About plant names...

Spotted corts are native to eastern North America. They are found in oak forests because they have a mutually bene­ficial, mycorrhizal relationship with the roots of oak trees.

Stem: 1-2½″ (3-7 cm) long × ⅛-½″ (5-15 mm) thick. Stems are fairly uniform in thickness, but thicker at the base. Stems are mostly white, sometimes with a faint purplish tinge. These mushrooms do not have a special odor.

Cap: Caps are 1-2″ (3-6 cm) in diameter, and purple, lilac, or blue in color. As they age, yellowish or brownish spots develop, clustered toward the center of the cap. Both cap and stem are slimy. The color, spots, and sliminess are distinctive features, narrowing the ID to this or Cortinarius iodeoides. Caps are convex, bell-shaped, or domelike in the center. Gills are attached to the stem, pale lavendar in color when young, brownish or grayish when older.

Spores: Spore print is rust-colored. If you have a microscope handy, spores are 8–12 × 5–7 µm, and ellipsoid. (The similar-appearing species Cortinarius iodeoides has smaller spores, also ellipsoid, measuring 7-8 × 4-5 µm.)

Edibility: These aren’t outright poisonous, but don’t eat them.
