Concentrating first on the Boletes,
Imleria badia, the Bay Bolete.
The first one we saw was the Bay Bolete, notable because of its often notably darker brown and matte to dry polished cap - not normally viscid and almost entirely under Pines as in Suillus bovinus, the lighter warmer brown of the Bovine Bolete. The cap is difficult to peel.
A moderately sized medium-large Bolete, with a cap 5 - 15 cm across. The stipe is reddish-brown narrow vertical lines over the paler background, no reticulation except maybe at the apex, getting streakier as it gets older. Stripes can look surprisingly reddish. May be a pale to whitish zone at the apex and possibly the base, where there may be some whitish mycelium.
The pores are white to pale yellowish, yellow-green to olive when older, bruising a rather dull greyish blue, perhaps somewhat slowly.
When cut you may get a bit of blue in the flesh and maybe a little bit of wine-red immediately under the cap. Or bluish in the cap flesh, slight reddish-brown in older specimens, not blue in the stem, from the images on the internet.
Generally found under conifers or Beech in the South (maybe almost anything). However on occasion it can be a lighter much more orange brown, quite viscid when wet. Spores are olive-brown.
A drop of ammonium hydroxide solution turns the cap cuticle a greenish to bluish colour. Application of ferrous sulphate solution causes the flesh to stain a dull bluish-green, while the pores turn golden brown with a drop of dilute potassium hydroxide
