copper tone

According to Smithsonian Handbooks Mushrooms (2002), R. crustosa is distinguished from R. virescens by “orange tones in its cap”. The orange and the green together reminds me of tarnished copper. Blue and gold tones are also sometimes present, as in this observation:

lists the main macro difference between R. crustosa and R. parvovirescens (R. virescens in Phillips) as being cream spore print vs. white spore print. So good luck with that distinction! He also mentions that R. crustosa has “abundant facial gill cystidia.” I have always called the quilted ones that are mainly tan or yellow “crustosa” and the green ones “(parvo)virescens.”
