Quick and dirty PCR

Hello Elisa and Dave,

Believe it or not, we have had very good luck with even simpler 
procedures than those described here.  This method has worked so far with 
dried specimens, spores, and mycelium.  

For dried (or fresh) specimens, just take a little bit of the gill tissue 
and grind it up in 500 ul of TBE, spin it down for 10 minutes at about 
6k.  The supernatant can be used in PCR straight, or more successfully, 
at a 1:100 dilution.  

This has worked well for me with dried herbarium material (fresher the 
better, though), with spores from spore prints with herbarium material 
(preferable to tissue samples if at all possible) and with mycelium grown 
on cellophane (agar screws things up, as you probably know).

Hope this helps.
