Cap (Pileus)
the umbrella or bell-like ‘hat’ of the mushroom. Holds the spores in either gills or pores, wrinkles or teeth
gill (lamina)
blade-like or leaf-like plate on which spores are produced, beneath the cap of an agaric
stem (stipe)
stalk or stem of the fruiting body of the fungus
Veil
A protective layer of tissue that may cover all, part or none of a mushroom
Barely attached gills
Gills that are adnexed (reaching to the stem, but not attached to it)
Bluntly attached gills
Gills that are adnate (broadly attached to the stem) or emarginate (same height for most of its length, then becomes shallower just before reaching the stem.)
Notched gills
Gills that are sinuate (just like emarginate gills, except they curve back down the stem for a little bit just before attaching.)
Decurrent gills
whole gill extends down the stem
Lamellae gills
Gills that reach the stem
Lamellulae gills
Shorter gills that may go halfway or just a short distance from the margin
Marginate gills
when the edges of the gill is differently pigmented than the face of the gills
Sessile
Stalkless mushrooms
Usually attached to a substrate like wood, living or dead herbacious plants, or another fungus
Lateral stem
If the stalk is attached at the margin of the cap
Usually are found on woody substrates
Eccentric stem
Off-center stalk
Glabrous stem
unadorned stems
Partial veil
Veil that covers the gills and then leaves a ring (annulus)
Universal veil
Veil that covers the entire fruit body
Evidence can be found as a freely removable wartlike patches on the cap
