I agree that both R. pectinatoides and mutabilis are very similar in size and color, as well as both having tuberculate-striate margins. To my eye, however, pectinoides is a paler hue … a bit creamier rather than tawny or orangey like mutabilis; and the pinkish/reddish spots of color on the cap of pectinatoides are concentrated along the striations of the margin (Kuo); whereas with mutabilis the reddish-brown splotches are darker and are concentrated toward the center of the cap. I think these subtle differences are best illustrated by the images in my Ob. #211877 (R. pectinatoides) and Ob. #175003, which also offers a good illustration of what I have described above. I truly appreciate your attention to and consideration of my observation. It’s always good to have someone to keep you on your toes=)
