How to identify Lilac Bolete

To correctly identify Lilac Bolete (Boletus separans), 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 convex, later flattening out, and ranges from lilac to reddish-brown. The surface is dry and may be slightly velvety.

2. 2

   Gills

   Attachment to stem, color, and spacing.

   Boletes do not have gills; instead, they have pores. The pores of Boletus separans are yellowish, bruising blue when handled.

3. 3

   Stem

   Length, shape, surface, and any ring.

   The stem is stout, often club-shaped, and colored similarly to the cap or slightly lighter. It may have a fine network of ridges (reticulation) near the top.

4. 4

   Flesh

   Color, texture, and bruising reaction.

   The flesh is firm and white, sometimes staining slightly blue when cut.

5. 5

   Fruiting body

   Overall growth pattern.

   The fruiting body of Boletus separans is a typical bolete shape, with a cap and a central stem.

6. 6

   Habitat

   Where it grows and on what substrate.

   This bolete is found in deciduous and coniferous forests, forming mycorrhizal associations with trees.
