Dmitar posted this for observation 8871.
The five rules of collecting Boletes:
1) SPORE PRINT COLOR – please always make a careful observation of
that – this does the HEAVY LIFTING down to Genus for you. PINK,
CINNAMON, OLIVE, etc. Then you know whether’ you’re dealing with
Tylopilus, Leccinum, Boletus and so forth…
2) DISCOLORATION reactions – observe carefully
a) On sponge
b) On stipe
c) On context
3) TASTE – some Tylopili (mainly) are bitter. This can be a
huge factor when comparing similarly looking brownish/tan species.
4) MACROCHEMICAL reactions – you don’t need much. Just NAHO4 and
KOH do most of the heavy lifting in this group. Use them, make
notes and photos.
5) SLICE them – other than the context discoloration, in the case
of Gyroporus you may see a hollow stipe – that does your id right
From Wikipedia: "The Boletaceae are a family of mushrooms, primarily characterized by developing their spores in small pores on the underside of the mushroom, instead of gills, as are found in agarics. Nearly as widely distributed as agarics, they include the Cep or King Bolete (Boletus edulis), highly sought by mushroom hunters. As a whole, the typical members of the family are commonly known as boletes.
Boletes are a relatively safe group of mushrooms for human consumption, as none are known to be deadly to adults, and they are some of the most highly sought fungi for mushroom hunting. They are especially suitable for novice mushroom hunters, since there is little danger of confusing them with deadly mushrooms, like various Amanita agarics, which are the most poisonous mushrooms in the world. Some boletes are toxic, but those are not easily confused with the most popular edible ones. Boletes are easily distinguished from agarics, and easily recognized for colour, pores and thick stems and caps.
stipe is also important and observing the ornamentation of it is the first thing to do, in my opinion.Spore print vary very little in the majority of Boletaceae and a non expert eye may not tell the difference.
