Mystery mushrooms in Rune Factory: Guardians of Azuma are exactly what they sound like—odd, unidentified fungi with no clear purpose, weird stacking behavior, and vague item descriptions. They’re easy to collect and hard to understand, leaving many players asking: What are these even for?
This guide covers everything you need to know about mystery mushrooms, including how to identify them, where to find more, and whether you should eat, sell, or just toss them. Also read, How to win village contests.
🍄 What Are Mystery Mushrooms?
In-game description:

“An unidentified mushroom. Impossible to tell if it’s safe to eat or not.”
These mushrooms:
- Have no clear item category (they’re listed as “Unknown”)
- Stack inconsistently in your inventory (you’ll often see stacks of 1, 2, or 4 that can’t be merged)
- Have a low sell value (10G in their raw form)
- Can’t be eaten or used in recipes until they’re identified
🔍 How to Identify Mystery Mushrooms
Once you unlock the Mushroom Island sky area and get the side quest “Mushroom Appraisal”, you’ll meet a unique character: Mr. Fungus.

Here’s how to identify mushrooms:
- Talk to Mr. Fungus (on Mushroom Island)
- Choose how you want to appraise:
- Solo Appraisal: Uses one mushroom
- Paired Appraisal: Uses two mushrooms of the same type
- Solo Appraisal: Uses one mushroom
- Appraisal consumes the mushroom(s), so stock up if you want multiple of the same kind
💡 Pro Tip: Some mushrooms require multiple samples to be properly identified. Paired appraisals give you a better shot at success for rarer species.
Once identified, the mushroom will be revealed as either:
- Edible – Can be used in cooking or sold for a decent profit
- Toxic – Generally best to sell or discard (don’t eat it!)

Where to Find Mystery Mushrooms
Mystery mushrooms spawn regularly in Autumn and Winter regions. Keep an eye out for:
- Yellow mushrooms on the ground, especially near trees or cliffs
- Mushroom icons on your map, which mark gathering spots
You can also get them from enemies:
- Flower Mushprites (big mushroom monsters) frequently drop mystery mushrooms
- Warning: These drops are more likely to be toxic
- Warning: These drops are more likely to be toxic
💰 Should You Sell or Keep Mystery Mushrooms?
That depends on what you do with them after appraisal:
Action | Value |
Sell Unidentified | 10G (not recommended) |
Sell Edible (Identified) | Higher resale value |
Cook Edible | Great meal buffs |
Sell Toxic (Identified) | Some value, better than nothing |
If you’re tight on storage or not interested in cooking, appraise and sell. But if you enjoy cooking for buffs or giving gifts, edible mushrooms are worth holding onto.
✅ Final Tips
- Mystery mushrooms are not junk—they just require some patience.
- Appraise them in bulk to improve your chances of success.
- Identified mushrooms can help you craft better meals or boost your Gold income.
- Don’t eat or gift them before appraisal—it’s not worth the risk.
