Field characters

Pileus: usually large, convex-planar, with large scales
Annulus: present and often "moveable"
Stipe: relatively large, cleanly separable from the pileus.
Ecology: saprophyte on the ground in lawns and woodlands. Often reoccurs on the same site yearly.

Micro characters

Basidiospores: spores large, typically > 8 micrometers (Largent and Baroni, 1988); 10 micrometers up to 25micrometers (Singer, 1986), with a large germ pore and metachromatic in cresyl blue, dextrinoid in the type species.
Cystidia: no pleurocystidia, cheilocystidia typically present
Spore Print: white or pale pinkish
Lamellae: free
Lamellar Trama: regular
Pileipellis: palasade (or trichoderm (


Singer transferred Lepiota procera to the genus Macrolepiota, which he created in 1948.

Again, this is a genus that not all accept. Arora, 1986 does not use Macrolepiota, but includes its species in Lepiota. Largent and Baroni, 1988 seem to accept it, as does Roody, 2003, Bessette et al., 1997 and Barron, 1999. It seems to me that the microcharacters are enough different to justify the separation, hence its inclusion here.
