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

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.
