Notes: Im going to call this the black bolete This particular bolete i first thought it to be an Old Man of the woods Strobilomyces floccopus. Or a very dead bolete of some sort. well i picked it and it was fresh The flesh in side is black, In S.floccopus the flesh is first white but after exposing it to air truns black The flesh is tough/firm not spongy like in S. floccopus. You can easily break it apart brittle like. There have been three found in the last week of this thing/ The first one i thought it to be a decaying Old Man of the woods mushroom but the other two i found i actually examined them/ In pic # 1 is one i found first then Pic 2 is the second one found not to far from the first one both from very decaying wood.

All three specimens where found protruding from very decomposing Wood I believe it to be Red Oak. Now they where cumming from underneath the log but the decomposition is very great having turn this log into a mossy pile of sawdust almost. This wood is easily breakable in you hands mushy. Yesterday i went to the same are and looked for more but We just had decent rain last night so im going back to check it out tomorrow. Its some what of a long hike and its is in an area somewhat hard to get too having to hack your way through Briers and Roseacea to get to the small forested area where these guys are located
Kinda beaten and aged Strobilomyces. To put an epithet you will need to look at the spores. Always photograph the underside too.D.
Eastern Red oak (Quercus palustra) is a common, fast-growing oak in much of the east, and has been transplanted to the west coast as well. Could this be the wood the mushroom was growing from?
Strobilomyces in my experience are not wood degraders. So even though this looks like Strobilomyces, it might be a distinct species or possibly (hold breath) a genus novum as well. VERY important to document as many fresh and older specimens as possible, as well as confirming growth from wood.
Good luck, Eddee!
But you should in any case take herbarium specimen of these with accurate description and photos in all stages and cut and pores and stuff. Could be some interesting guys.
Not much to go on from the photos, but it might be something in the dark subgenus Porphyrellus of Tylopilus.
This is not B. mirabilis. It closley resembles S floccopus. But There are some differences that are way out of line for it. But it very well may be S. floccopus. I thought it to be some abnormal growth of S. floccopus but i have found three specimens resembling this to a T. I have seen this last year in the same place.Unfornatly the specimen i took from the area did not survive the 5 mile hike back. The wood it is growing on is Oak I believe.It is very decayed and has moss on it. but the decayed wood is Red borwn so im thinking oak. It is in a heavy forested area with mix woods of Oak Hickory Eastern Hemlock and some sort of pine perhaps Virginia pine. The name Black Bolete is what i have named it, the tubes are black also and spore print is black. These are fresh specimen in the pic the specimen shown is not more than a day old. I have been collecting in this area for several years and have constantly seen it in this area. At first i thought it to be a degrading Old man of the woods which are very common around here. There caps are velvety and soft with hairs and soft scales. The flesh spongy and as they get older they seems to harbor lots of bugs. This cap is firm crisp and black on the inside. it has scales on top of the cap but they are tough . The are no bugs in them Today I’m off to look for more of these guys. The canyon is somewhat isolated where i found these specimens. I found them looking for Chantrelles.
Haven’t heard of black bolete. The only Bolete I know of growing on logs is Boletus mirabilis. This doesn’t look like it. B. mirabilis typically has bright yellow pores when fresh, and usually a dark maroon, velvet-like cap. Specimen shown appears to have a bulbous base of the stipe, which is unlike B. mirabilis as well.
You describe this as having black flesh. B. mirabilis flesh is not black in my experience.
According to Aurora’s Mushrooms Demystified, older Strobilomyces floccopus can have black flesh.
Bottom line: doesn’t match S. floccopus in my experience. Could be a new species. Document that flesh turning color after being sliced, if possible. Really need to see the tubes, also. Would help to know the species of the log it was growing from too.
