Boletus roseopurpureus

Common Name: None

Synonyms: 

Substrate: Ground

Location: Hardwood forests

Spore Color: Light brownish olive

Pore Surface: Yellow becoming olivaceous. Bruises blue.

Comments: 

Look for the pinkish purple colors to the cap with a yellow stem. The pore surface and the stem should bruise blue upon handling. The stem should show coarse reticulation over most of its length. Can grow solitary or in small groups.

This mushroom is somewhat uncommon. Edibility is unknown.

Chemical Reactions:

KOH - Cap dark brownish vinaceous to dull orange. Context and stem dull orange.
NH4 -  Cap pale yellow to dull orange. Context and stem dull orange.

Lookalikes:  

Boletus speciosus lacks purplish tones to the cap. It should have more of a bright red color and larger spores. Boletus rubissimus lacks the bluing reaction and has a less developed reticulum. Boletus pallidoroseus has pinkish tones to the cap and stem and less reticulation.
