Here's one for you all. I found this under a cedar in a grove of cedars...there were no hardwoods in sight. When cut, there is no apparent bruising when cut or the pore surface scratched.

I frankly stink at IDing boletes so...any ideas?

[zora]

At quick look in the North American Bolete book, I am thinking boletus curtisii ???
The comment says "The gluten has an acidic tast and stains fingers yellow. The overall aspect of this brightly colored bolete has a superficial resemblance to the genus suillus."

(just happen to be looking one up that I found today too)

here in Ontario we have really only 1 bright yellow bolete (B. ornatipes) but it tends to have a sort of gray overcast to the cap. Down where you live (why is south always down?) it might be Boletus retipes.

I was going to suggest B. ornatipes too, but it doesn't appear to have any brown staining and is extremely yellow. The B. ornatipes I find are much duller on the cap and stain brown readily when handled. I really have no clue and have never seen a bolete that was so bright yellow on the cap. I'm interested to find out what it is.

[zora]

B. ornatipes - that may be the one I was trying to identify! Thanks! It has that greyish color on the cap. And everything else is reading right in the book.

[zora]

Okay, since you are in the Bolete mood. This really looks like a bi-color to me. And there are lots of them coming out. They are usually my first of the season but they died with no rain. Now it seems the rain has kicked them back off.

Well the right thing to do with bicolors is to defer judgment to DaveW so that is what I will do. I will mention that at least superficially it looks like 2 different species in the photo. The ones with the lighter color cap have that sort of bitter bolete tylopilus kind of coloring to the cap and the dark ones just dont look the same.

Check for blue staining first ... if it's fast, that's not B. bicolor.

Then ask DaveW

bi-colors stain slowly on the pores and even slower on the flesh....and the stain will subside after 15 minutes or so.
the margin of the cap will be very sharp and brittle before they fully mature and even slightly curled
the pore surface will be very very thin and does not peel off easily
the flesh on the cap and stipe is light yellow and very firm or dense(especially on the stipe)
I find them growing in small groups...usually no more than 3 or 4

similar look-alikes would be B. sensibilis...which has a 1/4 inch or thicker pore surface that
removes very easily.Stains dark blue very fast also
The Cap is NOT firm and the stipe is usually not as bulbous or not at all bulbous

hope that helps
Bi-colors are delicious ...yummm

I've been collecting them for 12 years or more

One thing that seems to be emerging about our understanding of B. bicolor is that the blue staining/bruising is very variable, possibly on a regional basis. For the past few years I've been collecting bicolor that shows blue to blue-black bruises on the stem. It seems to me that this really just started a few years ago... at least as prominent and as dark as what I've seen lately. One or two of zora's show the staining on the stems. As for staining on the pores and/or flesh, I find this in variable intensities, and occasionally almost nil. I agree that a very rapid bluing reaction should be viewed as a non-bicolor trait. However, the stalk-stains I've been seeing have formed somewhat quickly.

There are quite a few boletes which show a red+yellow color scheme along with yellow pores. Some of these have yellow flesh, some pale yellow flesh, and some whitish flesh. Bicolor should show yellow flesh (I'll double-check). Bicolor has a very shallow layer of tubes that do not easily detach when the mushroom is young. Older specimens usually have less overall red, as the red bleaches out.

I think zora's are bicolor.

Mrogers' bolete is very interesting, and a beautiful specimen! At first I did think B. ornatipes... but a few things make me wonder... First, ornatipes typically occurs in deciduous forest.... oak, beech, birch. The one seen here was found near cedar.

I don't know B. curtisii; so I'll check it out in the big bolete book once I get home tonight. I'll see if there's anything online. To me, this bright yellow bolete with white reticulate stem and white pores seems like a real nice find!


...Just checked Mushroom Expert and... B. curtisii does not have a reticulate stem. I think this MAY be a very yellow B. ornatipes (currently called Retroboletus ornatipes).

Well, whatever it is, it sure tasted great!
