Well explained… about the scales/background color contrast. I think I probably find more olivieri than rhacopes around here. Perhaps I’ll update some observations later today after reviewing.

thank you Fredo

olivieri vs. rachodes

In Chlorophyllum olivieri the squames and the background in the pileus are of the same color (gray-brown, olivaceous-brown) while in the other species known from North American (C. rachodes, C. subrhacodes and C. brunneum) the brown squames contrast with the white-cream background.

Here are a couple of links to Else’s articles on this group

many that I have called rhacodes. I’m wondering about how to tell the difference.

Does the context inside the stipe of your C. olivieri turn reddish when cut?

If I find any this year (need some rainfall!) I’ll post as rhacodes with a “could be” proposal for olivieri and see if I get any comments.

a few years back, Elsa altered my obs (the obs are missing)

But comment can be seen here


after that for me they are C.olivieri, they always grow in the same place.

Interesting find, Eva.

First I’ve seen this species name. Are there any traits you can point out which may be used to separate it from rhacodes?
