The orange KOH reaction…

was not instant, but it did develop within about 20 seconds. The change to orange was pretty distinctive.

I get highly variable chemical reactions with many types of mushrooms (mainly boletes), presumably due to the age of the fruit body or the amount of time that elapses between collecting and testing. But I sometimes wonder about the reliability of chemical tests. In particular, do chemical tests vary regionally?

S. areolatum looks to be the likely ID for this collection.

so much time had passed. I guess that, along with the field characteristics, supports S. areolatum. I hardly ever get macro-chemical reactions on older specimens. You must have the magic touch=)

birch, hemlock, and probably other types of trees. Forest setting.

Thanks Judi. I think I still have these at home. If so, I’ll apply KOH.

KOH on surface? Could be mycorrhizal with hardwoods or conifers.

Also found in open areas and gardens according to Kuo.

(and it seems to be) there should have been nearby trees or shrubs. Were the trees hardwoods or softwoods, Dave?
