Bothia castanella

Description

Name in North American Boletes: Bothia castanellus

Genus: Bothia

• Genus 2: Suillus

Species: castanella

• Species 2: castanellus

Common Name: “Netted Suillus”

• Common Name 2: “Chestnut Suillus”

Tells: Overall color varies through yellow, brown, pink, and chestnut. Stem is often netted, esp. at the top. Chestnut-brown cap can have red or yellow notes. Broad, angular pores bruise tawny brown.

Other Information: Likes oak. The tan, buff, or golden- to pinkish-brown pores look like a Suillus, but the dry (not viscid) cap and the netting on the stem make this a very unique mushroom. The name means “chestnut” & refers to the color of the cap, even though in some cases the cap can lighten up enough to be called “yellow-brown” or be red enough to call “pink”.

Science Notes: DNA testing has moved this mushroom from Suillus to the newly resurrected, single-species Genus Bothia – and then to adjust the species name to a feminine ending that will match.

Edibility: Unknown.

CHEMICAL TESTS:

• NH4OH (Ammonia): Cap skin has a variable reaction: red or orange with a wine-colored flash, or orange-amber with a purplish/wine colored flash. Cap flesh turns very pale yellow.
• KOH: Cap skin turns dark brown, which fades to amber or yellow-amber. Cap flesh turns pale brown.
• FeSO4 (Iron Salts): Cap skin turns grayish. Cap flesh has no reaction.
