Hi,
I tend to leave most poroid’s alone – life’s too short! 😆
However, (although I haven’t used it myself), I understand that Clemenҫon’s solution is widely used to soften/rehydrate woody material (sometimes allied with mounting in ammoniacal solutions), prior to microscopy.
See: –
http://fungus.org.uk/nwfg/chemdec99.htm
for an explanation of the chemicals which are used to make-up Clemenҫon’s (and other) mycological reagents etc.
Regards,
Mike.
