Well, I tried the experiment: put a small sample of
Hericium erinaceus spawn into my freezer overnight,
so that it was frozen solid in the morning. Then
thawed it out slowly. The spawn was unaffected by
this treatment--it appeared to do no damage at all to
the mycelium, and it was still very much alive.

In article <20010104184603...@ng-fm1.aol.com>,Spawn? Yes. Most spawn or mycelium can survive freezing, at least for
short durations. It may be a requirement for native fungi in the PNW.

But freeze a developing porocarp? I wouldn't.

how about productivity later on?, ever tested?? thomas

Thomas,
Do you mean, if I freeze the spawn, then
thaw it out and use it to inoculate bulk substrate,
will the final yield still be good? Or, if I
freeze the fruiting culture, then thaw it out,
will the yield still be good?
I haven't tried either experiment.

both, but much! more costy are the (possible) negative effects of the
first... so any real life experiences anyone? any genus??

My experience with Hericium producers is limited. The mycelium grows so
rapidly that usually only one or two flushes are produced before
discarding the colonized blocks. Since Hericium erinaceous can produce
fruiting bodies within 30-35 days (I have seen production within 28 days
from inoculation!), and a second flush within 45 days, this is not
necesarry much of a total loss in overall production.
