You can easily buy KOH pellets or aqueous solutions of various concentrations, wherein the concentration is expressed in units called molar. If you have a jeweler’s balance, I suggest you buy pellets and make your own solution. If not, buy a solution that you can dilute to the desired concentration. For instance, a 5.5% by mass solution of KOH in water (5.5 g KOH in 94.5 g water) is 1.0 molar. When working with KOH, always wear gloves and eye protection — it’s very corrosive. Always add KOH to water, not the other way around, as mixing the two together is a strongly exothermic process, i.e. generating a lot of heat. Good luck!

seen this in the east. The other Cortinarius you have posted recently I have seen here. I wonder if they can be separated by their bar code. I have a big bottle of KOH crystals; it is easy to mix up if you have a scale which are very inexpensive. The hardest part is finding the small bottles. Are you going to Seattle?

Thanks Terri, Donna and Eva

Have you tried the Kennebec Pharmacy in Brunswick, Maine for KOH? They will mail it to you.

This is one of the most common late summer Corts locally. I have seen it for many years. By the way I am still looking for a source for KOH.

These pale to pale tan, purple gilled Cortinarius are interesting. You should start saving them for a sequence study. I don’t think anyone has done it, and it needs to be done. These look distinct to me, but we don’t have a name.
