Gilled mushrooms come in several different shapes, although typically we think of them as cap and stem mushrooms, and have historically called them ‘Agarics’. The gills are thin, fragile, downward-facing plates on which spores are produced within structures called basidia. Some gilled mushrooms do not have much if any stem, such as oyster mushrooms (Pleurotus species) and Crepidotus species. Others, such as Gilled Boletes (Phylloporus species) and Tapinella species are actually more closely related to boletes than to members of the Agaricales. Due to their unique structure consisting of principally spherical cells causing these fruiting bodies to break like chalk, Lactarius, Lactifluus and Russula species are listed in their own category.
To facilitate your search for particular gilled mushrooms, I have divided them into two general groups and distiguished them by whether their spores are pale or light-colored and those that are dark-colored. Light-colored spores can be white, cream, pale to dark yellow, and pink to salmon-pink.
To further facilitate finding photos and descriptions of light-spored gilled mushrooms, I have entered their genus names in accordance with whether or not they are TERRESTRIAL, grow from a WOOD, NEEDLE, LEAF, CONIFER CONE or NUT substrate, or are PARASITIC ON OTHER FUNGI.
Since several common Waxy Cap mushrooms (HYGROPHORACEAE family of the Agaricales order) have recently been separated into several genera, I am putting them into a distinct group within the pale-spored gilled fungi. Doing so should enable the mycophile to find particular species with ease. These fungi generally have thickish, slippery or greasy gills, sometimes the caps and stems are tacky to extremely viscid, and many are quite colorful. There are more pale or light-spored fungi than there are dark-spored.
