It was raining too hard to take photos in the natural setting, so I took these photos outside my home the next day in diffuse 100% natural daylight from an overcast sky. Mushroom body is hardy, not decomposing noticeably at 50°F over 48 hours. Smell did not change — actually smells rather appetizing.

Best guess so far: Section GENUINAE, Group 700, possibly 707a Russula pectinatoides Peck (http://www.svims.ca/council/Russul.htm#n707a)

CAP 3-7.5 cm, dingy straw, yellow brown, or smoky brown, viscid when wet, margin widely grooved, peeling to 1/2; flesh grayish under cuticle. ODOR pleasant, fruity. TASTE mild. GILLS pallid white, adnate, some forked at stem. STEM white. SPORE PRINT cream to pale yellow. HABITAT open areas in woods.
