Observation 9878: Tylopilus P. Karst.

When: 2008-08-22

Collection location: Scarbro, West Virginia, USA [Click for map]

Who: Eddee (eddeeee)

No specimen available

This was my first Mushroom Encounter in west Virginia I have found termedus frutings all over. I thought it to be Boletus Edulis. But After cooking some up I found out otherwise. This is a very bitter mushroom and no amount of cooking can make it palatable.

Having a bitter taste . . .

is a good bet it’s a Tylopilus as Walt suggests. A view of the hymenophore and stipe would help a lot with a virtual ID.

Not Tylopilus eximius

T.eximius is uncommon in WV and has different coloration. From the photo it is Tylopilus species. Many of them are bitter.

Don’t give up on the purple-brown boletes…

Many of them are bitter, but some which match your description and photo are quite mild. Unless you are into chemical and microscopic ID procedures, the best way to sort them out is with a field taste test. In my experience, the pinker the tubes – the more bitter the mushroom will be. Purple-brown boletes with whitish-cream tubes are often not bitter.
