Exposed context…

the interior flesh of the mushroom seen when the mushroom is vertically sectioned. Color of context and time associated with any color change are potentially useful.

what do you

mean by “exposed content”? Is that the mycelium beneath the fruiting body? I’ll be out there again on Saturday and will see if it is still fruiting.

If you encounter this mushroom again, please dry a sample. It would also be desirable to get a spore print and take pictures of the exposed context, noticing the background color and any staining due to oxidation.

with large tulip poplars, some red maple, beech, ironwood (Carpinus), white and chestnut oaks. Interestingly, this location also supports an uncommon native orchid: Liparis liliifolia.

Penny, did you notice…

the types of tree(s) with which these may have been associating?

The grayish-red pore surface does suggest Chalciporus. The description of C. piperatoides in BRB, however, is a total mismatch of the pictured mushroom. If you asked me how I would describe this mushroom, I would say that it’s an “all-red bolete”. The word “red” doesn’t appear even once in the description of C. piperatoides. Note the small, round pores, non-staining bright yellow flesh on the stipe, prominent reticulation at the apex, and white (not yellow!) mycelium.

The bruising was more brown than blue.

I have some more photos that I will put up. There were several of these fruiting in the same spot, and I can check there again this weekend. Is there anything else I should be looking for on these boletes?

I see some dark bruising on the pores.

But I don’t see it as blue. On the other hand, Penny says the caps bruised quickly. My collections of C. piperatus often bruise dark on the pores.

eliminates other species of Chalciporus that I am familiar with. Chalciporus piperatoides does bruise blue quickly.

Why not Chalciporus? Cap color?

This looks an awful lot like…

the rare species C. rubritubifer as described/pictured in BRB.
