?

That is the right way to use this page. A fast, honest answer is better than a fake complete theory.

Common Mushroom Mistakes

Treating a randomized sprite like a guaranteed identity.
Reading a mixed-effect mushroom as if only the upside matters.
Taking a high-variance effect because the run feels behind, even though instability is already the real problem.
Ignoring I_Mushroom just because the current public understanding is still incomplete.

10 entries

MushroomCommunity / 社区Image / 有图

A_Mushroom

A mushroom variant currently documented with the Hallucinogen effect.

CrabCodex notes that mushroom sprites are randomized in-game, so the image is illustrative rather than a strict one-to-one visual ID.

Reference entryPortrait localizedIndexed reference

MushroomCommunity / 社区Image / 有图

B_Mushroom

A variant currently associated with one neutral effect and one rare negative effect: Refreshing and Deafening.

This is a good example of why mushrooms are worth indexing by effects instead of color alone.

Reference entryPortrait localizedIndexed reference

MushroomCommunity / 社区Image / 有图

C_Mushroom

A mushroom variant currently documented with the Lethal effect.

Short, clear, and high-risk enough that players are likely to search for it directly once the term becomes familiar.

Reference entryPortrait localizedIndexed reference

MushroomCommunity / 社区Image / 有图

D_Mushroom

A mushroom variant currently associated with the neutral Spicy effect.

Useful as part of the broader variant-to-effect lookup rather than as a standalone strategy page.

Reference entryPortrait localizedIndexed reference

E_Mushroom

A mushroom variant currently documented with the Stinging effect.

One of the simpler negative-effect variants in the current public table.

F_Mushroom

A mushroom variant currently documented with the Poisonous effect.

This pairs naturally with poison-related build and POI references later on.

G_Mushroom

A mushroom variant currently associated with the positive Yummy effect.

A compact example of a simple positive mushroom effect.

H_Mushroom

A mixed-risk mushroom variant currently documented with Mystical and Stinging.

This is one of the clearest currently documented mixed-effect mushrooms in the CrabCodex table.

I_Mushroom

A mushroom variant listed in the public roster, but currently shown without a documented effect on the CrabCodex overview table.

This is exactly the kind of real but incomplete entry the site should keep visible instead of hiding until every field is filled in.

J_Mushroom

A mushroom variant currently associated with the positive Delicious effect.

A straightforward positive entry that helps round out the current public variant set.

Giant Mushroom POI Link

CrabCodex also ties mushrooms back into the Giant Mushroom POI:

Study: +10% mushroom identification chance
Spread: +20% mushroom density

That makes mushrooms a good bridge section between consumable effects and route planning.

Best Next Page By Intent

Use POIs if the mushroom decision is tied to a route object or biome landmark.
Use How To Know When a Run Is Becoming Risky if the real problem is wider instability.
Use Codex if you are still tracing terms and systems instead of making one immediate consumable choice.

Mushrooms are one of the clearest text-first systems to archive early, because the public info is already structured around effects.
