Mushroom Image

Cap

5-10 cm. Starting convex and then flattening out. Very variable in colour from dark brown to tan to olivaceous to yellow and even red. The surface is finely hairy (tomentose) or smooth as it ages and can crack, revealing a yellow or white flesh.

Pores

Angular, pale to bright yellow and can be adnate, adnexed, notched or decurrent. Can turn blue where bruised. Xerocomoid Boletes have pore tubes that will generally split in half if the cap is torn apart, other Boletes pore tubes will normally separate and remain whole leaving them unbroken.

Stem

5-10 cm long, 1-2 cm diameter. Can be cylindrical, tapered or club shaped.  Usually pale yellow with a pink/brown base and can have course reticulation at the apex. Can look fibrous with tiny floccules.

Flesh

White to pale yellowish, sometimes blueing slightly in the cap but not always. The base of the stem is pinkish brown.

Habitat

Associated with broadleaf trees but can be found with coniferous trees.

Possible Confusion

Rusty Bolete (Xerocomus ferrugineus) is very similar but lacks the pinkish brown in the stem base and has whiter flesh.
Poplar Bolete (Xerocomus silwoodensis) is again similar but has a more pronounced recticulum and grows with Poplar.
Goldenthread Bolete (Xerocomus chrysonemus) has wider pores and yellow hyphal cords joined to the base.

Taste / Smell

Sharp and acidic.

Frequency

Thought to be fairly common but probably misidentified and often under recorded.

Spores

Olive brown. Subfusiform to ellipsoid.

Other Facts

Not the best edible when fresh but like many Boletes, the flavour and texture can be improved by drying.

  1. I am not sure about this description, I’ve found many other sources, including wikipedia, claim that the Xerocomus subtomentosus mushroom does NOT have decurrent pores. The confusion might be because several subtly different species share the same name in this case.

    Here are some places with descriptions of this mushrooms that are different in this respect:
    https://en.wikipedia.org/wiki/Xerocomus_subtomentosus (Note it says “Hymenium is seceding”)
    https://www.123pilzsuche.de/daten/details/Ziegenlippe.htm (Excuse the different language, but you can see in the pictures they are not decurrent)
    https://www.mushroomexpert.com/xerocomus_subtomentosus.html (Some here are very slightly decurrent, extremely subtle)

      Due to your comment I will change the description as with much research, the subtomentosus can have adnexed, adnate, notched or decurrent pores. The sources I trust are Fungi of Temperate Europe by Thomas laessoe and Jens H. Peterson, British Boletes by Geoffrey Kibby the First Nature website and colleages who I work with. No-one really mentions whether they are decurrent but the images clearly show some of the mushrooms having decurrent pores. Wikipedia is not a trusted source although I’m happy to use it in conjuntion with other sources.
