Cortinarius mucifluus belongs to the subgenus Myxacium



Found growing with pine. Slimy cap and stem. Cap is brown in color. Stem is white and equal; sometimes slightly swollen at the base. Found in mixed woods with hardwoods (oak and beech) and pine. October. The spores of this collection fit Cortinarius mucifluus better than the go-to slimy Cort, C. mucosus, which has longer spores and an orange cap.
Spore image and measurements. Could not find a spore longer than 13 microns.
