Mushroom not growing on other mushrooms. 2
Mushroom with gills on its underside. 3
Gills absent. 5
Growing shelflike on wood (or, if not, then gills concentric rather than radial); mushroom very tough and leathery, corky, or woody (try tearing it in half); gills tough and hard, sometimes maze-like; cap frequently (but not always) with concentric zones of color. Polypores
Not completely as above. 4
Gills running down the stem, not platelike and thus not easily separable from the cap and stem (try removing an entire "gill" with your fingers or a sharp object); mushroom usually not growing on wood. Chanterelles and Trumpets
Gills not as above; mushroom growing on wood or elsewhere. Gilled Mushrooms
Mushroom with pores on its underside (they may be very tiny; use a hand lens if unsure). 6
Pores absent. 9
Stem absent--or, if present, lateral. Polypores
Stem present and central. 7
Flesh in stem tough. Polypores
Flesh in stem soft. 8
Cap round in outline; pore surface not running down the stem, or only slightly running down the stem; spore print not white. Boletes
Cap round to irregular in outline; pore surface running down the stem; spore print white. Polypores
Mushroom with spines or "teeth"--either on the underside of a cap, or hanging from a branched structure, or clumped together in an indistinct mass. Toothed Mushrooms
Spines or teeth absent. 10
Mushroom covered in some part with a foul-smelling slime; arising from a soft underground "egg"; variously shaped (like a club or stick, like crab claws, like a lantern, like a Wiffle ball, etc.); frequently found in urban settings, but also found in woods. Stinkhorns
Not as above. 11
Mushroom shaped like a cup, a saucer, a goblet, a standing rabbit ear, a bowl, or a saucer that has split into star-like rays; with or without a stem. 12
Mushroom not shaped as above. 13
Goblet or cup with tiny "eggs" inside; mushroom very small. Bird's Nest Fungi

Mushroom more or less shaped like a ball, or like a ball raised up on a stem, or like a ball set on a starfish. Puffballs
Not as above. 14
Mushroom with a clearly defined, more or less central stem that is separate from a clearly defined cap. 15
Mushroom without a clearly defined cap and stem. 19
Cap shape convex to centrally depressed or vase-shaped; undersurface smooth, wrinkled, or gill-like; rarely fruiting in spring except in warm coastal areas. Chanterelles & Trumpets
Cap shape oval, pointed, lobed, saddle-shaped, irregular, or thimble-like (never vase-shaped or convex); undersurface absent, or hard to see or define; many (but definitely not all) species fruiting in spring. 16
Stem completely hollow, or hollow with cottony fibers inside; cap with pits and ridges, or longitudinally wrinkled, or fairly smooth (never lobed or convoluted); without reddish or reddish brown shades; found in spring. True Morels & Verpas
Not completely as above. 17
Most (but not all) species found in spring (in north-temperature regions); cap lobed, convoluted, "brainlike," or irregular, with brownish or reddish brown to reddish shades (never black, white, or gray when fresh). False Morels
Not completely as above. 18
Found in summer and fall (or spring in warm coastal areas); cap lobed, saddle-shaped, or irregular and whitish, grayish, brownish, or black; stem surface ribbed or "pocketed" in some species. Saddles
Not completely as above. Oddballs & Misfits
Mushroom thin-fleshed and vase-shaped or tubular--or vase-shaped and fleshy, with scales on the cap surface or with several caps arising from a shared stem. Chanterelles and Trumpets

Not completely as above. 21
Mushroom shaped like a branched or unbranched club or stick--or shaped like a coral (or a head of cauliflower); most species growing on the ground but a few growing on wood. Clubs and Corals
Not completely as above. 22
Mushroom growing on wood; shaped more or less like a fan or a kidney; underside smooth or vaguely wrinkled, but without pores or gills--or, mushroom without a clearly defined cap or stem, appearing more or less like a crust or a spreading surface that lacks a mushroom; usually growing on the undersides of downed logs.
