I was surprised that grossula could be so yellow/brown

but here is Lorelei’s original description of the sp., conveniently up right here on good ole MO:

“incurved margin when young, becoming convexo-umbilicate to uplifted with age, moist, hygrophanous, striate, smooth, initially yellow to brown or green-yellow, becoming pale green-yellow with age or even off-white, color of margin yellow to green-yellow; with age the entire cap almost white. GILLS strongly decurrent, initially ending at the same point on the stem apex, arcuate, thickened in age and often intervenous, edges even, yellow to green-yellow becoming slightly paler to off-white on exposure or with age. STEM central, 5-40 (-55) mm long, more or less equal 1.5-7 mm at apex, usually hollow in mature specimens, more or less smooth but may appear minutely pubescent, yellow or green-yellow. "

Again, nice find, Tim. One for the northlands!

Wood, yes

but usually very well decayed wood. In my experience C. Chrysophylla is more fuscous-brown on the cap and usually umbilicate, but these are young specimens so I wouldn’t rule it out.

They appear terrestrial….

But there could be wood down there. I’m going to go inspect further tomorrow.

Thanks guys!

or on wood?

cap doesn’t appear to be matted fibrillose, a characteristic of C. chrysophylla.
