Identification key
Identify a mushroom by what you can see

How the key works
We record the traits of each species: what is under the cap, what it grows on, how it grows, cap color and size, ring, cup, spore print and season. Each answer keeps the species that fit it. A species with a ring on some specimens and not others fits either answer.
Results are listed by name. When nothing fits every answer, the key shows the species that fit the most. A match is a name to read up on, not an identification: compare it with its lookalikes before you trust it.
