Actually, probably closer to C. varius

Actually, this one probably comes close to C. varius. Debbie Viess showed me a somewhat similar collection from Oregon that reacted reddish with KOH – the real C. various doesn’t.

It may sound like a cliché by now, but this is a damn interesting collection. The shape and size of the spores (not Callochroid at all), but the lilac gills and the combination of KOH reactions make it hard to find a good placement… It is in Subgenus Phlegmacium, Section Phlegmacium, but can’t get it anywhere near a clade… Let me think some more.

Great observation — perfect documentation!! You’re the best Ron!!
