Identification

Mycologists don't ID a mushroom in one glance. They build evidence: cap shape, hymenium type (gills/pores/teeth), stem features, spore print, smell, taste (chew + spit), habitat, season, region.

Each feature narrows the candidate list. After five or six observations, you usually have one or two species — or you know what test to run next.

Gills, pores, teeth, smooth, or ridges? That's the single most useful feature after cap colour.

Then: are the gills attached to the stem, free, or running down it? Are they crowded or spaced? Soft or brittle? Each detail rules out big swaths of the kingdom.

A bulbous base with a sack (volva) is an Amanita feature — and Amanitas include the deadliest species on earth. Brush soil away to see.

A ring (annulus) high on the stem suggests Agaricus, Lepiota, or related families. No ring rules them out.

Cap on paper, gills down, 4–24 hours. Reveals spore colour: white, cream, pink, brown, chocolate brown, purple-black, black.

Spore colour is the single most powerful diagnostic feature most beginners skip. It separates Agaricus (chocolate) from Amanita (white) — visually identical young.

A HIGH confidence ID means the features cleanly point to one species with no plausible alternatives. MODERATE means 2–3 candidates remain. LOW means you don't have enough information.

For anything you might eat, the rule is HIGH or don't eat. For anything you're learning, MODERATE and LOW are also useful — they tell you what to look for next time.
