How to identify Unidentifiable Mushroom

To correctly identify Unidentifiable Mushroom (N/A), check each of these features in order. Misidentification is the most common cause of mushroom poisoning, so cross-reference multiple sources.

Step-by-step identification

1. 1

   Cap

   Shape, color, surface texture, and diameter.

   Shape, size, color, and surface texture are unknown and highly variable. Could be convex, flat, umbonate, depressed, smooth, scaly, sticky, dry, etc.

2. 2

   Gills

   Attachment to stem, color, and spacing.

   Presence, attachment, spacing, color, and edge characteristics are unknown and highly variable. Could be absent, adnate, adnexed, decurrent, free, crowded, distant, white, colored, smooth, or serrated.

3. 3

   Stem

   Length, shape, surface, and any ring.

   Presence, shape, size, color, surface, and presence of a ring or volva are unknown and highly variable. Could be central, eccentric, lateral, absent, cylindrical, club-shaped, tapering, smooth, scaly, or hairy.

4. 4

   Flesh

   Color, texture, and bruising reaction.

   Color, texture, and bruising reactions are unknown and highly variable. Could be white, colored, firm, soft, brittle, or change color upon cutting/bruising.

5. 5

   Fruiting body

   Overall growth pattern.

   Highly variable, as this category encompasses any mushroom that cannot be identified. Fruiting bodies can range from agaricoid (gilled mushrooms) to polyporoid, resupinate, or gastroid forms. No consistent macroscopic features can be described.

6. 6

   Habitat

   Where it grows and on what substrate.

   Unknown and highly variable. Could be found on wood, soil, dung, moss, or other substrates, in various ecosystems (forests, grasslands, urban areas) and climates.
