The description of microscopic characters in based on a study of the type of Cortinarius punctifolis pk. Smith recognized that this species and Murrill's Flammula subviridis were one and the same. The pileus colors, and dotted gills, and filiform pileocystidia are distinctive. Many of the dried basidiocarps retain blue-green to green tints.
