Key to Gilled Mushrooms KeyThis is a key to gilled mushrooms, that is, mushrooms having a definite cap with a fertile surface consisting of gills. The fruiting body usually also has a stem, although that may be lateral or absent (usually, then, the mushroom is growing from wood). You can use this key to identify mushrooms that you find.
Agaricales OrderFruiting body containing fibers (usually in the stalk)
Gomphidiaceae FamilySpore print smoky-olive to black
Gills very decurrent, becoming smoky in age from developing spores
Cap typically slimy, or at least viscid
Under conifers only
Gomphidius GenusFlesh (and gills, before they become colored by developing spores) white to greyish
Stalk typically yellow at the base (in one case it can be pinkish at the base)
Normally Slimy Gomphidius Section
Diagnosis
Narrow down your identification:
Gomphidius maculatusCap salmon to orange- or pinkish-cinnamon to reddish brown when young; staining black or blackening overall in age
Lower stalk coated with dark brown to purplish black fibrils
Gomphidius nigricansCap white or yellowish when young, becoming some shade of pinkish or vinaceous brown, and finally blackening altogether
Stalk base can be yellow or pink
Partial veil sparse, fibrillose; usually present on young fruiting bodies, sometimes leaving an annular zone on mature ones
