Intro
Key: p. 52-55 Fruiting body with a cap and stalk, or just a cap, spores
born on gills (radiating blades) on underside of cap…. Agarics (Gilled Mushrooms), p. 58; 1B Not as above….2; 2B Spore
print some other color….10; 10B Spore print pinkish to flesh-colored, salmon,
pinkish-cinnamon, or sordid reddish….11; 11B Not as above, volva typically
absent….12; 12B Not as above….13; 13B Not as above, common….14; 14B Spore print
usually deeper in color, gills not often purple, spores usually angular in end
and/or side view….15; 15B Not as above, spores typically angular in end and/or
side view, very common and widely distributed…. Entolomataceae, p. 238; 1B Growing on wood, humus, or ground….2; 2B
Stalk present, usually central or slightly off-center, on ground or sometimes
on wood….7; 7B Not with above features, gills rarely purple, and if so then
spores angular….8; 8B Not as above, spores usually angular in side view or not
angular at all….9; 9B Not as above….12; 12B Not as above….13; 13B Not as above….14;
14A Stalk fleshy, 4mm thick or more….15; 15B Spore print deep flesh-color to

Spore print and close up of lamellae would be useful. The yellow unicorn should be decidedly yellow. Even on its native substrate this one looks brown. It may be Nolanea, but not murraii, probably proxima
