Thanks Britney, but that is a little bit more than I was trying to buy!

I’ll check into the KOH + phloxine. Thanks Sava

Yes, Congo Red

Spores were mounted in Mezler’s; the rest in KOH + Congo Red. I read somewhere a recommendaton for KOH + phloxine, but have run out of phloxine. At Oregon Mycological Society we get chemicals from Judy Roger who buys them from a local store.

Nice observation!
Is that “congo red” stain?
If so, could you recommend a place to purchase some from?
I have Lactophenol Cotton Blue stain, but I think I might like the looks of the Congo Red stain better.
To me, it seems to stand out a little better than the blue.
