How to identify Trooping Funnel

To correctly identify Trooping Funnel (Infundibulicybe geotropa), 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.

   The cap is initially convex, becoming depressed or funnel-shaped with age. It is typically pale buff or tan in color, smooth, and dry. The diameter ranges from 5 to 20 cm.

2. 2

   Gills

   Attachment to stem, color, and spacing.

   The gills are decurrent (running down the stem), crowded, and pale buff in color. They are often slightly wavy or irregular.

3. 3

   Stem

   Length, shape, surface, and any ring.

   The stem is cylindrical or slightly tapering towards the base, typically the same color as the cap or slightly paler. It is fibrous and solid, ranging from 5 to 10 cm in length and 1 to 3 cm in diameter.

4. 4

   Flesh

   Color, texture, and bruising reaction.

   The flesh is whitish and firm, with a mild or slightly farinaceous odor.

5. 5

   Fruiting body

   Overall growth pattern.

   The fruiting body of Infundibulicybe geotropa is typically medium to large in size, with a distinctive funnel shape.

6. 6

   Habitat

   Where it grows and on what substrate.

   Infundibulicybe geotropa is found in deciduous and coniferous woodlands, often in troops or rings. It fruits in late summer and autumn.
