The cap colors

do change as they age but the colors you describe and the lack of reaction in KOH suggests to me that this isn’t it.

I use a 5 percent KOH solution.
All the R. ornatipes I’ve come across had bright yellow pore surfaces and yellow flesh that gets even yellower when cut. This one had white flesh, except for the lower part of the stem and a buff-colored pore surface. Didn’t turn my hands yellow as they usually do. Could the difference in color be due to the age of the specimen?

R. ornatipes to me too, but that should’ve stained brown in KOH from my experience. How strong was your solution?
