Preserving Specimens

Post by jimmymac2 » Mon Aug 31, 2015 9:28 am

Say I found a really rare fungus and I wanted to send it to Kew (probably not going to happen any time soon), how would I preserve it? And if I still wanted to examine it for spores and stuff like that, would I use the same method? I'm having trouble right now even trying to keep a specimen for one night, in the morning it's usually shrivelled up.

For a limited time I place them in a sealable plastic container, which has been pre-moistened with water to maintain humidity. That's where I take the spore prints (on black/white paper). Crude but effective if the weather is hot. But transporting them would be another matter.

"Freshly collected fungi can (usually) be kept in good condition for several days, by putting them inside a tightly lidded plastic container, and leaving that in the fridge.

OK - I accept that other members of the family might object - but then, there is important scientific work going on here - isn't there! :lol:

If you need to keep your samples for weeks - months - indefinitely, (Or if you are sending any off through the post to be identified, or as voucher specimens), then you will need to completely dry them out.
Any moisture at all will render them prone to decomposition. (And smelly rotting fungi are completely useless to anyone).

There is plenty of info to be found by Googling for how to preserve fungi samples.

Regards,
Mike.

Thanks Mike. So does that mean fungi can be brought back from dryness ('shrivelness' is what I'm calling it)?

I'm very sorry but I've been unable to find anything about bringing back dried specimens.
