How to identify Scarletina Bolete

To correctly identify Scarletina Bolete (Boletus luridiformis), 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.

   Cap is initially convex, becoming more flattened with age. The color ranges from tan to brown, often with reddish or orange hues. The surface is dry and smooth, sometimes slightly velvety.

2. 2

   Gills

   Attachment to stem, color, and spacing.

   N/A (bolete with pores). Pores are small, round, and bright red, bruising blue when handled.

3. 3

   Stem

   Length, shape, surface, and any ring.

   The stem is stout, club-shaped to cylindrical, and typically red or reddish-pink, often with a fine network of ridges (reticulation) near the top.

4. 4

   Flesh

   Color, texture, and bruising reaction.

   The flesh is yellowish, often staining blue when cut or bruised, especially in the stem. This bluing reaction is a key identifying feature.

5. 5

   Fruiting body

   Overall growth pattern.

   Medium to large size, with a distinctive red pore surface and stem.

6. 6

   Habitat

   Where it grows and on what substrate.

   Found in deciduous and coniferous forests, forming mycorrhizal associations with trees.
