Observation 11580: Boletus chrysenteron Bull.
When: 2008-09-24
Herbarium specimen reported

Notes: Here’s another set of these darned mushrooms which I’ve probably incorrectly been calling Boletus subtomentosus. Cap is NH~4~ negative; flesh doesn’t bruise, tubes bruise dingy brownish. This one has particularly bright yellow mycelial fuzz at the base of its stipe, which is new. The amount of red on the stipes is quite variable: these show quite a bit; others are pure yellow. These are also among the smallest I’ve seen, being only between 3 and 4 cm wide. Spore print is yellowish-brown. Found under young Quercus agrifolia.

Almost all of the ones I see down here have at least some red on their stipes. I suppose I should find at least one other difference from B. subtomentosus before I declare this a new species or even variety! :)

Yellow mycelium matches

These usually have yellow mycelium at the base, but I don’t think I’ve seen the red in the stipe.
