Description

Name in North American Boletes: Gyrodon merulioides

Genus: Boletinellus

Genus 2: Gyrodon

Species: merulioides

Common Name: “Ash Tree Bolete”

Tells: Yellow pores have distinct veins across the surface, & often stain slowly blue.

Other Information: Yellow cap flesh may slowly stain blue-green. Cap bruises a dull yellow-brown. Stem bruises red-brown.

Science Notes: This is a particularly interesting mushroom from the scientific point of view, with all sorts of odd bits of trivia in addition to the distinctive veins. E.g., it’s relationship is with a parasitic aphid that preys on Ash Trees rather than with the trees themselves. It’s worth a bit of reading if your curious about such things. DNA testing moved this mushroom from Gyrodon into Boletinellus, along with all the other North American Gyrodons except G. lividus.

Edibility: Good.

CHEMICAL TESTS:

NH4OH (Ammonia): Cap skin turns blackish, then fades to dull red or orange.
KOH: Cap skin turns blackish, then fades to dull red or orange.
FeSO4 (Iron Salts): No data.

North American Boletes reports it as olive-brown. Nothing unusual.
