Mushroom & Fungi Identifier

This tool helps you identify mushrooms and fungi from field observations by considering region, season, cap shape, cap color, gills/pores, habitat, and size. We built it because mushroom identification is both fascinating and potentially dangerous, so users need structured, cautious guidance. It always includes a confidence rating and safety notes.

‍

This tool is ideal for foragers and nature lovers who want to identify mushrooms they encounter responsibly.

‍

The inputs include region, season, cap shape, cap color, gills/pores, habitat, and size category. This set allows the tool to give reasonable identifications while emphasizing caution with fungi. This tool provides educational identification guidance only; never consume wild mushrooms without expert confirmation.

Identification Summary

Based on your inputs (North America East, spring, small <2", brown, convex/rounded, “other”, forest floor), the best match is a small brown spring earth-tongue / cup-like ascomycete—most likely a species in the genus Otidea (commonly “ear-shaped” cups, often brown and springy), though your “convex/rounded” note could also fit other small brown litter fungi.

Confidence: Medium

Most Likely Species

1. Most likely: Otidea sp. (brown “ear” fungus)
   • Common on forest floor/litter in spring
   • Typically small and brown
   • Often described as rounded/convex when young or when only part of the fruiting body is visible

Alternative Possibilities

1. Second most likely: Peziza sp. (small brown cup fungi)
   • Many species are brown, spring/early season, on wood/litter
   • Young cups can look rounded/convex before expanding
2. Other plausible options (lower confidence):
   • Disciotis sp. (brown cup fungi; sometimes spring)
   • Aleuria sp. (less likely because many are more orange/red, but some can appear brownish in poor light/aging)
   • Small litter basidiomycetes (e.g., Mycena spp.) — possible if the “brown” fruit is more mushroom-like than cup-like, but your “convex/rounded” + forest-floor + season leans more cup/earth-tongue.

Why It Matches

1. Season (Spring): Otidea and many Peziza are commonly encountered in spring on forest litter.
2. Habitat (Forest floor): Both genera are typical litter/wood-associated fungi.
3. Color (Brown): These genera frequently present as brown (especially when dry, young, or partially shaded).
4. Shape (Convex / rounded): Young cups/ear-cups can appear rounded/convex before they fully expand or become clearly “cup/ear” shaped.
5. Size (Small <2"): Fits the typical small fruiting bodies seen for many Otidea/Peziza encounters.

The Tool Collective team are avid outdoorsman. In particular, the founder of The Tool Collective spent his college years studying environmental science/engineering and geosciences. These tools call back to our past college classes and combines with our avid hobbies and interests where the ability to identify various natural things in our world is not only an important skill, but a fun and rare ability in comparison to the average person. We cannot guaruntee complete accuracy with this theme of tools, but they are designed to consider the necessary variables that influence the ID and make the best guesses possible and provide additional possibilities as well as confidence levels and reasoning. they will at least get you close to the ID of whatever you are observing. Enjoy, and please don't forget to share these tools with your friends if you found them useful. Thanks!

Made with The Tool Collective's signature model. We combine an AI engine which process the user's input choices and runs it through our specifically designed logic and reasoning parameters for that tool to curate a precise and organized output. An enthusiast knowledgeable in the tool category designs the tools inputs and input choices, writes custom logic parameters, and defines the output format and requirements. The AI engine powers the system and creates a lightning fast, highly intelligent decision tool, which is always up-to-date with current pricing and publicly available information on whatever the tool is designed for. Combines all of the internets resources into one.
