Photographed. Keys to I. nitidiuscula in Matheny Key (ouna) Key (Sept 2002) but not good fit. Does agree pretty well w/ illustrations of I. splendens in Stangl (1989) & Mosa/Julich Fanbattas (Inocybe 29) Swiss Book #5. Fits I. s. var. splendens - except cap color in their photo darker than my material.
Compares well with holotype (as I. longipes Peck) except there are no cysts at stipe base in the holotype. B. Kropp. 28-Oct-07 Substrate: terricolous.
