Re : Bisporella sp.? - 248388
Hi Danny

IKI is never good for viewing oil drops. KOH o.k. but water shows it as well but KOH may distort the droplet pattern.

I need to see the contents of the living paraphyses. Also a section of the excipulum.

Re : Bisporella sp.? - 248388
what if I only have dried material?  are the paraphyses not already dead?

Then it's over. Such fungi survive a week in the fridge, it should be no problem unless you collect in the tropics. :-)
