Observation 9900: Boletus vermiculosoides A.H. Sm. & Thiers

When: 2008-08-18

Collection location: Babcock State Park, Fayette Co., West Virginia, USA [Click for map]

Who: Dan Molter (shroomydan)

Specimen available

The flesh of this bolete was harder than I expected it would be when I cut into it, a bit crispy like a watermelon rind. The bluing is rapid and intense, but fades quickly.

These were found under mixed hardwoods, mostly oak but also maple and beech.

This mushroom has a normal pore layer. The top photo shows it apparently growing on the ground under hardwoods.

Any habitat remembered?

On ground, on wood? With what trees nearby? The only species I’ve seen react in a similar fashion is Gastroboletus turbinatus, but the color change does not change with age. In fact, it seems to become darker on extended exposure to air. Maybe this is related.

“…a highly variable species”

Since the spores are a dark olive brown for B. subvelutipes, isn’t it possible that this specimen is just further along in its development than the previous one?
According to Bessette(s) and Roody (North American Boletes), it is a highly variable species with a wide range of reddish based colors for the pores.

Brown pores

The tubes are orangish brown instead of red. It could be a variety of B. subvelutipes or it could be a sister species. Barring mating compatibility tests, there appears to be no objective criteria for distinguishing between species and varieties amoung similar mushrooms.

Whether species or variety, this one is a different kind from the B. subvelutipes with scarlet pores posted here.

I suspect someone has given this mushroom its own specific epithet.

Why not B. subvelutipes?

I’ve only collected the species once and I remember the intense staining reaction. It looks a bit on the green side.
